Safety Management

1.1 Introduction (Prof Bryan Hickey)

Under the Health and Safety at Work Act 1974 [1, 2] and other health and safetylegislation the School of Physics and Astronomy is obliged to:

• Set standards so that the health and safety of staff, students, visitors and thegeneral public are not adversely affected by the activities of the School;

• Provide and maintain equipment and a working environment that are, so far asis reasonably practicable, without risks to health and safety;

• Train all students and staff to be aware of their own responsibilities for and toprovide information, instruction and training on the particular hazards and riskswhich exist within the school.

The University of Leeds Health and Safety Policy [4] sets out

• the University’s aims and objectives for the management of health and safety;

• outlines the organisation and arrangements for putting it into effect; and

• also outlines the arrangements for monitoring the policy.

The University Health and Safety Services website [3] provides detailed informationon specific topics. For individual groups, students, senior managers, specialists, staff,principal investigators, there are separate lists of the most relevant topics. While partsof this handbook reproduce University Health and Safety Services information thishandbook aims to

• describe the health and safety management functions and responsibilities whichare delegated to departmental staff;

• define and explain the safety procedures and rules which do exist within theSchool;

• to provide the health and safety information which is specific to the School ofPhysics and Astronomy.

1.2 Functions and Responsibilities (Prof Bryan Hickey)

1.2.1 Students

The University Safety Policy [4] draws the attention of all students of the Universityof Leeds to their legal responsibility, under section 8 of the Health and Safety at Worketc. Act 1974, not to interfere with or misuse anything, any objects, structures orsystems of work, provided by the University of Leeds in the interests of health andsafety. Students should

• report any accident at work which results in personal injury or ill health, how-ever minor, and every dangerous occurrence, including fire, using the approvedreporting mechanisms;

• report ”near miss” incidents which have the potential to cause injury or ill health,using the approved form;

• notify the Head of Health and Safety Services when suffering from a disease ormedical condition which may be caused by, or made worse by, work activities(this information will be treated as confidential);

• not proceed with any activity if they feel it poses a threat to their health andsafety, or to that of others;

• report any unsafe or unhealthy working conditions, or suspected faults in build-ings, building fabric, or in any equipment, to the Head of School, without delay;

• assist any visitors who may not be familiar with University procedures, to thebest of their abilities.

1.2. FUNCTIONS AND RESPONSIBILITIES (PROF BRYAN HICKEY) 3

Any member of staff or any student may contact Health and Safety Services foradvice and guidance.

1.2.2 StaffAll staff are responsible for their own health and safety, and the health and safety ofothers who may be affected by their acts and omissions. All staff must ensure that theyconduct their duties in a safe manner and in accordance with

• the University Health and Safety Policy

• any Faculty/School/Service Safety Policy or Guidance Notes

• any specific codes of practice relating to particular activities

• any relevant safety legislation and guidance.

Staff must ensure that they

• take reasonable care of themselves and have due regard for others

• where necessary help the University meet the duties imposed on it

• don not interfere with or misuse anything provided for health and safety

• bring any breaches of the safety policy to the employer’s attention via their LineManager or Health and Safety Manager

• report any accident at work which results in personal injury or ill health, how-ever minor, and every dangerous occurrence, including fire, using the approvedreporting mechanisms

• report ”near miss” incidents which have the potential to cause injury or ill health,using the approved form

• notify the Head of Health and Safety Services when suffering from a disease ormedical condition which may be caused by, or made worse by, work activities(this information will be treated as confidential)

• not proceed with any activity if they feel it poses a threat to their health andsafety, or to that of others

• report any unsafe or unhealthy working conditions, or suspected faults in build-ings, building fabric, or in any equipment, to the Head of School or Service, with-out delay

• assist any visitors who may not be familiar with University procedures, to thebest of their abilities.

1.2.3 Academic Supervisors (including Principal Investigators)

The health and safety management of research projects and other related academic ac-tivities is usually delegated to research supervisors and group leaders. This is assumedunless an alternative arrangement is agreed with the Head of School and written downas part of the research documentation. Their duties include


• ensuring that risk assessments take place at the planning stage of any researchproposal, and that the costs of implementing suitable risk control measures, anddisposing of any hazardous substances or materials, are included in the fundingarrangements;

• ensuring that risk assessments are reviewed and kept up to date as the researchproceeds, and that everybody involved in the work activity has read and under-stood the risk assessment;

• ensuring local inductions into the work area are carried out and recorded;

• ensuring that control measures such as guarding of moving parts; provision ofprotective equipment, are implemented and continue to be effective;

• leading on the performance of risk assessments and, where appropriate, workingwith competent people to carry out the risk assessments for their work, ensuringthose people remain competent and receive appropriate training, resource, ad-vice and support;

• ensuring that risk assessments are regularly reviewed. In the event of an incident,accident or process change, the risk assessment must be reviewed immediately;

• understanding the University’s health and safety policy statement, codes andguidance, how they are applied within the school, and within the working spaceof the research team;

• maintaining suitable records of exposure to substances hazardous to health, inaccordance with University policies and guidance;

• arranging for any necessary and appropriate health and safety training, includ-ing training identified in the risk assessment;

• liaising with specialist advisers, and providing information on request about therisks and control measures; and

• ensuring that all research group members respond to, and cooperate with anyrequests for them to attend for health surveillance and advice.

The health and safety management with respect to teaching is usually delegated toprogramme leaders and course/module leaders. The following duties are included inaddition to the duties set out above

• ensuring that class teachers, whether University employees or not, are fully in-formed of all risks and controls required as an outcome of any risk assessments;

• monitoring that work-based teaching in partner organisations is undertaken safelyand without risk to health.

To enable the Academic Supervisors to effectively carry out these responsibilitiesand, hence, ensure compliance with statutory requirements, the University will pro-vide essential training and development which Academic Supervisors are expected toattend. This will be supported by the production of appropriate standards and guid-ance.

1.2. FUNCTIONS AND RESPONSIBILITIES (PROF BRYAN HICKEY) 5

1.2.4 Staff with Line Management responsibilities

All staff with line management responsibilities including first line supervisors andunit/section leaders have an important role in setting performance standards for theirspecific area of responsibility and monitoring for standards in these on an on-goingbasis. They will ensure that risk assessments in their area are completed, that staff areaware of them and that staff are aware of and adhere to all relevant safety policies andarrangements.

To enable the Line Managers to effectively carry out these responsibilities and,hence, ensure compliance with statutory requirements; the University will provideessential training and development which Line Managers are expected to attend. Thiswill be supported by the production of appropriate standards and guidance.

1.2.5 Head of School

The University Safety Policy [4] describes the responsibilities of Heads of Schools:

• To have overall responsibility for ensuring effective health and safety manage-ment in your faculty, school or service

• To ensure compliance with both legal and University health and safety require-ments

• To ensure adequate time and resources are allocated for all the requirements tobe carried out

• To provide leadership for health and safety

• To ensure all staff are involved by promoting two-way communication

• To establish effective local health and safety procedures and communicate themwith staff

• To monitor and review health and safety performance within your faculty, schoolor service

• To take appropriate action when procedures have not been complied with

• To be involved with accident and incident investigations

• To ensure staff are competent to undertake tasks safely

1.2.6 Health and Safety Working Group

Day to day safety matters are dealt with by the members of the Health and SafetyWorking Group. The members of the group are listed in table 1.1 on page 6. Themembers of the Health and Safety Working Group, the Health and Safety Officer andthe Health and Safety Coordinator act as contact points and focal points for the issuesthat arise. The School Health and Safety Officer , the School Health and Safety Coordi-nator, the School Laser Safety Supervisor, the School Radiation Protection Supervisorand the Fire Wardens have specific tasks within their area or expertise. An appendixto University Health and Safety Policy gives guidelines regarding the ”Roles of Facultyor School Health and Safety Co-ordinators”.

Any health and safety issues which cannot be resolved by a supervisor or line man-ager should be raised with a Health and Safety Working Group member, with theHealth and Safety Officer or with the Health and Safety Coordinator in the first in-stance.

Table 1.1: School Health and Safety Working Group members

The Health and Safety Working Group carries out regular inspections of laborato-ries every 12 to 15 months. The members of the Health and Safety Working Grouphave the authority to stop any work in any laboratory, workshop or elsewhere in theSchool should the activity or the facilities not meet safety standards.

1.3 Safety inspections (Dr Joachim Rose)

There are safety inspections annually for each individual research group, teachinglab and workshop. The inspections are carried out by members of the Health andSafety Working Group together with trade union representatives. Collectively, theinspection team should have sufficient expertise to be effective in spotting potentialproblems. For example, when inspecting a research group using lasers the laser safetysupervisor should be present or a member of the team should have laser safety train-ing. No member of the inspection team should in effect review their own activities;there should be independent expertise present from another member of the inspec-tion team. The head of the research group (or the equivalent for non-research spaces)takes part in the inspection.

The inspection team produces an inspection report which contains a list of actionsitems. The report indicates the severity of a possible accident that may result fromthe identified problem. The report also indicates the likelihood of an accident. Theentries of low, medium, or high are used to decide which deadline to set. During theinspection the deadlines for remedial action are agreed with the head of group, towhom the report is sent promptly after the inspection.

It is the responsibility of the head of group to assign a group member for eachaction items or to find other ways of meeting the deadline. The inspection reportsare available to all staff on the share computer system file space. The head of groupreports to the School Health and Safety Officer or the Health and Safety Coordinatorthat the remedial work is complete by returning the signed inspection report. If anyproblems in meeting a deadline arise the head of group contacts the Health and SafetyOfficer or the Health and Safety Coordinator to discuss which measures to take. Afterreceiving the signed inspection report the School Health and Safety Officer or theHealth and Safety Coordinator (or another member of the safety committee) checks

1.4. RISK ASSESSMENT (DR JOACHIM ROSE) 7

that the identified safety problems have been dealt with. Finally the Health and SafetyOfficer or the Health and Safety Coordinator sign the inspection report to indicate thatall action items have been completed and sends a copy of the reports to the Head ofSchool. If there are still outstanding issues the Health and Safety Officer or the Healthand Safety Coordinator takes appropriate action. While the issue is being resolved theHealth and Safety Officer or the Health and Safety Coordinator or the Health andSafety Working Group may impose restrictions, shutdown some activities entirely orclose down whole laboratories or rooms.

1.4 Risk assessment (Dr Joachim Rose)

1.4.1 Legal requirement for risk assessment

The Health and Safety at Work etc Act 1974 [1] introduced the concept of reason-able practicability which implies the need for employers to protect persons affectedby their work and to provide a degree of control commensurate with the level of risk.The Management of Health and Safety at Work Regulations [10] take this one stagefurther by explicitly requiring employers to carry out a suitable and sufficient riskassessment. Health and safety risk assessment is the systematic identification of thehazards associated with an organisations work activities and premises; and the evalua-tion of the risks associated with those hazards: it then involves the identification of themeasures necessary to control these risks. The advice in this School Safety Handbookoutlines the standards to be achieved for various hazards. It also outlines the con-trol measures which ensure that the risks arising from these hazards are adequatelycontrolled. If however there are additional hazards or specific activities in the schoolwhich are not adequately addressed in the School Safety Handbook then the onus ison the school to develop and set standards for the hazard or activity.

1.4.2 Risk assessment procedure

The principal responsibility for risk assessment rests with the research group lead-ers, with the module leaders of laboratory based modules, and with the heads of theschool workshops. They have the responsibility to ensure that the risk assessmentsare carried out for new activities, that the assessments cover all significant risks, thatthe existing risk assessments are kept up-to-date and that the assessments are of a suf-ficiently good quality. Ideally the risk assessment is carried out by the person, forexample the researcher preparing a new activity, who will later carry out the activity.Each laboratory or workshop should be assessed in a one or more risk assessment doc-uments. Where the assessment of the significant risks becomes too complex, for exam-ple because there are several different workplaces or different procedures to consider,a number of individual assessment documents should be prepared. The complete riskassessment is signed by the group leader and forwarded to the School Health andSafety Coordinatorto be approved. Where reasonably practicable all risk assessmentsshould be displayed in the laboratory or workshop. Ideally the risk assessment shouldbe displayed together with the School Safety Notice and a copy of the School SafetyHandbook. If this is not practicable then all safety information for a laboratory orworkshop should be collected in a file which is visible and easily available to everyonein the laboratory or workshop.

The University has introduced software, RIVO, for risk assessment and COSHHassessment. Potential user are encouraged to try RIVO. The Faculty Health and SafetyManager can assist in getting started with the new procedure.


1.4.3 Guidelines for Risk assessment

The Health and Safety at Work Act requires that employers make a suitable and suf-ficient assessment of the risks to the health and safety of their employees and non-employees affected by their work. While the requirement to do risk assessments stemsfrom the law, the underlying objective of this is to ensure that risks arising from workactivities are controlled and that as a consequence of this no one engaged on workactivities gets hurt or becomes ill.

1.4.3.1 Definitions

Hazard means ”anything that can, or has a potential to cause harm” (e.g. chemicals,electricity, machinery, etc). Risk is the chance that someone will be harmed by thehazard. How to assess the risks in your laboratory/area.

1. Identify the hazards

2. Determine the people at risk

3. Evaluate the risks and decide whether existing precautions are adequate

4. Record the findings

5. Review the assessment and revise if necessary

1.4.3.2 Risk Assessment: Risk Ranking

The Health and Safety Executive use the simple equation:

RISK RANKING = HAZARD SEVERITY x LIKELIHOOD OF OCCURRENCE

Both the hazard severity and the likelihood of occurrence are categorised, or assessed,on the basis of a for example three point scale. For each category outline guidelinesare given to define that category. For Hazard Severity, (i.e. potential for loss), the threecategories are:

3 - High: Loss of life / permanent disability / Major injury; Extensive loss of plantor building infrastructure; Prohibition notice served by HSE / Prosecution

2 - MEDIUM: Serious Injury or Illness / Temporary disability; Some damage to plant,equipment; Improvement Notice served by HSE.

1 - LOW: Minor/ non-disabling injury or illness; Minor disruption to plant, equip-ment

For Likelihood of Occurrence, i.e. probability that loss or harm will result from haz-ard, the three example categories are:

3 - HIGH : once or several times per day/ or per activity

2 - MEDIUM : once or several times per month/ or per activity

1 - LOW : once or a few times per year/ or over lifetime of project

The product of the two values is used as the basis to determine the Risk Rankingfor each item. As a rough guide, a HIGH Hazard Severity, a HIGH Likelihood ofOccurrence or a HIGH RISK RANKING is undesirable and effort should be made toeliminate or reduce these as far as is reasonably practicable.

1.4. RISK ASSESSMENT (DR JOACHIM ROSE) 9

Professional judgement is required to categorise items which represent a breachof a specific statutory provision. Indeed such breaches are difficult to categorise interms of hazard severity and likelihood of occurrence and the assessors have to de-cide on whether a specific breach represents a significant issue of non-compliance, inparticular whether it would lead to internal or external enforcement action, and fromthis consideration, decide on whether risk is HIGH, MEDIUM or LOW. This is whyit is important for the assessor(s) to have an understanding of the significance of anystatutory breach which might arise from an activity. If the assessor is uncertain asto the significance of any breach then he/she can discuss this with the School SafetySupervisor, or other ”competent person”, before signing the risk assessment.

1.4.4 Hierarchy of Risk Control

Where an aspect of the activity is ranked as HIGH RISK then the assessor/s shouldconsider whether they have done all that is reasonably practicable to reduce risk tak-ing into account the following risk control hierarchy namely:

1. avoidance /elimination (of risks) e.g. contracting out to specialists with appro-priate facilities

2. substitution e.g. using a less hazardous substance or better guarded machine oragain subcontracting a dangerous activity

3. controlling risks at source reviewing engineering controls

4. safe systems of work reviewing system of work for activity

5. use of personal protective equipment (PPE) as a last resort to consider whetherPPE, as a complementary aspect to the above, could help to reduce risk. e.g.fume cupboard for expelling noxious vapours

Similarly when an aspect of the activity is ranked as MEDIUM RISK then the re-search/assessment team should again consider whether risks could be reduced furtherby going through the above risk control hierarchy. There is no need to do the abovefor LOW RISK issues but there is still an obligation to reduce risks to the lowest levelreasonably practicable.

1.4.5 Documenting the Risk Assessment

The Physics and Astronomy Risk Assessment template is available on the shared in-ternal file space within the /safety top level directory. The risk assessment proformaand any other relevant information e.g. Safe Operating Procedures, Method State-ments operators manuals etc. must be communicated to all persons involved withthe work. Therefore on an additional sheet those engaged on the activity will be re-quired to “sign up” to the fact that they have had the activity and risks associatedwith that activity explained to them, and that they have read and understood the riskassessment. Copies of the risk assessment and other documentation such as methodstatements should be displayed next to fixed equipment/processes or stored in theimmediate vicinity so that it is available for consultation or for inspection.

1.4.6 Monitoring, risk assessment and safety inspections

To ensure that the risk assessment procedures are operating satisfactorily the regularsafety inspections of workshops and laboratories examine the risk assessments.


Both positive examples of good practice and any action items arising from prob-lems are identified in the inspection report. Even though there are regular safetyinspections, all group leaders are still responsible to ensure a complete and accurateset of risk assessments is maintained. Whenever there is a significant change, for ex-ample, if a new potentially hazardous experimental procedure is introduced, then anew or modified risk assessment is needed.

1.5 Authorisation of laboratory work (Dr Joachim Rose)

Prior to the start of any laboratory work the students, staff or visitors involved needto first become authorised as users of the laboratory. The head of group, a directsupervisor or the laboratory manager can authorise users. In each case a decision ismade on whether the person is competent to safely work in the lab and has receivedall relevant information and any necessary training. The lab user authorisation formalso indicates whether any out of hours work can take place. The from is displayedin the lab together with the relevant risk assessments. Where there is a change in thelaboratory activities with a significant hazard a new risk assessment of the activity isneeded.

For a person to become a user of equipment or the user of a laboratory the relevantsafety training must be complete and documented. The new user must either completerisk assessments for new activities or follow the induction for established procedures.In either case there must be evidence that this process has been completed.

1.6 Authorisation of work by technical staff (Dr Joachim Rose)

All requests for workshop time must include the relevant health and safety informa-tion from the originator of the request. Before carrying out a task this information,which may in effect be a full risk assessment, is discussed between the technician andthe head of workshop, who authorises that the work is carried out. The request form isalso used to feed back safety information - new issues may have come to light - to thehead of workshop after completion of the task. Minor technical work without com-pletion of a job request and a subsequent discussion of the safety issues should - if atall - only take place if there are very clearly no significant hazards.

1.7 Accident Reporting (Dr Joachim Rose)

The University of Leeds Safety Services operate the accident reporting system (Sen-tinel). The Health and Safety Coordinator and other members of staff are trained inthe use of the accident reporting system. A list of trained staff can be found on theSchool of Physics and Astronomy web pages.

The advice from the University of Leeds Safety Services is to record all accidents,however trivial (let common sense prevail) and also all Dangerous Occurrences (’nearmisses’). The guiding rule is: If in doubt report it. Accidents reports - even of veryminor incidents - are a valuable source of information, as they can reveal a hazardthat has so far escaped the effort to eliminate or control risks.

Chapter 2

Specific Hazards and Procedures

2.1 Fire (Mr Stuart Weston)

The University of Leeds Safety Services web page provide Fire Safety information ontheir web site, http://www.leeds.ac.uk/safety/fire.

You should know the location of your assembly point outside the building and thedesignated emergency escape routes from the building. The emergency escape routeand the assembly point depend on where you are in the building. Anyone working inthe School should also know the location of the nearest fire extinguisher and of thenearest fire alarm point.

2.1.1 Fire Alarm procedure

Circumstances must dictate whether attacking a fire with portable fire-fighting equip-ment should take priority over summoning the fire service and raising the alarm.Clearly it is undesirable to allow a small fire to take hold through waiting for out-side help but it can be dangerous to delay calling for assistance in dealing with anyoutbreak which may not be quickly extinguished by prompt action. Only use firefighting equipment if the full extent of the fire can be ascertained and you are con-fident that the fire can be easily extinguished. In all other cases the alarm shouldbe raised by breaking the nearest break glass call point. If your efforts to extinguishthe fire are unsuccessful raise the alarm. Security will be alerted automatically but ifthere is time contact the Security Office on Ext 32222 with details (i.e. building, roomnumber). Every case of fire must be reported to the School Health and Safety Officeror the Health and Safety Coordinator.

2.1.2 The Fire Alarm System and evacuation of the building

As well as manual break glass call points located on emergency escape routes thereis an automatic fire alarm system utilising smoke detectors. When either is activatedelectronic sirens will sound throughout the School. On hearing the fire alarm siren

• you must leave at once and make for the official assembly points. Do not wait tobe asked to leave.

• if at all possible make safe any potentially dangerous equipment or experimentsfirst.

• do not congregate around the exits and in particular keep the area around thebuilding clear for emergency services to gain access and park.

• do not leave the assembly area or re-enter the building until given permission todo so by the Fire Officer or Fire Wardens even if the alarm has ceased to sound.

11

http://www.leeds.ac.uk/safety/fire

12 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES

• never use lifts after the fire alarm has sounded.

The only circumstance in which people may remain in the building is during abrief equipment test which use a different sound and which has been announced.

2.1.3 Fire protection equipment

• Fire Extinguishers: Fire extinguishers are available in all laboratories, each witha security tag. Every worker must know the position of these fire extinguishers,type and method of operation. It is too late to learn this when a fire starts! Ifyou use a fire extinguisher or note the loss of the security tag this must also bereported to the School Safety Supervisor or a Fire Warden to obtain a promptreplacement. Remember a colleague’s life may depend on it.

• Fire Blankets: These are provided in red containers fastened to the wall at variouspoints in the building. They are primarily intended for use when clothing catchesfire and may be quickly removed from their containers by a downward pull onthe tape attached to the blanket. Wrap the victim in the blanket and make themroll on the floor. The use (or unpacking) of a fire blanket must be reported to theSchool Safety Supervisor.

• Fire Doors: Fire resistant doors are strategically placed in corridors and at theentrance to laboratories to limit the spread of fire and smoke throughout thebuilding. Never leave such doors wedged open. Please be vigilant to make surethey are closed at all times.

The School has appointed Fire Wardens whose main duties are to assist in the evacu-ation of the building in the event of fire. On these occasions they normally wear anidentifying arm band or a high visibility vest. The Fire Wardens regularly check thefire protection equipment. Fire precautions and other related activities are coordi-nated by Mr Stuart Weston.

2.1.4 Fire Wardens

A list of fire wardens can be found on the School Health and Safety web pages. Theduties of School Fire Wardens include:

1. monthly check of the alternative exit routes.

2. ensure that all staff and post graduate students are familiar with the alternativeroutes.

3. check that corridors and staircase enclosures are not used for the storage of com-bustible materials.

4. check that fire resistant and self-closing doors are not wedged open or fastenedback.

5. carry out a monthly check of fire fighting equipment.

As part of fire drills fire wardens ensure that staff and post graduate students areaware of the procedures to adopt when:

1. a fire is discovered

2. on hearing the fire alarm

2.2. ELECTRICAL SAFETY (MR RICHARD OLIVER) 13

3. ensure that the area is evacuated.

4. assist Security to prevent any persons re-entering.

5. liaise with the Safety Officers and or Security regarding any local knowledgewhich may be of assistance to the Fire Authority.

Re-Entry Procedure:

1. at small incidents liaise with Security regarding the re-entry.

2. at prolonged incidents or where contamination is suspected liaise with the SafetyOfficer, the assistant Safety Officer or in their absence the representative from theDivision of Works and Services.

3. if requested to do so assist the Safety Officer or the representative from the Di-vision of Works and Services to carry out any safety tasks prior to the generalre-entry.

Evacuation Drills:

1. where practicable arrange for evacuation drills to be carried out annually.

2. where a full evacuation drill is impracticable an evacuation exercise should bearranged annually.

General Fire Precautions:

1. give advice and approval on the use of naked flame and the heating of com-bustible materials.

2. ensure that LPG and open element electrical fires are not used.

3. inform the Safety Service on any change which may effect the means of escape orother fire precautions.

2.2 Electrical Safety (Mr Richard Oliver)

Follow this code of behaviour:

1. All incoming new electrical equipment should be channelled through the SchoolStores, so that it is recorded on the School Register for a PX Number to be allo-cated, after which it must be tested for electrical safety (using a Portable Appli-ance Tester (PAT)). The details of the tests are then downloaded onto a database.In this way the frequency of the tests for particular electrical equipment can becontrolled. There should be regular visual inspection of items particularly proneto wear or abuse e.g. flex and cable, at reasonable intervals.

2. Do not interfere with any electrical apparatus or equipment or attempt to repairit unless you are an electrician and authorised to do the work.

3. All plugs must be in good condition. Any damaged plugs or plugs which get hotwhen in use must be changed. Whenever possible, 3-core cable should be usedto permit proper earthing of apparatus.

4. Do not change fuse ratings arbitrarily, Electricians are the right people to deter-mine and set the fuse ratings. All 13 amp three pin plugs must be fitted with afuse rated for the equipment concerned.


5. Keep distribution boards and similar installations clear of obstruction and waterspillage at all times. Do not overload distribution boards or adapters. Heatersand Electric Kettles should always be connected directly to the wall outlet andnot to a distribution board. If in doubt, contact the Electronics Workshop foradvice.

6. Where extension multi-sockets are used, care must be taken to ensure the totalloading does not exceed 13 amps. Extension multi-sockets should not be daisy-chained together.

7. Do not improvise with electrical equipment, this means:

(a) Never jam wires into sockets with matchsticks or nails.(b) Never run power tools from lighting sockets.(c) Never hang flexible cables over nails, leave them where they can get dam-

aged or wet, or frozen if liquid Nitrogen is likely to be spilled. Do not usethem to lift or pull the equipment to which they are connected.

(d) Where possible, cables should be strapped into a neat bundle and secured.(e) Cables crossing open floor areas should be covered with cable protectors.(f) The interchanging of cabling between appliances should be avoided. This

will ensure correct fuse ratings for the appliance.

8. Large items of metal equipment (e.g. laser tables, lathes, vacuum line framesetc.) should be separately earthed. Accidents have resulted when such apparatushas become live.

9. Report details of any ineffective or damaged electrical equipment to the Elec-tronics Workshop Supervisor. Do not use it until it has been repaired.

10. It is illegal under workplace law to intentionally or recklessly interfere with ormisuse any electrical equipment. Never override any safety interlocks.

11. The Electronics Workshop run courses in the use of the PAT tester so that groupscan then carry out their own electrical safety checks using the PAT tester. Thisnormally records the Earth bonding, Insulation resistance and load current. Mainsleads should be PVC coated, colour coded Brown (live), Blue (neutral) and Green-Yellow (earth) and be of the correct current rating for the equipment concerned.Serious accidents to personnel and damage to apparatus can result from failureto observe this wiring rule. Some equipment of foreign manufacture may notcomply with this colour code. In cases where foreign colour codes are used amember of Electronics Workshop staff should be consulted. Visitors from over-seas please note that the British system of colour coding is different from thatused in certain other countries. The use of private electrical equipment must bereported to a member of Electronics Workshop staff who will arrange for it tobe tested. If any electrical equipment is disposed of the Electronics Workshopneed to be informed of its appliance number. Further details on PAT testing areavailable in appendix C

2.3 High Pressures (Mr Stuart Weston)

2.3.1 Pressure Vessels

Pressure vessels (operating above 1.5 bar or 22.5 psi), or when the product of pres-sure (in bars) and the volume in litres exceeds 250 bar litres, officially require annual

2.4. MANUAL HANDLING (MR STUART WESTON) 15

inspection and certification and should only be used if they have a valid current cer-tificate. Before ordering pressure vessels or starting to operate any pressure vessel theSchool Health and Safety Coordinator (Mr Stuart Weston) should be contacted.

2.3.1.1 Gas Cylinders

Cylinders must not be moved with the regulators attached. Cylinder trolleys mustnot be used to store cylinders. A cylinder must never be left free-standing but be se-curely clamped or held in a proper stand. Cylinders must be fitted with regulatorsappropriate to the type of gas and cylinder pressure. Oxygen cylinders, in particu-lar, should only be used with oxygen gas regulators. Regulators must not be greasedand normal PTFE tape must not be used to help seal cylinder regulator connections.Grease and normal PTFE tape (which is highly plasticised) can spontaneously com-bust/explode in contact with compressed oxygen. A more expensive grade of safePTFE tape (from Manchester Valve and Fitting) can be used. Whilst this is mainlyintended for use in connection with oxygen lines, since confusion can easily occur, itis recommended as the only grade for all uses. Return faulty regulators and reportleaking cylinders to Stores. Diaphragm valves have a useful life of about five yearsand should have either a date of issue or retest date label and should not be usedafter this date. It is good practice to fit cylinders of flammable gas with an appropri-ate flash arrestor and for some applications this is required as for example when themixture formed downstream is inflammable or potentially explosive (e.g. hydrogen/air-oxygen or hydrocarbon/air oxygen). For further details consult the HSE websitehttp://www.hse.gov.cdg/pdf/safusgc.pdf

2.4 Manual Handling (Mr Stuart Weston)

The Manual Handling Regulations 1992, in principle, require generic risk assessmentsto be made for all lifting, carrying, moving tasks, etc. In practice this only becomesa regular problem for a few members of staff but there are obviously some jobs andsome circumstances (e.g. for new or expectant mothers) where the risks are real andneed to be considered very carefully. Never try to move very heavy equipment on yourown. Remember that manpower can be provided at both University and School leveland that lifting equipment suitable for some difficult jobs is kept by the MechanicalWorkshop. The HSE publication Guidance on Manual Handling Regulations is usefulor and manual handing web pages ar http://www.leeds.ac.uk/safety.

2.5 Office Safety (Dr Joachim Rose)

The University has produced detailed training material and protocols for office safetywhich those working principally in an office environment need to read.

In particular everyone regularly working with Display Station Equipment mustcarry out an online risk assessment of their workplace. This includes a training ele-ment in the safe use of DSE. See the web pages at http://www.leeds.ac.uk/safety.

A common cause of overheating of office equipment and sometimes of fires is theobstruction of the ventilation, particularly with thoughtlessly placed sheets of paper.Unless closed on sides electric radiators including fan units should not be used.

Office equipment must carry a valid Portable Appliance Test (PAT) label or not beused.

2.6 Flood, gas leaks and electrical breakdown (Mr Stuart Weston)

During the working day cases of floods, gas leaks or electrical breakdown should bereported directly to Works and Services (tel. 35555 ) and the School Safety Supervisorshould also informed. After normal working hours University personnel are at homebut on stand-by. They can be contacted through the Security office. Contact UniversitySecurity Ext. 32222 and report the incident. You must give your extension number.The Security Officer will telephone the appropriate person on stand-by. In some casesit will be possible for you to talk directly to the person concerned. Otherwise theSecurity Officer will relay your report.

2.7 Out of Hours Working and Working Alone (Dr Joachim Rose)

Working out of normal hours, before 8:00 or after 18:00, or working alone can increasethe severity of an incident or accident. For example, the person involved can becomeincapacitated and therefore not able to summon help. Even if an alarm is raised theremay be no trained or knowledgeable staff present to help (first aiders, co-workers,technical staff).

Experimental work out of normal hours or alone therefore requires a risk assess-ment that addresses the additional hazards and the increased severity of incidents thatmay arise. The risk assessment must be approved prior to authorising any out of hourslaboratory work. Additional risk assessment guidelines apply:

• Laboratory work alone or out of normal working hours should only be consideredif it is unavoidable.

• Any risk of the person(s) involved becoming incapacitated and thus unable to getassistance is not acceptable. Any such activity is forbidden while working aloneor out of normal hours.

• The risk assessment must detail the measures to either eliminate or else to sub-stantially reduce the impact of incidents while working alone or out of normalhours.

• An emergency plan, attached to the assessment and posted at the workplace,must detail how to respond to the situation and especially how to raise the alarmand how to obtain any necessary assistance (security, fire brigade, first aider,technical help).

• In case of an unrelated incident, for example a building fire, Security (first con-tact for fire brigade and ambulance services) need to know who is present in thebuilding and where. The risk assessment must therefore outline a procedure toguarantee that the information is available to Security and that it is correct.

In future a swipe card system at every laboratory door may provide information toSecurity. Until then other arrangements must be operated to inform Security. Recordsshould be kept to monitor that the arrangements are working.

Out of normal hours office work alone or computing work alone in a low hazardenvironment is discouraged. Where available a swipe card system or an internet loginsystem must be used to ensure the presence and location of the person in the buildingis known.

There are procedures for the use of the School telescopes at night. Before the firstnight of unsupervised observing with the one of the School telescopes, first contact

2.8. UNATTENDED OVERNIGHT EXPERIMENTS (DR JOACHIM ROSE) 17

Prof M G Hoare to discuss how to get access to the telescopes and which precautionsand safety rules to follow while observing. The list of rules is posted on the telescopeweb site, in the telescope warm room, and paper copies of the list are given out.

2.8 Unattended Overnight Experiments (Dr Joachim Rose)

Minimise overnight running of experiments to the absolutely necessary minimum. Ifany experiment or equipment is left on overnight it is your responsibility to makesure that it is safe and fail-safe. The required risk assessment for an overnight experi-ment or processes needs to address the increased hazard and the describe the specificmeasures to eliminate or reduce the hazard.

2.9 Teaching labs and project work (Dr Peter Hine)

2.9.1 Laboratory safety tours

All students working in one of the teaching laboratories for the first time or startingproject work are required to take part in a safety tour of the laboratory. This safety tourinforms the students about the location of safety equipment, such as fire extinguishersor first aid boxes, and of the safety procedures, for example in the event of a fire. Theattendance of students is recorded to make sure all students do take part.

2.9.2 Laboratory experiments

The handbooks for undergraduate laboratory modules include information on generallaboratory safety and on the general safety procedures. In addition both the UniversityHealth and Safety Handbook and the School Health and Safety Handbook are availablein teaching laboratories. For undergraduate laboratory experiments which are notcovered by the general safety information and the safety procedures in the handbookextra more detailed safety information is provided. This is done either by includingthe safety information in the description of the experiment in the laboratory handbookor by displaying a safety note at the workplace. Additional detailed information, forexample risk assessments, COSHH assessments or rules for working with radioactivesources, should be referred to and should be attached in appendices.

Like any other possibly hazardous activity undergraduate laboratory work requiresa prior risk assessment. Some experimental activities may require their own detailedrisk assessment, while other experiments may be included in a generic risk assessmentcovering the activities in the lab. The risk assessment are displayed in the laboratoryand should be discussed by the demonstrators with the students before allowing stu-dents to start on a new experiment.

Demonstrators and staff will ask a student to leave the laboratory, if they havereason to think that the student is insufficiently prepared to work safely or that thestudent is not following the health and safety procedures and rules.

2.9.3 Project work

Dissertation type projects, which may include some computer work, do not require thecompletion of a project safety note. For experimental projects a safety note is requiredand is drafted by the project supervisor. The note is then discussed and signed by boththe project supervisor and the project students before the start of the project work. Acopy of the safety note is kept by the students and is displayed at their workplace. Afurther copy is held by Dr Hugo Christenson(level 3) or Dr Stuart Lumsden(level 4).Any safety issues should first be discussed with the project supervisor. If uncertainties


remain then students and staff are encouraged to contact the module leader, the SchoolSafety Supervisor or any member of the School Safety Committee.

2.9.4 Teaching laboratory safety management

The safety of laboratory experiments and of project work is the responsibility of themodule leaders in close contact with the School Safety Supervisor. The members ofthe school safety committee assist in the assessment of potential risks such as lasers,radiation sources, or the use of chemicals. The school safety committee carries outregular inspections of the health and safety arrangements in teaching laboratories.

2.10 Non-ionising radiation (Dr Ben Johnson)

2.10.1 Laser safety procedures

2.10.2 What is required

Every new laser user in the school is required to register with the School Laser SafetySupervisor and with the University Radiation Protection Service. Registrations formsare available from the School Laser Safety Supervisor. New laser users are also re-quired to attend the University laser safety course, where notes on protection againstnon-ionising radiation’ [3] will be issued and a certificate of attendance will be pro-vided. This certificate is a requirement for all researchers working in the Universitywith lasers, class 3b or above. It is both the user’s and the research supervisor’s respon-sibility to ensure that the registration and any relevant training is completed beforework commences.

Every laser user in the school is required to adhere to the operational and safetyprocedures outlined the Universities "Local Rules for the Safe Use of Lasers" - a copyof which can be obtained from the Laser Safety Officer. [7]. N.B. The whole area ofLaser Safety is currently being reviewed at the University Level, with new guidanceand procedures due to be implemented towards the end of 2011.

2.10.3 School Laser Safety Supervisor

The School Laser Safety Supervisor conducts an annual laser safety inspection in thecontext of the risk assessment made by the laser user. The School Laser Safety Super-visor provides advice on laser safety procedures and sources of supply for laser safetyequipment.

2.10.4 Procedure in case of an accident

Depending on the seriousness of the accident the priority is to obtain medical atten-tion for the injured party. A list of School First Aiders is displayed in all laboratoryareas. The accident should be reported (see the section on accident reporting on page10) and the School Laser Safety Supervisor informed. The School Laser Safety Super-visor will assess the cause of the accident and will require that precautions are takento prevent a repetition. The user will be required to assist in this follow up procedure.

2.10.5 Microwaves and UV Radiation

All persons intending to work with microwaves at high power (e.g. microwave ovens)or ultra-violet radiation must discuss their work with the Radiation Protection Super-visor of the School. Long term exposure to bright light, particularly in the ultra violet,can lead to premature ageing of the eye and cataract formation in later life.

2.11. IONISING RADIATION (DR PETER HINE) 19

2.11 Ionising Radiation (Dr Peter Hine)

2.11.1 Local Rules (University of Leeds, Part 2)

It is the responsibility of all members of the School who wish to carry out experimentsinvolving the use of ionizing radiations to be aware of:

1. the statutory regulations governing the use of ionizing radiations

2. the University regulations relating to the use of ionizing radiations

3. the School Rules governing the detailed application of the regulations in 1 and 2.

A copy of the Local Rules, Part 1, is issued to prospective ionising radiation workersby the University Radiation Protection and Safety. The School Rules are set out belowand all radiation workers are given a copy of this document before they start work.

2.11.2 Registration

A risk analysis carried out by University Radiation Protection Service has concludedthat the four research grade x-ray diffractometers situated in room 8.237 and the stu-dent x-ray experiments situated in the undergraduate labs are inherently safe in de-sign. It has therefore been deemed by the University Radiation Protection Service andSafety Service that only members of the school who are directly involved in main-tenance /or live alignment of the x-ray optics should be registered with UniversityRadiation Protection Service (http://rsid.leeds.ac.uk/). Note that all users must stillregister with the School Radiation Protection Supervisor (SRPS).

All prospective new users must first contact the SRPS (Dr Peter Hine for under-graduates or Dr Mannan Ali) who will arrange training and ensure that all safetyaspects have been highlighted. Short term visitors to the School who wish to use anyradiation facilities should contact the SRPS before starting work in order to obtaintemporary clearance and local registration.

2.11.3 Purchase of Radioactive Sources or Radiation Generators

Any new proposal to use or purchase a radioactive source or an X-ray generator must,in the first instance, be discussed with the SRPS. Orders for radioactive materials orsources must be countersigned by the SRPS(Dr Peter Hine) or, in his absence, by theSchool Safety Supervisor. All radioactive materials or sources must be purchased viaUniversity Radiation Protection Service in conjuction with Dr Peter Hine.

2.11.4 Location of Radioactive Sources

Radioactive sources are under the control of Dr Peter Hine. Sources may not be re-moved from the designated rooms, transferred from one location in the School to an-other or removed from the School without notifying either Dr Peter Hine(SRPS) orUniversity Radiation Protection Service.

2.11.5 Return of Radioactive Sources after Use

Radioactive sources no longer needed for a particular piece of work must be returnedto Dr Peter Hineeither for storage or, if applicable, disposal via the University Radia-tion Protection Service.

2.11.6 Dosimeters

Dosimeters are no longer used in the school for day to day users.


2.11.7 Controlled Areas

Certain areas in the School are designated as “Controlled Areas” (Appendix B.2) .These areas may only be entered by persons who are working to an appropriate schemeof work. For the purposes of the rules a “Controlled Area” may be a small volumeforming part of a piece of experimental equipment. Such areas will be clearly labelledand identifiable. “Entering a Controlled Area” does not necessarily mean entering itwith the whole body.

2.11.8 Cleaning of Rooms

The only relevant rooms are room 8.237 where the Polymer X-ray generators are housedand the teaching laboratories. The cleaners come in daily to sweep the floor. No specialprecautions or warnings are issued since the X-ray tube heads and associated equip-ment in room 8.237 are housed in 100% radiation proof enclosures and there is noradiation background in the rooms over the normal environmental background whichis common to all rooms. The equipment in the teaching laboratories is switched offoutside normal laboratory hours.

2.11.9 Summary of Sources of Ionising Radiation in the School

2.11.9.1 Radio nuclides

All sources are sealed and of comparatively low activity. Holdings have been allo-cated to the School under the Radioactive Substances Act 1993. A current list ofactual sources held and their location is maintained by the School Radiation Protec-tion Supervisor (Dr Peter Hine) and is mirrored on the University Radioactive SourceDatabase. At the beginning of each academic year the Radiation Protection Servicesaudits the sources and wipes for leaks. A copy of the report is sent to the SRPS. Theclosed SPUCRS registration certificate is displayed with the sources and on a noticeboard. Each month these sources are checked in their storage cupboard located inroom 8.10j. Whenever these sources are used in the second year teaching laboratorythey are kept in a temporary, lead protected storage area. New additions to the stockof sources and any movement from the School are reported to the Radiation ProtectionServices when they occur. A current copy of the Registration Certificate is displayedon a School Safety Notice Board in the Small Common Room.

2.11.9.2 Machine Sources

All machine sources are X-ray Generators used for X-ray crystallography.There are four research grade x-ray diffractometers situated in Room 8.237 (x-ray

Lab). Four Rontgengerat Leybold didactic generator 55481 capable of 1 microsievertper hour situated room 8.10 (UG Lab) along with five miniature generator/goniometers-Tel-X-Ometer situated room 8.30(UG Lab).

2.11.10 Regular Testing of X-ray Generators

The superstructures of the three DG2 generators in room 8-237 are all surroundedby interlocked enclosures. These are checked for radiation leakage by the SRPS orby an appointed person every six months using an appropriate monitor (Provdied byUniversity Radiation Protection Service) and the results are recorded in a book whichis kept in the laboratory and the SRPS (Dr Peter Hine) is informed of the results. Anyproblems are dealt with and the leakage rectified before the generators are used. TheTel-X-Ometer and Leybold didactic generators in room 8.30/8.10 are tested (Dr PeterHine) for leakage at the start of each term when they are to be used and a written

2.12. FIRST AID (MR STUART WESTON) 21

record is kept of the results.

2.12 First Aid (Mr Stuart Weston)

Before beginning any work the location of the nearest qualified First Aider and of thenearest first aid box should be established. A list of qualified first aid personnel, theirlocations and phone numbers, and a list giving the location of all first aid equipmentin the school should be displayed in all laboratory areas.

Any use of a First Aid box should be reported to a first-aider who will arrangereplenishment of any items used. Before ordering new First Aid supplies please con-tact the School Health and Safety Coordinatorfor advice. Even when no First Aider iscalled then accidents and incidents should still be reported. See the section of accidentreporting 1.7.

Arrangements for First Aid in the school are co-ordinated by Mr S Weston (phone33819), who can give advice on becoming a First Aider, training, and on first aid equip-ment. The Student Medical Practice are prepared to provide on-campus assistance inemergencies but recommend that injured personnel or students are taken directly toLeeds General Infirmary (LGI) Casualty school. The Student Medical Practice can becontacted on telephones with an outside line on 9 295 4488 or on internal telephonesvia the Security Office 32222 .

The School aims to train all first year postgraduates in first aid. This training ispart of the generic skills training. The qualification as a First Aider remains valid forthree years.

2.13 Undergraduate project safety (Dr Peter Hine)

At the start of any undergraduate project work a project safety note should be draftedby the supervisor and is then discussed with the project students. The project safetynote includes:

1. Module code and module title:

2. Project title:

3. Project supervisor(s):

4. Project student(s):

5. Before start of project:

6. Each student should consult the School Safety Handbook and know where to findcopies of the handbook.

A laboratory safety tour of all relevant laboratory areas takes place. The safety risksand the safety procedures for the project are:

1. Manual handling:

2. Electrical hazards:

3. Chemical substances:

4. Lasers or ionizing radiation:

5. Other risks and procedures:


6. Arrangements for working unsupervised, alone, or out-of-hours:

7. The safety risks and relevant safety procedures for the project have been dis-cussed between supervisor(s) and project student(s). All safety questions arisinghave been answered. The information in this safety form is complete and correct.Any safety actions required before the start of the project work have been taken.

8. Signature(s) of project supervisor(s), date:

9. Signature(s) of project student(s), date:

Project students are encouraged to immediately contact Dr Hugo Christenson(level3 projects) or Dr Stuart Lumsden(level 4 projects) or the School Health and SafetyOfficer about any safety concerns that still remain after discussion with the projectsupervisor.

2.14 Chemical Safety (Dr Ben Johnson)

2.14.1 Chemistry Procedures

2.14.1.1 General

Much experimental research involves the use of hazardous chemicals particularly forthe preparation of samples, from simple cleaning with common solvents to com-plex organic synthesis. The COSHH regulations (Control of Substances Hazardousto Health) require that all activities involving the use of hazardous chemicals must beassessed by the person concerned before the procedure is carried out and checked bya responsible person (see below). Most laboratories have their own local procedures.For the Main BioPhysChem Lab (8.331) and the Satellite BioPhysChem Lab (8.312),the essential rules that everyone (including those not intending to use the lab) needsto know are:

Access is strictly controlled (through an electronic system) and will only be grantedonce a full lab induction has been given by Ben Johnson.

1. Special local rules apply (read notices on the door) especially including

(a) There is CCTV in use for the purpose of safety management and security.

(b) Lab Coats and safety specs must be worn at all times.

(c) Laboratory hours are 8.30 am to 5.30 pm unless an out of hours risk ass-esment has been completed and fully authorised and the control measuresimplemented.

2. Any chemical process must have a completed COSHH form associated with it inthe red folder in the lab. Even if the process has been deemed non-hazardous,the COSHH form shows that the chemicals and the process has been assessedand been designated as non-hazardous

3. All stock chemicals must be on the inventory database. Any items found not onthe database will be disposed of, without notice. All chemicals must be left ina clean and safe state and be clearly and correctly labelled: What, Who, When,Hazard. The labs are communal facilities and good housekeeping is to be ob-served at all times.

2.14. CHEMICAL SAFETY (DR BEN JOHNSON) 23

2.14.2 COSHH

The essential purpose of the COSHH regulations (Control of Substances Hazardous toHealth) is

1. to know the hazard of the chemicals involved (both initial and reaction products)and

2. to minimize the risk of people being exposed to that hazard.

The COSHH regulations require that all experiments etc. involving the use of chemi-cals must be assessed by the person concerned according to hazard and risk before theprocedure is carried out. Normally this involves filling in a COSHH form which can bedownloaded from the School of Physics website (under Safety) and filled in electroni-cally. It is then scrutinized, checked and the experimenter cross-examined about theirprocedure by a responsible person familiar with COSHH and who then signs the form.(At the time of writing, COSHH authorisers are Ben Johnson and Hugo Christenson).The signed COSHH form must be clearly displayed adjacent to the experiment beingundertaken (red file near door for the Chemistry Lab). It should be clear, concise andreadable by anyone. In the event of an accident etc., the COSHH form provides infor-mation for any rescuer of the hazard and risk of the experiment. The COSHH formcontains a number of sections:

1. Personnel involved:

2. Workplace: laboratory no etc.

3. Brief description of experiment: it is useful to include here the amounts of thesubstances involved.

4. Substances involved: clear and precise name.

5. Hazards identified: simple readable descriptions, e.g. corrosive, flammable, irri-tant etc.

6. Sources of information: all chemical suppliers are required to provide safetysheets on the chemicals they supply. This is usually too much information, pro-vided to cover the supplier’s back and is not always very helpful. Other informa-tion is available in suppliers catalogues and in the library.

7. Precautions to be taken:

(a) under normal conditions (storage, handling, etc) e.g. wear specs, gloves,handle in fume cupboard etc.

(b) in an emergency: e.g. how to deal with spillage.

8. Procedure for disposal of waste material: when the experiment is complete howis the waste to be disposed of. If it cannot be thrown away or flushed down thesink, it can be disposed of formally via the waste management procedure.

2.14.3 Advice on how to assess risk

The COSHH forms and advice on the assessment of risk may be obtained from BenJohnson who also has the relevant literature. If the substances involved are particu-larly hazardous then the assessor should seek sustained and professional advice, possi-bly from several sources. It maybe necessary to undertake the experiment in speciallycontrolled premises outside the School of Physics.


2.14.4 Waste Disposal

Anything which could be seen by the general public as offensive (e.g. gloves, plastictubes, petri dishes etc) must be disposed of in an Offensive Waste Bin. These are avail-able from Ben Johnson, who will also arrange their emptying and disposal when full.Only certain chemicals can be thrown in the bin or poured down the drain. The restneed to be disposed through Ben Johnson in a controlled and specified manner. Benneeds to be informed of what the material is, its likely hazard, the quantity, whose it is(or contact name), the origin (radioactive or hazardous materials must be negotiatedin advance) and where it is presently located. Materials left for waste disposal mustnot be left in a hazardous state, and must be clearly labelled what, hazard, who. Benwill then arrange for the items to be safely stored in a designated area until collectionby an outside company.

2.15 Working at Height (Mr Stuart Weston)

The Work at Height Regulations 2005 apply to all work at height where there is a riskof a fall liable to cause personal injury. They place duties on employers, the self-employed, and any person that controls the work of others (for example a workshopmanager, a principal investigator or a module leader who may direct others to work atheight). The Work at Height (Amendment) Regulations 2007 which came into force on6 April 2007 apply to those who work at height providing instruction or leadership toone or more people engaged in caving or climbing by way of sport, recreation, teambuilding or similar activities in Great Britain. As part of the Regulations, duty holdersmust ensure:

• all work at height is properly planned and organised;

• those involved in work at height are competent;

• the risks from work at height are assessed and appropriate work equipment isselected and used;

• the risks from fragile surfaces are properly controlled; and

• equipment for work at height is properly inspected and maintained.

There is a simple hierarchy for managing and selecting equipment for work at height.Duty holders must:

• avoid work at height where they can;

• use work equipment or other measures to prevent falls where they cannot avoidworking at height; and

• where they cannot eliminate the risk of a fall, use work equipment or other mea-sures to minimise the distance and consequences of a fall should one occur.

The Regulations include schedules giving requirements for existing places of workand means of access for work at height, collective fall prevention (eg guardrails andworking platforms), collective fall arrest (e.g. nets, airbags etc), personal fall protec-tion (e.g. work restraints, fall arrest and rope access) and ladders. See the Health andSafety Executive web site [5] for more information. The site gives Work at Height Solu-tions to provide good practice advice for people planning a task that involves work atheight. There is a list of solutions and a Frequently Asked Questions section. 1

2.16. OFF-CAMPUS WORK (DR JOACHIM ROSE) 25

2.16 Off-campus work (Dr Joachim Rose)

Postgraduate students or staff within the School of Physics and Astronomy may haveto work off-campus for some time period. For example to attend a conference or to usean external research facility. The health and safety rules and regulations still apply asthey would on campus.

• The off-campus work and the travel to and from the off-campus site may not sig-nificantly increase the risk. For example a conference trip within Europe, travel-ling by train or with a major airline. In such cases postgraduates or staff shouldindicate this on the Application for Approval for Leave of Absence Form 2.

• If either the proposed off-campus work itself or the necessary travel do lead toa significant increase in risk then a prior risk assessment is required. In thiscase the Application for Approval for Leave of Absence Form should reference anapproved risk assessment for the trip. For repeat visits, provided there havebeen no significant changes, it can be reasonable to refer to an earlier existingrisk assessment.

• There may be occasional cases where it is not reasonably practicable to carry outan advance detailed analysis of each hazard. In such cases the risk assessmentshould then describe the potential hazards as far as they are known, togetherwith the steps that will be taken to reduce the risks. For example, the person trav-elling may be sufficiently competent to respond appropriately to an unforeseensituation or he or she will receive suitable training by the external organisationprior to starting the off-campus work.

Undergraduates need to discuss the safety arrangements for off-campus work withthe project supervisor or module leader. The safety arrangements are then recordedin a form which is handed into the undergraduate office prior to the trip.

2.17 Software controlled systems (Dr Joachim Rose)

The data acquisition systems and instrument control systems in research labs andworkshops often contain processors and associated software. In the worst case even asimple malfunction, such as a false reading, may not only result in damage to equip-ment but also in major injury. Changes to either the operating system or the applica-tion software can have unintended or unforeseen consequences. For example a wellintended overnight remote modification of the operating system aimed at saving en-ergy by letting idle computers go to sleep can disable a vital control system thus lead-ing to a major incident. Hardware and software in research labs and workshop shouldtherefore be under the direct and full control of local staff who understand the poten-tial impact of configuration changes, who can carry out tests for correct behaviour andwho are able to handle and contain the impact of failure situations.

• Modifications to laboratory equipment, including any related related software,must only be carried out by the laboratory staff or the workshop staff unless byprior agreement or in response to a request by the laboratory manager or thehead of the workshop to involve staff (or contractors) which are external to thelaboratory or workshop.

http://www.physics.leeds.ac.uk/forms/index/absence-form


• Within research labs and workshops any mechanism for remote or automaticoperating system modification or application software upgrades should be dis-abled, unless the laboratory manager or head of workshop decides that it is de-sirable and safe to enable automatic or remote modification.

• Physical access to the equipment in a laboratory or workshop (as a supervisedvisitor) requires the prior permission of the laboratory manager or the head ofthe workshop. A procedure for the activity must be agreed and the safety impli-cations need to be discussed. A record of the authorisation by the laboratory ofworkshop should be kept.

• If there is a possible hazard then a prior risk assessment of the activity is needed,which then requires approval before the modifications are carried out.

• Any agreed work by IT support staff (or any other persons external to the lab-oratory or workshop) needs to be monitored and supervised by laboratory staffor workshop staff. Laboratory and workshop staff must be actively involved ata level that allows them to maintain a detailed understanding of the state of thesystem and of the potential impact of any changes.

• As far as practical safety critical systems should be isolated from any networkor protected against incoming connections, unless the lab manager or head ofworkshop decides that it is desirable and safe to enable network access.

• If there is no other practical alternative then accounts for persons external tothe laboratory or workshop, for example IT support staff, can be created. Theseaccounts must never used to circumvent or disable the access restrictions forlaboratory or workshop equipment.

Similar arrangements apply to systems and software outside the laboratory or work-shop, for example in office environments, if they are used to develop safety criticalsoftware, are used as an external monitor or as a remote control station or if they arein some other way safety critical.

Chemistry Laboratories

The two chemistry laboratories (8.331 and 8.312) have over 50 combined registeredusers - from simple sample cleaning to complex organic synthesis. It is essential thatall users are aware of what they and other users are doing. All users must undergoan induction into the lab, before use is authorised. The Laboratories are run by DrBen Johnson, who is responsible for the day-to-day running of the laboratories andis empowered to ensure that users follow the correct procedures. Training about thecorrect procedures is given during the lab induction. Regular laboratory users may berequired to undertake additional general laboratory duties.

A.1 Undergraduate Physicists doing Chemistry (Dr Ben Johnson)

Undergraduates are not permitted to work alone in the chemistry labs. Any processbeing undertaken by undergraduates in the lab must have a COSHH assessment andbe limited to low hazard processes. Further guidance must be sought from the labmanager prior to work commencing.

A.2 Implementation of COSHH in the Chemistry Lab (Dr Ben Johnson)

In both Chemistry Labs, COSHH forms are not kept adjacent to the experiment inprogress where pieces of paper could constitute a fire risk! Instead the COSHH formsreferring to experiments currently in progress are to be kept in the marked red fileclearly displayed near the laboratory door.

A.3 Lab Usage Guidelines (Dr Ben Johnson)

Usage guidelines, recommendations etc. for the lab are constantly evolving, so pleasecheck the lab’s website to keep up to date with these: http://www.mnp.leeds.ac.uk/biophyschemlab.

Radiation safety

B.1 Radiation Protection Supervisor (Dr Peter Hine)

The School Radiation Protection Supervisors are: Dr Peter Hine, Ext:36648(RadiationSources and X-rays). In his absence Dr Mannan Ali, Ext:33833should be consulted.

B.2 Controlled areas (Dr Mannan Ali)

The following areas in the School are designated as controlled areas, access to whichis restricted to workers operating under a written system of work. Most of the con-trolled areas are regions of space in the vicinity of X-ray Generators and are not tobe considered as controlled areas when the generators are switched off or if the highvoltage supply to the appropriate X-ray tube is clearly off.

Room 8.237 - X-ray LaboratoryThe interiors of each of the three enclosures mounted on the X-ray generators.

These enclosures contain the X-ray tube, tube shield and associated equipment andthe doors are interlocked with the generator and shutter controller.

Rooms 8.10, 8.30 - First and Second Year LaboratoryThe interiors of the clear Perspex housing which serve as safety shields for the Tel-

x-ometer X-ray generators in the First Year Laboratory. When the mains supply tothese units is interrupted the interior of the enclosure is no longer a Controlled Area.

B.3 Rules for undergraduate work with ionising radiation (Dr Peter Hine)

For the attention of undergraduate students carrying out experiments with ionisingradiation

All workers with ionising radiations have the obligation:-

1. to be aware of the hazards associated with such radiation

2. to follow rigorously any procedures and practices specified in the manuscript forthe conduct of a particular experiment

Accompanying the experiment which you have been given to perform you willfind listed certain procedures which have been devised for the safe handling of radionuclides or for the safe operation of machine sources of radiation. You MUST NOT de-viate from these procedures. If any problem arises in connection with the proceduresyou MUST consult a demonstrator or the laboratory technician before proceeding.

B.4 Rules for X-ray generators in room 8-237 (Dr Mannan Ali)

For the attention of users of the X-ray generators in room 8.237.

31

32 APPENDIX B. RADIATION SAFETY

New users and anybody who is unfamiliar with a particular piece of equipmentor technique involving use of one of the X-ray generators must consult one of thetwo persons named below in order to obtain appropriate instruction. “Second hand”instruction is potentially hazardous and must not be sought. The enclosures on theX-ray generators are interlocked to prevent access to the beam. No attempt shouldbe made to defeat these interlocks at any time. If any problems arise which requireaccess to the X-ray beam or if the equipment malfunctions or if instruction is requiredDr Mannan Ali, Ext:33833, should be approached:

B.4.1 Work inside interlocked enclosures

General Protocol for working inside the interlocked enclosures mounted on the X-raygenerators in Room 8.237,

Personnel: These procedures may only be carried out by Dr Mannan Ali.

1. Before commencing work possible hazards should first be considered. If there isany doubt then one of the above persons should be consulted at an early stage.

2. Use the override key to disable the interlocks and warn other persons in the roomthat you are doing so.

3. Install as much temporary shielding as you can around the beam in the area inwhich you are working.

4. Switch on the generator at minimum power and open the shutter.

5. Check the radiation field in the area where your hands will be. If the radiation issignificantly above general background close the shutter and check/increase/repositionthe temporary shielding. Open the shutter again and check the radiation field.

6. If the radiation field is now satisfactory increase the beam power to the workingpower which should be the minimum consistent with being able to carry out thework.

7. Check the radiation field again. If it is satisfactory proceed with the work. If itis not satisfactory rearrange the temporary shielding until it is. 8. Remove theoverride key to a safe place as soon as the procedure is completed.

B.4.2 Protocol for diffractometers adjustment

Protocol for making adjustments to one of the diffractometers on generator C in room8.237 when the other diffractometer is in use Personnel: All radiation workers Nor-mally the diffractometers are used with all of the interlocked doors closed. It is per-missible, however, to make adjustments to the superstructures on one of the diffrac-tometers whilst the other is in use. Care should be taken to avoid radiation exposurein these circumstances.

1. Make sure that the shutter on the equipment you are working on is clearly closed.

2. Open the appropriate interlocked door.

3. Mount a freestanding shield immediately in front of the beam exit aperture.

4. Check, using the minimonitor, the radiation field at all points where you will putyour hands inside the half of the enclosure in which you are working.

B.4. RULES FOR X-RAY GENERATORS IN ROOM 8-237 (DR MANNAN ALI) 33

5. If the radiation level is significantly higher than background level either (a) con-sult SRPS or Dr Mannan Ali or (b) wait until the other diffractometer is not inuse and proceed with the generator switched off.

6. If the radiation is only slightly above background levels outside the enclosureyou can proceed.

7. If you can proceed, carry out any operations as swiftly as possible.

8. When you have finished make a positive check that the shutter is still closedbefore you remove any temporary shielding.

9. Close the interlocked door.

B.4.3 Protocol for the Wide Angle Camera

Protocol for the Alignment of the Wide Angle Camera on Generator B in Room 8-237Personnel: These procedures may only be carried out by Dr Mannan Ali.

1. Appropriate personal dosimeters must always be worn during this operation.



4. Check the radiation field in the area where your hands will be. If the radiationis significantly above general background, place temporary shielding in positionto reduce it.

5. Mount a mirror behind the fluorescent screen so that the rear of the screen canbe seen clearly from outside the enclosure.

6. Using just sufficient beam power to observe the beam spot observe the spot onthe screen and adjust the camera mount using the two positioning screws on thetube shield mounting block. to maximise the beam intensity. Be very careful notto move your hand towards the film holder. Keep it as far as possible from thecollimator exit in order to prevent inadvertent exposure. If any movement of thecamera other than a slight realignment is required switch off the generator andcheck the whole assembly for correct mechanical alignment.

7. Remove the override key to a safe place as soon as the procedure is completed.

B.4.4 Protocol for the Pole Figure Goniometer

Protocol for the Alignment of the Pole Figure Goniometer on Generator B in Room8.237.

Personnel: These procedures may only be carried out by Dr Mannan Ali.


2. Before switching on the generator mount a fluorescent screen in the sample holderposition.


34 APPENDIX B. RADIATION SAFETY

4. Check the radiation field in the area where your hands will be. If the radiationis significantly above general background, place temporary shielding in positionto reduce it.

5. Using just sufficient beam power to observe the beam spot watch the spot on thescreen and adjust the tube shield position using the two socket head adjustingscrews on the base of the tube shield mounting column to maximise the beamintensity. Be very careful only to position your hands in the vicinity of the ad-justing screws and do not lean into the cabinet. If any adjustment other thana slight realignment is required switch off the generator and check the wholeassembly for correct mechanical alignment.

6. Remove the override key to a safe place as soon as the procedure is completed.N.B. A plastic divider panel should always be positioned between Airedale andWharfedale. Interlock key must not be on display Dr Mannan Ali to keep it in asafe place. Red light to be positioned centrally at back.

Appendix C

Portable appliance test guidelines

C.1 Testing of new or existing portable equipment (Mr Richard Oliver)

All portable electrical equipment needs to be tested for electrical safety.

1. All new electrical or electronic items powered from the mains MUST be taken toElectronics Workshop before first use to be electrical safety tested. At this pointeach item receives an unique appliance number.

2. When the new item is brought for PAT testing a job request form should be filledin including the owner’s name and the location where it is used - Testing all itemsas they enter the department in Electronics Workshop maintains that all itemshave at least been tested once before being used. An appropriate test interval canbe allocated to that item and the serial numbers of the items can be recorded foraudit purposes on the database.

3. Existing items in the department (many of which have been through the PATtesting procedure several times from the early 1990s) will be tested according tothe policy outlined below and merged into the new system.

C.2 Policy for repeat tests of existing portable equipment (Mr Richard Oliver)

Detachable power cords should have their own appliance number, consisting of theappliance number of the item it connects to + C and should be tested separately. Thetest sticker being placed on the plug face for ease of checking.

Review of items that have passed PAT test several times, obtained from PATS databaseto allow for an increased test interval. Analysing the PATS database indicates that nonew PCs failed PAT test and they did not fail subsequent tests. As these items arenot really ’portable’ and most of the monitors are now LCD without the internal highvoltage of a CRT screen, a 5-year interval would be most appropriate.

The analysis shows a very low failure rate for instruments and general electricalequipment. There should be a sliding scale of test intervals as the test results mountfor that equipment. A 2-year interval applied for new instruments, moving to 4 yearsfor successive passes.

The analysis shows that items of heavy usage, e.g. heaters, kettles, distributionboards, soldering irons etc., should be tested every year, as cables become damagedsockets become damaged and strain relief fail. These should remain at a 1-year inter-val.

The teaching lab areas currently operates a sliding scale test interval up to 2 yearsfor test instruments. As this equipment is operated by undergraduates it is suggested

Table C.1: Testing intervals and colour coding

that a 2-year interval be the maximum interval for safety reasons. The PCs can havean extended interval.

Attended two PAT testing courses run by different companies neither highlightedand problems with our testing strategy.

The testing intervals and colour coding would be as outlined below in Table C.1.The Pass sticker contains the appliance number, initials of test person, date tested

and next test date.These proposals require approval by faculty and university safety officers.Two new PAT testing kits have been purchased (tester and accessories) to provide

4 modern and 2 old testers for general use.Nominated persons from each group, along with technical staff have attend train-

ing courses. Nominated persons from each group to assist the students in ensuringrooms are fully tested.

The ’Duty Officer’ regarding any issues from the test results and visual inspections,should be a member of Electronics Workshop.

To make it easier for the user of the PAT tester, to know the most appropriate testfor a given item and to carry out additional tests the names and settings of some of thestandard pre installed tests have been changed.
