5 Requirements 5.1 Determination and Evaluation of Confined Spaces

Confined space determinations and evaluations shall be conducted by a team of competent personnel who will consider and evaluate all possible items of plant that could be classified as a confined space. Evaluations shall be performed using DR010904 Confined Space Determination and Evaluation Form.

Once a space has been defined as a Confined Space the evaluation team in conjunction with AS 2865 and DR033304 Confined Space Hazard Identification Guide complete DR033302 Confined Space Identification and Risk Analysis Worksheet to identify risks and apply appropriate controls.

5.2 Reclassification of a Confined Space For a confined space to be reclassified as a non-confined space, it needs to have undergone sufficient change in structure or usage to eliminate (without the need for risk control measures) all possible sources of inherent hazards that define a confined space. Any changes to a confined space would have to be such that a subsequent risk assessment would determine that it no longer meets the criteria for a confined space (Clause 2.4.6 AS 2865-2009).

Reclassification of Confined Spaces requires consultation with the General Manager Health & Safety and approval of the Registered Manager.

5.3 Confined Space Register A Confined Space Register shall be maintained by the responsible Area Manager. The register shall contain the following information:

• A description of the unique identification number of each space;

• A copy of the completed DR033302 Confined Space Identification & Risk Analysis Worksheet for each space;

• A copy of the Isolations Checklist for each space (if required);

• A copy of the DR028987 Confined Space Rescue Plan (if required);

• A copy of DR047957 Ventilation Plan (where required).

5.4 Hazard Identification In and Around Confined Spaces All hazards associated with the space, or with work required to be performed on or inside the space, shall be identified, risk assessed and appropriate control




measures implemented to eliminate, or otherwise minimise, the risk posed by those hazards. In the absence of a suitable Safe Work Instruction, hazard identification shall occur by creating a task based JHEA.

The Confined Space Identification & Risk Analysis Worksheet shall be reviewed as part of this risk assessment process. Where changes to the space and inherent risks are identified, these shall be updated as required.

5.5 Ventilation Plan Requirements Confined spaces may contain atmospheres that are flammable, toxic or whose oxygen level has been depleted or enriched.

Although a single rule or group of rules is unlikely to cover all of the ventilation requirements applicable to confined spaces, the general objectives of ventilation in confined spaces are to:

• remove contaminated air (flammable or toxic) from the space and maintain safe concentration levels in terms of exposure standards (ES) or lower explosive limit (LEL);

• provide fresh and breathable air inside the space;

• create a more comfortable environment inside the space.

Ventilation requirements to enter and work in confined spaces depend on the nature of the space, its content, and the operations that will be performed inside the space.

The CPM Hygiene department must be contacted to determine if a ventilation plan is required if the confined space:

• has an atmosphere containing or likely to contain potentially harmful levels of contaminant;

• the space normally contains a potentially harmful contaminant;

• potentially harmful contaminants or work activities such as hot work, painting or use of adhesives are being introduced into the space;

• has or is likely to have an unsafe oxygen level; or

• is of a nature or is likely to be of a nature that could contribute to a person in the space being overwhelmed by an unsafe atmosphere or contaminant.

The Ventilation Officer or appointed delegate is responsible for completing DR047957 CPM Confined Space Ventilation Plan.

If a Ventilation Plan is required, the Hygiene department are to be given a minimum of 48 hours’ notice of intended works. Requests are to be made using DR048671 Ventilation Request Form.




5.6 Signage and Tagging All confined spaces shall be identified, evaluated and signs erected at the entry points denoting that a permit is required prior to entry. Signage must comply with AS 1319 -1994 Safety Signs for the Occupational Environment. Please refer to Appendix A.

Ventilation equipment shall be clearly identified and tagged to prevent unauthorised operation to comply with AS 2865–2009 Confined spaces clause 3.4.20 Control of Mechanical Ventilation Equipment.

5.7 Isolation Prior to entering a confined space all potentially hazardous energies, as identified in the Confined Space Identification and Risk Analysis Worksheet attached to the space, JHEA or other relevant documentation, shall be positively isolated where it is possible to do so. Where it is not possible to do so, a separate procedure shall be developed and appropriate control measures implemented to minimise the risk to personnel.

An Authorised Isolator (electrical/mechanical) will carry out all isolations and apply permit tags and locks in accordance with the Permit to Work process.

5.8 Lighting and Other Portable Electrical Equipment For all work in a confined space, lighting and portable electrical equipment shall comply with provisions of AS 2865-2009, clauses 3.4.44 to 3.4.47.

Temporarily installed lighting should have an emergency backup power supply.

Portable electrical equipment

Portable electrical equipment should be either:

• connected, individually or collectively to an earth-free, protected extra low voltage supply from an isolating transformer;

• protected through a RCD located outside the space.

Where there is potential for combustibles, portable equipment should be intrinsically safe.




Supply cables

Portable electric equipment should be fitted with a flexible supply cable not inferior to a heavy duty type. The cable should be located, suspended or guarded to minimise accidental damage.

Double – insulated tools

Where available, it is recommended that double–insulated electrical tools be used with the appropriated IP rating.

5.9 Atmospheric Testing Gas testing should be carried out in accordance to DR033453 CPM Confined Space Atmospheric Testing Instruction. No person shall enter a confined space until an Authorised Gas Tester has verified that:

• The confined space contains safe levels of oxygen (between 19.5 and 23.5%);

• The concentration of any flammable contaminant in the atmosphere of the space is below 5% of its LEL.

A competent Authorised Gas Tester shall carry out atmospheric testing of the confined space at a time and frequency as identified on the Confined Space Entry Certificate. A person entering a confined space to perform atmospheric testing/monitoring shall have a Confined Space Entry Certificate to do so and comply with the requirements of this procedure.

Gas testing shall occur at least 30 minutes after mechanical ventilation has been isolated and not greater than 30 minutes before first entry of the confined space. Where confined spaces have been cleared of all personnel for greater than a 30 minute period, testing must re-occur prior to re-entry.

Where entry certificates remain open, atmospheric testing must occur at intervals not greater than 12 hours.

5.10 Cleaning, Purging and Venting A safe atmosphere can be achieved within the confined space using methods such as cleaning, purging and ventilation. Where contaminants are present within a confined space, they are to be cleaned out prior to entry by the use of a suitable purging agent that is not pure oxygen or gas mixtures with oxygen content greater than 21%. Confined space ventilation should be by natural, forced or mechanical methods to establish and maintain a safe atmosphere.

Where activities inside a confined space introduce toxic fumes (i.e. welding, grinding, gluing) constant venting/purging of the atmosphere is required. Air drawn from fans need to be clean air upwind and 10m away from any generators/pumps.




Exhausted air must be expended into the atmosphere at a location where it does not present a risk to personnel in the vicinity.

Each department with ventilation fans must ensure they are kept secure (i.e. in the PTW Office) to prevent unauthorised or misuse. Fans are to be inspected and tested on a monthly basis to verify functional reliability.

NOTE: Information tags are to be placed on the power board connected to the ventilation fan(s) to prevent disconnection during confined space entry activities.

Where the atmosphere cannot meet the safe levels required, only competent persons with self-contained breathing apparatus or airline apparatus and emergency back-up can enter a confined space.

Atmospheric monitoring and testing shall be performed consistent with the hazards identified and in accordance with the Confined Space Atmospheric Testing Instruction.

5.11 Issuing of the Confined Space Entry Certificate A Confined Space Entry Certificate can only be issued by Authorised Permit Issuers.

CSE certificate will only be issued after the completion of:

(i) associated Permit to Work with JHEA / SWI;

(ii) First Response Rescue Plan;

(iii) a ventilation plan (if required as per section 5.5); and

(iv) atmospheric monitoring conducted by a competent person(s), for the work to be performed.

The JHEA, which is required for all Permits to Work authorised under the Confined Space Entry Certificate, shall consider:

• if the need to enter the space can be eliminated by performing the work from outside the space;

• the nature of the confined space;

• all hazards; and

• effective control measures to minimise the risk of hazards (e.g. cleaning, purging, atmospheric testing, breathing apparatus, ventilation, barricading, communication equipment etc.).

The Confined Space Entry Certificate shall be prominently displayed at the entry point to the confined space for the duration of the work and shall indicate:

• the time and date the permit is valid;




• the name of the person in control of the work (Permit Holder);

• special precautions required for the safe entry and control of the work;

• the date, time and signature of any person(s) entering and leaving the confined space;

• the date, time and signature of the Standby Person (Sentry);

• the results of atmospheric testing;

• a register for all Permits to Work issued for working inside the space.

Associated documentation that shall be kept at all times with the Confined Space Entry Certificate includes:

• First Response Rescue Plan;

• Ventilation plan (when required);

• Atmospheric Monitoring Sheet and CSE Entry/Exit log (where ongoing or periodic monitoring is required).

• Permits to Work with their relevant JHEA / SWI and certificate(s).

Where associated paperwork identifies additional control measures to those already stipulated for general entry to the space i.e. increased gas test frequency, temperature monitoring, or hearing protection, then the need for additional controls must be indicated in the Confined Space Entry Certificate .

Confined Space Entry Certificates may be transferred from one Permit Holder to another during the course of its validity. The person accepting the permit / certificate as the Permit Holder accepts all the responsibilities and accountabilities to ensure that the conditions of the permit / certificates are met, that hazards are constantly assessed and control measures are in place and effective.

If there is more than one access point to the confined space, the other access points shall be sign posted and barricaded to prevent involuntary and unauthorised entry but allows emergency egress.

5.12 Revalidation / Relinquishment Re-validation at beginning of shift or task commencement, and relinquishment at end of shift or task, is required for all Confined Space Entry Certificates.

The Permit Holder shall ensure that the workplace copy of the Permit to work and the Confined Space Entry Certificate is relinquished to the Permit Issuer upon completion of works for the shift. Relinquishment must not occur until:

• all personnel have left the confined space and all openings of the confined space are barricaded and sign posted to prevent unauthorised entry;




• all personnel have removed their personal locks and danger tags from the Group Lock Box;

• all personnel have signed off the entry/exit log; and

• the work site has been left in a clean and safe condition.

At the commencement of shift the Permit Holder shall re-validate the Permit to Work and Confined Space Entry Certificate by signing the re-validation section of the original and duplicate copies.

5.13 Safety Equipment All safety equipment identified in the JHEA / SWI as being required shall be provided, including equipment for:

• personal protection;

• communication equipment (i.e. two-way radios, horns, phone);

• emergencies, including rescue;

• first aid; and

• fire suppression.

Safety equipment shall be appropriate for the work and maintained in good condition.

When the risk assessment determines that fall protection equipment is the best control measure, fall restraint equipment/techniques shall be the first choice, unless the potential for a free fall cannot be eliminated, in which case fall arrest equipment shall be used.

5.14 First Response Rescue Appropriate First Response Rescue with first aid procedures / provisions and emergency response shall be planned, established and rehearsed as per the Confined Space First Response Rescue Plan for the specific confined space. All First Response Rescue Plans shall be developed in consultation with on-site Emergency Services.

The work group intending to work in the confined space must obtain the relevant First Response Rescue Plan from the Permit to Work Office and complete the following prior to the issue and acceptance of the Confined Space Permit to Work:

• task description;

• exclusion zone(s);

• non ERT and personnel equipment requirements – particular to the specific confined space;




• initial emergency response – i.e. what will the workgroup team members do to remove any person from a confined space in the event of an emergency;

• ensure a sketch or photo of the confined space showing the controlled entry exit locations;

• the nominated ERT pickup point;

• site emergency contact phone numbers;

• communication.

The responsible work group Supervisor shall review and approve the completed Plan. In cases of response by Emergency Services, those persons involved in the response shall be made aware of the conditions in the confined space prior to any entry:

• all rescue equipment must be readily available and regularly serviced for use by competently trained emergency response personnel;

• all persons who may be involved in any way with emergency response associated with a confined space, shall be made aware that:

- well-planned and well-rehearsed emergency response procedures are essential and shall be followed at all times; and

- openings for access and egress to and from a confined space should conform to the relevant Australian Standards to permit rescue of all persons who may enter the confined space.

6 Control, Responsibility and Accountability The generic accountabilities and responsibilities of the various parties have already been indicated, however it is essential that the specific responsibilities are set out very clear to ensure no misinterpretation or confusion when applying the procedure. The specific responsibilities of the parties are listed:

6.3 Authorised Gas Tester Authorised Gas Testers (AGT) must be trained in confined space gas testing to a nationally recognised competency standard. The candidate must complete Gas Test Atmospheres:-Theory and Practical Assessment which includes three (3) different practical tests within the business area. On successful completion of the test the area manager will be able to appoint the candidate. See DR035106 PTW Appointment Form. The appointed AGT must be able to demonstrate ongoing compliance to the gas test of atmospheres in accordance to this procedure and AS 2865 -2009.

An Authorised Gas Tester is accountable for ensuring that:

• gas testing is conducted in accordance with the CPM Confined Space Atmospheric Testing Instruction;

• gas testing equipment is calibrated and in good working order as per OEM instructions;

• analysis and monitoring of the confined space for an irrespirable atmosphere is performed prior to any entry;

• they record the initial atmosphere testing results on the Confined Space Entry Certificate and any on-going measurements are entered on the Atmospheric Monitoring Record Sheet.

6.4 Permit Holder Permit Holders are accountable for workers safety by ensuring that:




• they have viewed and understand the Permit to Work, Confined Space Entry Certificate and supporting documents;

• after reviewing the Confined Space Identification and Risk Analysis, participate in the development of, and understand the risk controls in, the SWI / JHEA(s) with consideration given for undertaking the activity within the confined space;

• the SWI / JHEA(s) and all relevant documents (i.e. SDS, rescue plans) are reviewed by all persons entering the confined space;

• ensure all conditions of the Confined Space Entry Certificate are adequate and additional controls identified in the Permit to Work are implemented prior to confined space entry;

• at the end of shift, or if otherwise required, ensure all personnel are clear of the confined space and relinquish the Permit to Work to the Permit Issuer;

• upon completion of the work within the space, the Permit Holder closes the Permit to Work off in the Confined Space Entry Certificate.

6.5 Ventilation Officer The registered Ventilation Officer (VO) is responsible for making the final decision as to whether a ventilation plan is required prior to entry of a confined space. This decision is made with full consideration of potential chemical contaminants, welding fume and oxygen levels arising from both the local environment and the proposed works. The VO also calculates the required air flow and atmospheric turnover within any given confined space, to provide the appropriate level of safety for any workers entering that space. This is recorded in the ventilation plan.

6.6 Confined Space Entrants All individuals entering the space are accountable for their own safety by ensuring that:

• they are trained in confined space entry to a nationally recognised competency standard and hold a current VOC in accordance with DR022088 Verification of Competency Procedure;

• they participate in conducting, or read and understand, the JHEA prior to entry as well as any applicable SWI’s, rescue plans, or SDS’s

• those individuals entering a confined space are responsible for ensuring they familiarise themselves with all applicable instructions for the task to be undertaken within the confined space;




• if a Safe Work Instruction (SWI) fails to completely cover every aspect of the task to be undertaken within the confined space, then a task based risk assessment (JHEA) must be conducted for the intended task prior to entry;

• if the scope of work or conditions change from those present in the JHEA / SWI, they stop work and conduct a re-evaluation analysis;

• the conditions of entry on the Confined Space Entry Certificate and the SWI/JHEA must be discussed in detail with the Permit Holder prior to the individual(s) signing onto the permit and commencing work within the confined space;

• they fully comply with all control measures identified in the JHEA / SWI and Confined Space Entry Certificate;

• they sign on to the entry/exit log prior to entry and when leaving the space;

• the individual(s), while working within the confined space, must monitor changes to conditions of the space, changes in the tasks being performed and, if required, vacate the space and update the JHEA. It may be necessary to have the Sentry update and revalidate the permit before re-entry is allowed; and

• upon completion of the work the individual(s) exit the space and sign off the permit.

7 Competency / Training Requirements All CPM and contractor personnel required to work in confined space or conduct Gas testing shall hold a current National Unit of Competency. This competency shall be renewed through a registered training organisation every five (5) years. An on-site validation of competency shall be undertaken every 2 ½ years with CPM Training department to maintain competency

The minimum training competency of any person entering a confined space includes:

• RIIWHS202D – Enter and Work in Confined Spaces

• MSMWHS217 – Gas Test Atmospheres (Applies only to Authorised and Appointed Gas Testers)

All relevant training documentation is to be available for audit by designated CPM personnel. CPM employees are to provide the documentation to the CPM Training department prior to undertaking any confined space entry related tasks.

Only persons trained in confined space entry and this procedure are to be appointed and nominated to act as Permit Issuers and Permit Holders where




required. Nominated Permit Holders and Standby Persons must be competent through knowledge, experience and training to be able to effectively:

• initiate site emergency response procedures; • operate communication equipment as applicable; • operate and monitor any safety plant or equipment that may be required; • monitor any changes to hazards or risks within the confined space and take

appropriate action where any changes may result in a risk to health and safety.

Ongoing training and verification of competency shall be in alignment with DR022088 Verification of Competency Procedure.

8 Implementation The following points are general requirements when working within, or in association of a confined space:

• a Confined Space Entry Certificate is valid for a maximum of 30 days;

• only persons trained and competent in confined space entry, issue and acceptance of Confined Space Entry Certificates and this procedure are to be nominated as Permit Issuers and/or Permit Holders;

• only registered Permit Issuers are to raise and issue a Confined Space Entry Certificate;

• only registered Authorised Gas Testers are to conduct atmospheric testing and monitoring;

• only persons trained and competent in safe work in confined spaces shall sign onto DR033058 Atmospheric monitoring and CSE Entry / Exit log, and work within or on a confined space;

• only persons suitably trained and assessed as competent are to undertake the duties and responsibilities of a confined space Standby Person (Sentry);

• in the event of an emergency situation arising within a confined space, the Confined Space Entry Certificate is automatically cancelled;

• during an emergency situation within or on a confined space, the emergency response personnel and emergency response initiators are exempt from the requirements of this procedure. However, access to the confined space shall not be undertaken without the correct RPE being worn, minimising the risk of exposure to potential contaminates within the space.




9 Confined Space Entry Process 9.1 Details

The location or area, plant, equipment and space name are recorded in this field. It is important to provide as much detail in the field as possible to avoid confusion in an emergency situation.

Work cannot commence until a JHEA / SWI has been completed for the intended task to be performed within the confined space. The JHEA / SWI must be attached to the Confined Space Entry Certificate for all entrants to review prior to entry.

9.2 Communication The most suitable and practical form(s) of communicating an emergency and initiation of evacuation from the confined space is identified. The general means of communication between the Standby Person and the Permit Holder / work group is also identified.

9.3 Gas Testing and Monitoring With consideration of the risks identified in the associated JHEA (s) or SWI(s) requirements for gas testing frequency are identified.

Gas testing monitors and docks will be operated, calibrated and maintained as per OEM recommendations and manuals. Calibration and bump testing records will maintained with in a register by the departments.

9.4 Measurement of Atmosphere This section is to be completed by the Authorised Gas Tester (AGT). Prior to all confined space entries, the space must be tested to ensure a safe atmosphere. The AGT may re-assess the need for continuous monitoring, conditions of entry as well as the need and frequency of re-testing based on initial test results. Once the AGT has determined the atmosphere is safe, they must record the gas meter identification number, the AGTs name, signature and date against the initial measurements.

9.5 Control Measures This section lists the minimum required control measures as determined by the Permit Issuer and the Permit Holder in conjunction with the requirements from the JHEA.




The aim of this section is to allow the Permit Issuer to determine which of the listed controls are necessary for a particular confined space entry. If a control measure has been identified then the Permit Issuer is responsible for ensuring that the control measure is in place prior to entry as well as informing the Permit Holder and the Standby Person of this requirement.

9.6 Permit Duties Acceptance by Permit Holder Following review of all submitted documentation including Confined Space Determination and Evaluation Form, First Response Rescue Plan, Ventilation Plan, JHEA(s) or SWI(s) and Confined Space Entry Certificate, the authorised Permit Holder acknowledges his/her duties and responsibilities by signing and dating this section

9.7 Permit Re-Authorisation The Permit Issuer records the validity period of the permit in this section. The maximum time a Confined Space Entry Certificate is valid for is 30 days. However, the permit must be relinquished and revalidated at the end of every shift (not the length of one shift, but rather until the shift in which the entry started is over).

10 Change of Standby Person / Sentry This section is used when the Standby Person / Sentry can no longer carry out the duties and responsibilities of the position within a normal shift. In which case, another suitably trained and competent Standby Person / Sentry must assume the duties and responsibilities and ensure the conditions of the permit are still valid.

It is not necessary to cancel the permit and raise a new permit within the same shift, but it is essential that the incoming Standby Person is aware of all conditions and control measures before transfer occurs.

The permit should be re-validated whenever it becomes evident that the duration of work will involve one of the following:

• A change of the person responsible for the direct control of the work in a confined space;

• A significant break in work continuity; or

• A significant change in risk, e.g. atmosphere, or work to be performed.

NOTE: The Confined Space Entry Certificate must stay at the point of entry of the confined space for the duration of the occupancy and shall not be removed during the transfer of the permit. In these situations the Permit Holder must be advised and attend the work area to sign authority to transfer the permit.




The permit cannot be transferred across shifts. If the work is to continue after a change of shift, the permit must be relinquished and re-validated.

11 Cancellation of Confined Space Entry Certificate The Confined Space Entry Certificate can only be cancelled by the Permit Issuer after verifying that:

• All persons are out of the space and signed off the permit;

• All tools and equipment have been removed;

• It is safe to return the space/equipment back to normal operations;

• DR033060 Confined Space Final Inspection has been completed.

12 Reporting / Recording and Auditing Reporting and recording is mainly completed through the Confined Space Entry Certificate as outlined under section 8. All parties involved are required to fill in all the detail in applicable sections of the certificate, and sign off in the sections as required. The document is not complete until it has been cancelled and signed off. These completed documents shall be retained in accordance with AS 2865:2009.

Training records of CPM personnel shall be kept on a training database for every employee, and will be retained for the term of the employee’s employment period. A hard copy of the actual documentation generated during the assessment after training, will also be kept on a personal file for this purpose.

Random audits shall be carried out on confined space work to ensure compliance with this procedure. Any non-compliance shall be reported to the Area Manager or Superintendent for further investigation and follow-up. Training records shall be checked randomly to ensure currency of training and will also be triggered through the CPM training database.

13 Records Management Once the certificate has been approved, the Permit Issuer will hand to the Permit Holder the workplace copy of the Confined Space Entry Certificate along with any other Permit to Work and supporting documents.

The Permit Holder will take the Confined Space Entry Certificate and other supporting documents to the Permit to Work users and walk through the requirements.

The Permit Holders will sign onto the work permit at the start of the job and off at the completion of the job.




On completion of the job, the Permit Holder takes all documents back to the Permit Issuer and the permit(s) are signed off.

The Confined Space Entry Certificate and supporting documents shall be retained on file for audits and statutory purposes. The Permit Issuer is responsible for maintaining the file.

All permits / certificates shall be retained in accordance with DR008575 CPM HS Document and Record Control Procedure requirements.
