VARIANTS

3.1.1 GENERAL When planning the installation of Emergency Safety Showers,Eyebaths and Eye/Facewash equipment the advice of a qualifiedfirst-aid person or medical advisor should be sought to establish themost suitable choice of equipment, location and procedures for first-aid and decontamination.

There is a possibility with some dangerous substances thatdrenching with water could accelerate a chemical reaction. Water

temperature may also have a bearing on the effectiveness of theequipment chosen. Consideration should also be made for disabledpersons, including people in wheelchairs or people with special

requirements due to their height.In all circumstances installation procedures should be in accordancewith proper plumbing practices. Multiple models with different typesof activation should be avoided wherever possible.

Emergency Shower, Eyebath and Eye/Facewash equipment isnot a substitute for proper primary protective devices. As adefence against splashing injurious liquids and flying solidparticles, workers should wear Personal Protective Equipment

(PPE) as needed, which includes eye protection, face protectionand protective clothing.

LOCATION

For Emergency Safety Shower, Eyebath or Eye/Facewashequipment to work effectively when needed, it must be installedproperly and in the correct location. Such equipment should beinstalled within 10 seconds reach if an accident occurs; no closerthan 3 metres or further than 15 metres.The nature, severity and environment of the hazard should beconsidered in determining the maximum allowable unobstructeddistance. For hazards involving strong acids or caustics suchequipment must be immediately adjacent to the hazard and outsidethe most likely spray paths.Emergency Shower, Eyebath and Eye/Facewash units should be

located in a prominent position on the same level as the hazard andthe path of travel shall be free from obstructions such as heavy traffic

or doorways that may prevent the immediate use of the equipment. Ifthere is a doorway in the path of travel, it must not be possible to lock orlatch the door against the direction of travel and the swing of the doormust also be in the direction of travel of the exposed person.The area around and underneath the shower should provide good

drainage, especially if there is a possibility of the water freezing.Consideration should be given to the location of equipment sensitive to

heavy deluges of water or diluted chemicals, in particular electricalequipment. The work areas beneath elevated showers should also beconsidered in this regard.

When equipment is located indoors waste water must be contained forsubsequent safe disposal or there must be adequate drainage.Furthermore, procedures must be in place for clearing away residuewaste water after the use of this equipment.

Walk-on Panel type foot controls or Foot Treadles must be installed sothat loose objects or gravel cannot obstruct their operation.Where there is a possibility of freezing, equipment shall be suitablyprotected or alternatively a unit specifically designed to operate in such

conditions shall be installed. When units are installed outdoors in very hotclimates, they should be self -draining, or insulated from the effects ofoverheating caused by solar radiation. Emergency Shower, Eyebath andEye/Facewash water temperatures must never exceed 38.6°C or drop

below 10°C.

VISIBILITY

All units should be clearly labelled with a pictogram sign to EC Standard92/58/EEC (or International equivalent when outside the EC) and the signshould be positioned so that it is highly visible within the area served bythe equipment. Also, wherever possible, green/white stripes/hatching orgreen lights should be used to help identify the Emergency Shower,Eyebath and Eye/Facewash position, and the area under the unit shouldbe well lit at all times and the operating mechanism must be clearly

visible.

height of 208mm-244cm above the level on which the user stands.Thebaseplate is 460mm square with 4 x 17mm diameter holes for fixing boltson 305mm x 305mm centres as shown on the General ArrangementDrawing.

Wall mounted showers should be fixed so that the nozzles are at a heightof 208-244cm above the level on which the user stands.

3.1.3 WATER SUPPLY

Emergency Shower, Eyebath and Eye/Facewash units should befed from a potable water supply (drinking water or water of similarquality) and where necessary a non-return check valve should be

fitted to the supply pipe feeding the unit.The use of a long supply run should be avoided, especially where itrequires heating to prevent freezing or where it can be heated updue to the climatic conditions.The supply pipe should have at least the same diameter as the inlet

pipe on the equipment (even larger if long lengths of pipe are beingused to feed this equipment and especially if only low waterpressures are available).

Where more than one unit is fed from the same water supply thecapacity should be such that all units should be operable at thesame time without impeded performance. Furthermore, nopermanent or temporary connections shall be made to the watersupply that can affect the flow rate or pressure such that they dropbelow the recommended minimum.Tests must be carried out following installation to check the watersupply pressure cannot drop below the recommended minimumwhen other demands are made on it.

Where a high unregulated pressure is experienced the pressure

must be monitored to ensure that it does not exceed therecommended maximum. If the water pressure exceeds themanufacturers recommended maximum a pressure reducing valveshould be fitted within the supply line.

For first-aid treatment of casualties that have been involved inaccidents with certain speciality chemicals it may be recommendedthat additives be added to the water flow.

The maximum supply pressure should not exceed 6 bar g. If it is possible

for the supply water pressure to exceed 6 bar g then a pressure reducingvalve should be fitted in the supply pipe.

3.1.4 WATER SUPPLY PIPE MA TERIAL

The water supply pipe connected to the Emergency Shower, Eyebathand Eye/Facewash equipment must be either of the same material orof a material compatible with that of the unit to avoid corrosion.The use of dissimilar metals in the supply pipe should be avoided asthis could cause corrosion throughout the system. Cast iron or mildsteel pipe and fittings must not be used unless they are protectedwith a galvanised finish.

IMPORTANT NOTE: Isolation Valves should be fitted to the supply pipesin an accessible position for use during maintenance. The isolation valvesshould have locking mechanisms ‘to prevent unauthorised shutoff ‘ andshould be labelled accordingly with fixed permanent tags.

3.1.5 SHOWER EQUIPMENT

All Shower Nozzles should be removed during the initial flushingafter installation. The nozzle is unscrewed with a 36mm boxspanner (Part No.HTL15010), taking care not to displace the

internal diffuser. After flushing, the nozzle should be replaced usingsilicone grease. Shower roses (if fitted) should also be removedduring initial flushing.

Care must be taken not to over-tighten the nozzles and showerroses when replacing them.

EYE/FACEWASH EQUIPMENT • EXP-EH-5G/35G

Before operating the Eyebath for the first time, it is advisable toremove the spray head and flush the unit until the water is clean andfree from contamination and commissioning debris. The spray headshould then be replaced and a test should be carried out to verifyproper operation. Poor performance should be logged andimmediately reported to the management and rectified as soon aspossible.

EYEBATH EQUIPMENT• EXP-EH-5G/34G

• EXP-EH-5G/45GBefore operating the Eyebath for the first time, it is advisable to remove thespray head and flush the unit until the water is clean and free fromcontamination and commissioning debris. The spray head should then bereplaced and a test should be carried out to verify proper operation.

Poor performance should be logged and immediately reported to themanagement and rectified as soon as possible.

3.1.6 ELECTRICAL SUPPLY Where an Emergency Shower, Eyebath and Eye/Facewash unitrequires an electrical supply, either for heating, cooling or lighting,then the supply should conform to the requirements as detailed in thespecific instructions. Electrical equipment fitted to these units shouldbe supplied through a sensitive circuit breaker. An Earth LeakageCircuit Breaker (ELCB) is also highly recommended.Where an electrical supply is fitted it should be connected through a

lock-on switch to allow the electricity supply to be switched off formaintenance purposes only and should be labelled accordingly withfixed permanent tags.

The electrical components of the shower are wired into junctionboxes positioned as shown on the General Arrangement Drawing.Wiring diagrams and electrical loadings are provided with eachshower and are placed inside each junction box.

The cable entries on the junction box are suitable for M20 glands.Connections are live, neutral and earth, with a Single Phase supplyof either 50Hz or 60Hz, and of 110 or 240Volts (dependant oncustomer specifications, 240Volts being standard). The electrical

supply should be fitted with a circuit breaker rated 30mA 30ms.

Frost protection is by means of trace tape heating suitable for use in Non-Flameproof areas or areas designated as Zone 1 & 2, Gas Groups IIA, IIB& IIC, Temperature Class T3.Electrical power ratingGenerally 21Watts (or 42 Watts on -AH- variants),• EXP-EH-2G 12W • EXP-EH-5G/45G 36 W

• EXP-AH-5G/34G 45 W

Lights

(where optional lights are fitted)For Non-Flameproof indicator lights the power rating is 60Watts (max)

and the lights are fitted with bayonet type (B22d) lamp holders.Flameproof indicatorlights are rated at 100Watts (max) and have ES (E27) type lamp holders.Note : It is acceptable and common practice to fit low wattage energysaving lamps.

3.1.7 ALARMS (where fitted)

Alarms are generally fitted where personnel work in areas wherehazardous chemicals are present and in particular, wherecommunications may not be readily available. In all circumstancesthe nature of the hazard and its location should be evaluated andalarms should be considered for Emergency Shower, Eyebath and

Eye/Facewash equipment.

An alarm system (if fitted) should be activated when the Emergency

Shower, Eyebath or Eye/Facewash is operated.- The alarm shall be activated by a flow switch on the supply pipe orby a switch on the valve operating mechanism.

- The alarm shall sound on the unit as well as at a remote locationthat is attended during all working hours.

- The alarm shall show on a visual display board in the attendedlocation to identify the location of the emergency.

Alarm facilityMagnetically operated Proximity Switches are suitable for use with electricsupplies up to 250Volts, but it is generally preferable to use a low voltageon an intrinsically safe circuit. When two Proximity Switches are wired intoone junction box, they will normally be wired in parallel for ‘normally open’,

but could if required, be wired in series for ‘normally closed’. It is possibleto change the c ontacts to the normally closed position by rewiring the

junction box. A wiring diagram is supplied and can be found within the

junction box. Alternatively one is available from the Service Department at HUGHESSAFETY SHOWERS.

3.1.8 NOTESDuring the installation, if advice is required or further copies ofdrawings are needed, HUGHES SAFETY SHOWERS should becontacted immediately.

One week after commissioning, or once the plant is fully operational, theEmergency Shower, Eyebath and Eye/Facewash units should beoperated and checked for correct performance.

3.2.1 CODE OF PRACTICE

Chemical burnsRemove any contaminated clothing which is not stuck to theskin. Flush with plenty of clean, cool water for 10-15minutes. Apply a sterilised dressing to exposed, damagedskin and send the casualty to hospital.

Chemical in the eyeWash out the open eye continuously with clean, cool water for 10 to15 minutes.People with eye injuries should be sent to hospital with a pad over the eye.The first few seconds following an eye injury are often critical to minimising theseverity of the injury.

3.2.2 TRAINING

All employees that enter potentially hazardous areas in the

workplace must be trained in the use of EmergencyShowers, Eyebaths and Eye/Facewash equipment. Wheremultiple models with different types of activation are installedwithin the same working area additional training must becarried out covering the different methods of activation.Employees should also be aware of the exact location of allEmergency Shower, Eyebath and Eye/Facewash units and

a record of their training must be kept for a period of 5 years.

It is the responsibility of all employers to ensure that their employees are fully

trained with regard to Health and Safety at work. In the case where employeesmay be exposed to hazardous materials they shall be instructed as to the locationand proper use of Emergency Safety Showers, Eyebaths and FacewashFountains. Instructions for all emergency equipment shall be readily available andaccessible to personnel, whether or not they are employees of the company.

The most important factors are to 'know w here they are' and 'know how to use

them' .

3.2.3 'Know where they are' Initially, this involves showing trainees where the units arelocated in areas where they will work or may work in thefuture. In most instances this involves a limited number ofunits.

It is important to make each person aware of the position of emergency safetyequipment before starting work in any area. Furthermore, it is also important toremind current employees of their locations.

3.2.4 'Know how to use them'

It is most important that the affected part should be flushed

with plenty of clean cool water for 10 to15 minutes'.For highly toxic materials such as Hydrofluoric Acid it isrecommended that this be extended to ‘up to 30 minutes’dependant on individual circumstances.

During showering any contaminated clothing, which is notstuck to the skin, should be removed. This includes shoes,rings, watches, etc.

Medical advice must always be sought following any incidentinvolving dangerous chemicals or corrosive substances.Contaminated clothing must be bagged and disposed ofproperly.For washing of the eyes, training shall stipulate theimportance of holding the eyelids open and rolling theeyeballs so that flushing fluid will flow on all surfaces of theeyes and under the eyelids. Where contact lenses are being

worn these should be removed as quickly as possible duringthe flushing period.For facial splashes w here goggles have been worn andchemicals have not come into contact with the eyes, theface must be given an initial flushing with the goggles on toavoid washing chemicals into the eyes. After a few secondsthe goggles must be removed and both eyes and f ace

should be flushed for the full recommended duration. After using a plumbed-in Eyebath or Eye/Facewash unit it is

advisable to use an Eyebath Bottle filled with sterile salinesolution or medically accepted equivalent (this may be

carried out by the Company's qualified first-aid person or medical expert).

The shower is actuated by hand using a pull-down Hand Control. If the optional‘Walk-on’ Panel type foot control is fitted actuation is by foot pressure on thePanel. The foot control linkage is designed so that hand operation is alwaysavailable should this become necessary due to restrictions immobilizing the foot

control. Overhead shower nozzles are designed to give a ‘60º angle’ spray pattern.

Note : For any incident that involves chemicals in the eyes it is recommended that

the patient should always visit hospital to ensure that the first-aid treatment hasbeen successful.• EXP- EH-5G/10G

The shower is fitted with a horizontal body spray this operates simultaneously withthe overhead spray. The horizontal body spray nozzles have a ‘120º angle’

For optimum safety the valves remain open when operated,until such time as they are shut off manually.

Eye/Facewash Actuation• EXP-EH-5G/45G

The Facewash valve is actuated by simply pulling the lidforwards, or if an optional Foot Treadle is fitted, by pushingthis down with the foot. In the latter case, the linkage pulls

the lid clear of the facewash aerators and activates the valvesimultaneously. The two facewash diffusers can have theirflow rates adjusted together by means of the flow regulatorsituated on the right hand side of the facewash bowl.Note: This must not be closed after use.

Eye/Facewash Actuation• EXP-EH-5G/34G

The Facewash valve is actuated by simply pushing the handplate backwards, or if an optional Foot Treadle is fitted, bypushing this down with the foot.

The two facewash diffusers can have their flow rates adjusted together, by thethree pronged regulator, or separately, by means of the grub screws on each sideof the tee-piece in the centre of the facewash. A 4mm Allen key will be requiredfor this adjustment.Note: Ensure the aerators are clean prior to adjusting their flow rate.

Handheld Eyebath Actuation • EXP- EH-5G/35G

Eyebath actuation is either by simply pushing the hand plate backwards, or if anoptional Foot Treadle is fitted, by pushing this down with the foot. In the lattercase, the linkage activates the valve. The flow rate of the eyebath can becontrolled using the valve situated at the top of the flexible hose.Note: This must not be closed as the eyebath should be drained after use. Infreezing conditions it is good practice to leave the handheld eyebath hangingvertically.

3.2.5 SAFETY POSTERS AND TRAINING FILMS

Safety Posters or Safety Training Films are an importantway of training employees and visitors.Safety Posters should be displayed in prominent positions to

increase awareness in the workplace of the existence of thisequipment and to show how it is operated in case of anemergency.

Safety Training Films and Safety Posters are available from HUGHES SAFETYSHOWERS and these give clear and concise instructions as to the use of thisimportant life saving equipment.

3.3.1 SERVICING

All Emergency Shower, Eyebath and Eye/Facewash equipment should beserviced and cleaned regularly and at least every six months in order to

ensure proper operation.Records must be kept for a period of at least five years of theexaminations and tests carried out.

IMPORTANT NOTES:Maintenance and servicing must only be carried out when no otheractivities are being undertaken in the plant area

serviced by the Emergency Shower, Eyebath and Eye/Facewashequipment.

Only trained personnel with in-depth knowledge of this life-savingequipment should carry out maintenance and servicing. Full trainingavailable from the Service Department at HUGHES SAFETY

SHOWERS.

3.3.2 WATER QUALITY

Periodic analysis of the water quality within the Emergency Shower,Eyebath and Eye/Facewash equipment is recommended to ensure thereis no build up of harmful bacteria.

If necessary, following the test, the unit should be thoroughly cleanedand chlorinated/disinfected.

3.3.3 SHOWER MAINTENANCE

Shower NozzlesNo maintenance is normally necessary for the self -draining spray nozzles.Should the nozzles require cleaning or disinfecting they can be removed

by unscrewing them from the pipe using a 36mm box spanner (Part No.HTL15010). Shower roses (if fitted) should also be removed for cleaning.

After cleaning (disinfecting) the nozzles/roses should be replacedusing silicone grease.

Care must be taken not to over-tighten the nozzles and shower roseswhen replacing them

3.3.4 EYEBATH AND EYE/FACEWASH MAINTENANCEEyebath and Eye/Facewash units are fitted with fine mesh strainers toprevent the passage of any foreign bodies in the water. These strainersshould be cleaned regularly, particularly in the first 6 months of service as

there may be contamination of the water from dirt, jointing compounds,etc. which may have remained in the pipework following installation,despite the recommended flushing procedure.The Eyebath and/or Eye/Facewash nozzles should also be cleaned

regularly and the frequency will depend on the ambient conditions of theinstallation. In corrosive environments the Eyebath and Eye/Facewashdiffusers should be cleaned and where necessary replaced morefrequently.

After any maintenance work has been carried out on this equipment it isimperative that the Eyebath and Eye/Facewash units are given a full

operational test and that any flow regulator or volume control screws arere-adjusted to ensure optimum performance.

Eyebath and Facewash• EXP-EH-5G/34G

• EXP-EH-5G/35G• EXP-EH-5G/45G

It is recommended that the eyebath/facewash flow regulator isflushed out at regular intervals to remove any foreign bodies that

may have collected in the system. The eyebath/facewash should beoperated and the regulator should be adjusted to obtain maximumflow.

After this operation the eyebath/facewash diffusers should be

thoroughly cleaned.To clean the aerated diffusers, unscrew them from their holders andclean thoroughly (taking care not to lose the internal rubber washer).To refit, reverse the above operation - no sealants are required. This

procedure should be carried out at regular intervals.The flow regulator should then be re-adjusted to give the requiredflow through the eyebath/facewash.

To ensure hygienic operation, it is recommended that the aerators bereplaced every 6 months.Spare aerators can be obtained from HUGHES SAFETY SHOWERSor their local distributors.(M28 Aerator HEF05030M24 Aerator HEF05020)

3.3.5 FLUSHINGEmergency Shower, Eyebath and Eye/Facewash units should beactivated at least weekly to verify proper operation and ensure that anystored water is clean and fresh.It is not advisable to flush outdoor units in freezing weather as frozenwater on the ground may cause an accident. Special devices can be used

to catch the shower water and these can be used during the wintermonths to ensure continuity of shower flushing.

The duration of routine flushing should be sufficient to ensure boththe shower and water feed pipe are fully purged with clean freshpotable water; in practice this can mean flushing for up to severalminutes.

Recommended flushing instructions and periods should therefore beindividually indicated on each separate unit.

3.3.6 S HOWER AND EYEBATH CLEANING Under most site conditions it is necessary to periodically clean the outsideof the Emergency Shower, Eyebath and Eye/Facewash equipment. Thismust be carried out whenever the unit gets dirty.

Periodic cleaning clearly indicates that this important equipment is beinglooked after and is safe for use in cases of emergency.

IMPORTANT NOTE: Abrasives or solvents must not be used toclean the unit as this can damage the surface or affect the instructionstickers.

To comply with ATEX Directive 94/9/EC for electrical equipment,

use only a damp cloth for cleaning electrical devices and cables.

3.3.7 MAINTENANCE AND SERVICING OF ELECTRICAL EQUIPMENT

Thorough visual inspections should be carried out to check for externaldamage to the electrical units, their cables or the junction boxes. Shouldany part be found to be damaged, this must be reported and repaired orreplaced as soon as possible. A further test should be carried out toestablish that it functions as intended. Any additional electrical testsshould be carried out at the discretion of a qualified electrician. Fullinstructions should be obtained from HUGHES SAFETY SHOWERS. To

comply with ATEX requirements for electrical equipment, use only a dampcloth for cleaning electrical devices and cables.

Fault findingIf the shower’s frost protection heating system is not functioning aqualified electrician should investigate. An electrical continuity checkshould be made at the Junction Box. Should a fault be found with thetrace tape heating this may require replacement of the modularheated section. Please contact the Service Department at HUGHESSAFETY SHOWERS for further details.

3.3.8 IMPORTANT NOTES: During servicing and maintenance it is imperative that the temperature ofthe water delivered from the Emergency Safety Shower, Eyebath andEye/Facewash equipment is tested to ensure it never exceeds 35 oC ordrops below 10oC during the operating period of the unit. Temperatures

above 25oC can encourage the growth of organisms such as Legionellaand temperatures that are too low will discourage the use of theequipment for the full duration of 10-15 minutes as recommended.Temperatures of between 15oC and 25oC are therefore preferred for thesafe and effective use of this equipment.

3.3.9 OUT OF SERVICE PROCEDURE In the event that an Emergency Safety Shower, Eyebath or Eye/Facewashunit becomes temporarily out of service a standard procedure should befollowed.Place a sign on the unit indicating that it is ‘Out of Service’ .

Notify all individuals working in the area that the unit is out of service.

Prohibit or suspend any work where there is a significant possibilityof having an accident requiring the use of the unit.If work cannot be prohibited or suspended, a portable unit must beprovided to supply the initial wash only, after which it will be

necessary to move the person to a plumbed Emergency SafetyShower, Eyebath or Eye/Facewash unit to complete the 15 minutewash.

Note:Portable units are not acceptable as a long-term substitute forpermanent locations.
