GFG Alliance Whyalla ISOLATION FOR PERSONAL PROTECTION QP29.20 Revision 15 Safety 1.0 PURPOSE Ensure isolation of energy source is carried out to prevent injury to personnel caused by: The accidental or unexpected start-up of machinery or movement of materials during servicing, maintaining or any other interaction. Contact with or exposure to hazardous energy. This procedure describes the minimum requirements for the control of potentially damaging energy (and substances) to provide personnel protection. 2.0 SCOPE Applies to all people working (where isolation is required for personal protection) on SIMEC Mining and Liberty OneSteel Steelwork s sites. When personnel would be endangered by the unexpected start-up of machinery or release of stored energy. When personnel are required to bypass any guard, interlock or other safety device. When personnel are required to place any part of their body into an area where work is being performed. This procedure does not cover operations (e.g., hot-tap, fault finding electrical testing or calibration) where equipment shutdown is impossible, provided that special equipment and/or procedures are used that will ensure proven effective personal protection. This document covers responsibilities, training, procedures, audits, variations, nonconformance and hardware. The major components of the isolation system are that it is: - planned - locked - verified, and - carried out by appropriately authorised personnel. 3.0 REFERENCES GFG Alliance Australia Code of Practice - Isolation MM.29.04 Safety Management Systems Manual QP 02.03 Event Recorder / Audit Database and Issues Management QP 29.06 Incident Investigation and Reporting QP 29.11 Plant Safety Management and Inspections QP 29.13 Safety Risk Management QP 29.21 Warning Tag Regulations QP 29.28 Health and Safety Training WI 29.541 Management Review of Disciplinary Action Arising From Safety Breaches FORM29.005 Variation Approval Form FORM29.006 Operational Access Approval Form FORM29.007 Isolation Code Variation Approval Form Any PRINTED copies of this procedure are UNCONTROLLED Page: 1 of 13

GFG Alliance Whyalla ISOLATION FOR PERSONAL PROTECTION QP29.20 Revision 15 Safety 5.4 Isolation Procedures and Permits Isolation procedures and permits for personal protection shall be developed, documented and used for isolation of potentially damaging energy. The procedure and/or permit shall clearly state the scope, purpose, authorisation, rules, and techniques to be used for the isolation of potentially damaging energy. Attachment 1 outlines the necessary features of any isolation procedure. Written isolation procedures and/or permits are required for all complex isolations. 5.5 Isolation Practice 5.5.1 Group Isolation Practice A written procedure and/or permit shall exist before group isolation can be used. Group isolation may be used if many persons are involved, the isolation is in place for more than one shift, many isolation points are involved or as deemed necessary by the responsible manager. The personnel setting up the isolation must be provided with the steps necessary to be protected from stored energy. The permit shall reference the pertinent work procedures. When there is a sequence of isolations required to do a job safely a work procedure shall explain the stored energies and what personnel who are setting up the isolation must do to be safe when setting up the isolation. A greater level of detail should be included in the work procedure generally more so than on the isolation permit. If any doubt exists then a safe system of work should be completed. If a permit is one in a sequence then this must be clearly indicated. For example if isolating the counter balance on a conveyor is the second isolation of three for removing a conveyor belt. An isolating person shall place the isolators in the safe position and lock them with equipment locks and central isolation board identification. An isolating person shall verify that the isolation is effective. The yellow equipment lock will be attached to a multi-lock device to indicate that the isolation has been verified. The completed Isolation Permit and Equipment List is displayed on the Central Isolation Board. Where isolation boundaries cross normal access and egress areas the boundary of the isolation must be marked. If this causes major difficulties then a diagram of the isolated area must be displayed at all access and egress points so that a person following normal practices could not unknowingly enter an area controlled by the isolation. The diagram must also be kept on the isolation board with the permit. The keys of each equipment lock shall be placed in the central isolation board by the isolation leader affixing the group lock. Green group lock keys shall be stored in designated labelled key cupboards or similar controlled container for access by authorised persons only. Then and only then shall individuals lock the central isolation board with their personal lock. Any PRINTED copies of this procedure are UNCONTROLLED Page: 8 of 13

GFG Alliance Whyalla ISOLATION FOR PERSONAL PROTECTION QP29.20 Revision 15 Safety Satellite central isolation boards may be set up: the isolation leader shall lock the master central isolation board with an equipment lock. the key of the equipment lock shall be placed in the satellite central isolation board and locked by the isolation leader affixing a group lock. then and only then shall individuals lock the satellite central isolation board with their personal locks. For more detail on Satellite Boards see Attachment 9, Section 5. 5.5.1.1 Use of an Isolation Checker In some circumstances, due to the risk or nature of a particular isolation, it may be deemed necessary by the Isolation Planner to have an independent Isolation Checker. Where this is the case the requirements and responsibilities of the Isolation Checker must be documented in the isolation procedure and/or permit. Using checkers is optional however when utilised they must be appropriately trained (trained to the same level as the isolating person) and must check the process of verification. The isolation planner will decide if a checker should be used and will provide a permit with the appropriate sign-off box. 5.5.2 Individual Isolation Practice An isolating person shall: Place the isolator in the safe position and lock with an equipment lock. This step is to ensure that the person conducting the verification has control over the isolator. It also demonstrates to others that the isolation has not yet been verified for individual isolation. If verification is immediate and visual, e.g. a knife switch or slip plate, then the multilock device may be fitted immediately. When the lock prevents the verification step being carried out, the verification step can be carried out without the yellow equipment lock in place provided that the isolating person is in total control of the isolator during the verification step. Verify the isolation is effective. Remove the equipment lock, fit a multilock device and lock with an equipment lock and isolating person identification. Yellow equipment lock keys shall be stored in designated labelled key cupboards or similar controlled container for access by authorised persons only. (When the isolation doesn t progress beyond the current shift, the Isolating Person can keep the yellow lock keys secure without the need for the keys to be placed in a designated key cupboard). Protected person lock each isolator with a personal lock on the multilock device, which has been locked with an equipment lock. 5.5.3 Contractor Yellow Equipment and Green Group locking Contractors can isolate individual isolations and group isolations when: The contracting isolating personnel are trained, competency assessed and authorised by the plant manager. The department keeps a register of authorised contractors and what plant the contractor can isolate. The department shall keep a record of the contractor s training assessment.

When the plant to be restored is not in the reverse order than an equipment restoration checklist must be used, see Attachment No. 12. 5.7 Removal of Locks An isolating person shall not remove any equipment lock from an isolator unless all personal locks are first removed. An isolation leader shall not remove a group lock from a central isolation board unless all other personal locks are first removed. Personnel shall only remove their own personal locks. Personal locks must be removed at the end of the person s shift or if the requirement for personal protection is no longer needed for the particular job/task. If a person is leaving the works they are required to remove their personal lock. NOTE: If removal of personal locks is required for other reasons, this shall be communicated via the A.T.W. and toolbox meetings at the commencement of the job. 5.8 Shift and Personnel changes The continuity of personal protection must be ensured during shift or personnel changes. The following steps shall be observed if changeover of the isolation leader is required using a group isolation procedure. The on-coming isolation leader shall be fully conversant with all aspects of the isolation. The on-coming isolation leader receives custody of the group lock key from the offgoing isolation leader. The on-coming isolation leader shall satisfy themselves of the integrity of the isolation. The on-coming isolation leader shall change the name in the isolation leaders position on the central isolation board. 5.9 Emergency Removal of Locks 5.9.1 Red Personal Locks and Individual Yellow Equipment Locks Where a person has failed to remove a personal lock or equipment lock the responsible manager may authorise the plant owner to remove the lock provided that all the following requirements are met: ensure that the plant is safe to operate. all practical efforts have been made to locate the individual and have them remove their lock. all practical efforts have been made to contact the person to ensure that the person could not return to the job and be endangered by the equipment being operated.
