1 OBJECTIVE The purpose of the PHPA Isolation & Tagging Procedure is to ensure the safety of all personnel on the PHPA sites from injury caused by an uncontrolled release of energy. The procedures are designed to comply with Statutory Regulations and with PHPA Health and Safety Standards. This purpose shall be achieved by ensuring that where practicable Positive Isolation is used for the protection of personnel working under a system of isolation on PHPA sites. Where positive isolation is not practicable, operational controls that permit controlled movement when a positive isolation is not in place must be included within a Detailed Work Instruction (DWI) or Safe Work Method Statement (SWMS). This shall be approved in writing from the Registered Mine Manager for that specific task. Should a DWI or SWMS not exist for that task, a Job Hazard Analysis (JHA) shall be written and approved by the Registered Mine Manager or deputy before commencing that task. 2 SCOPE The PHPA Isolation & Tagging Procedures apply to all operations on PHPA work sites that involve work tasks with a risk of a hazardous release of energy (e.g. electrical, mechanical, chemical energy). This includes all in-loading and out-loading conveyor systems at Utah Bulk Loading Facility and Berth 01. This procedure outlines the methods to be used when performing isolations on plant and equipment to prevent accidental release of energy sources whilst personnel are performing work on plant and equipment. A key requirement in preventing accidental energy release is to ensure that where practicable all isolation points are positively isolated. This will be achieved by ensuring that: Electrical equipment is proven to be de-energised and the isolation points locked. Mechanical Isolations are proven de-energised, systems bled, pressure released and locked in the case of valves and restraining devices and an air gap provided or the use of spades or blanks in the case of pipelines. The system will require: Training and assessment to ensure personnel are competent to carry out the tasks required by these procedures. The use of padlocks to maintain the integrity of the isolation/s at the specified isolation point/s. The use of tags with padlocks to identify ownership and control. Notes: Where guards are not fitted, the lanyard pull cable is the limit at which any part of the body or implement in contact with the body can approach the conveyor, whether moving idle, unless the conveyor has been positively isolated. Isolations involving High Voltage shall only be carried out by appointed persons, and may require specifically designed switching procedures which differ from the procedures referred to in this and related documents. Please refer to PHPA PR M003 High Voltage Access Procedure. Page 6 of 50

7 GENERAL SAFETY The primary objective is to provide personal protection to persons working on plant and equipment. A secondary consideration is the prevention of damage to equipment and environment. The procedure applies equally to servicing, repairs, inspections, testing and adjustments, cleaning and pre-start checks. In all of these instances the PHPA Isolation and Tagging Procedure shall be followed. REMEMBER: FAILURE TO FOLLOW THE PROCEDURE COULD RESULT IN DEATH, DISABLEMENT, PERSONAL INJURY OR DAMAGE. FOR THAT REASON, UNAUTHORISED REMOVAL OF TAGS OR OTHER VIOLATIONS OF THE ISOLATION AND TAGGING PROCEDURE MAY RESULT IN DISCIPLINARY ACTION. This procedure is required to protect individuals or groups of personnel from physical injury or through contact with or exposure to the following types of energies: Chemical (corrosives, gases, toxic materials) Electricity Radiation (induction sources, lasers) Mechanical (e.g. kinetic) Pressure Gravitational Thermal Stored Energy This procedure is to be applied in circumstances where: Personnel are required to work on or within contact distance of any of the above energies Where there is a potential for contact and harm to people, equipment or the environment. The PHPA Isolation and Tagging Procedure applies to all mobile and fixed plant and equipment at all operations. Once the equipment has been isolated, the equipment SHALL not be attempted to be started until: Each individual has removed their own Personal Danger tags and locks from all isolation points, lockbox or lockout stations. The isolation locks and tags have been removed by an authorised person. The isolation switch has been moved to the on position. Only authorised personnel will be allowed to isolate plant and equipment, a minimum competency of Minor Isolation Officer will enable personnel to isolate mobile or fixed plant. Isolation of energies may be established using the following methods: Breaking electrical circuits by using one of these three methods stated in section 12. Page 12 of 50
Note: Devices such as emergency stops, pull wire switches or any other devices associated with control systems shall not be used as primary approved isolation points. Closing valves in flow or delivery systems carrying pressure, gas, liquids, slurry, steam or venting to atmosphere to release stored pressure. Open valves in flow or delivery systems carrying pressure, gas, liquids, slurry, steam or venting to atmosphere to release stored pressure. Physically securing an object to control gravitational forces using pins, slings or chocks, belt clamps. 7.1 Competency to Perform Isolations Only persons, who have completed Isolation Officer Level of Isolation and Tagging training and have been assessed, deemed competent and authorised are able to perform isolations. Once trained, assessed and deemed competent, they shall be appointed in writing by the Nominated Person to undertake the duties of Isolation Officer in accordance with the PHPA Isolation & Tagging Procedure. 7.2 High Voltage Isolations for Electrical Access Refer to PR M003 High Voltage Access Procedure. No person shall make personal contact, either directly or through any conducting object with any high voltage conductor believed to be dead, unless the conductor has been effectively earthed and short-circuited and is complying with all the requirements of the High Voltage Switching Procedure. High Voltage apparatus, which is to be earthed and short-circuited, shall be proven to be dead and safe for earthing and short-circuited by use of equipment specifically designed for the purpose and used in accordance with the manufacturer s instructions.

PHPA personnel that are to be issued with a personal lockset and key shall first be trained in the Isolation and Tagging Procedure and pass the competencies for Minor Isolations at minimum. Personal Locks and Keys shall be issued to personnel by their Supervisor. A minimum of one personal lock to be issued to each person. A maximum of a lock set of 6 is required to be issued to personnel authorised to conduct Minor Isolations as per section 11.2 A person shall not use another person s lock(s) and key. No person shall place another person s lock No person shall remove another person s lock unless authorised. Refer section 11 All the locks on a lock set shall use the same key Only one key to be issued per lockset Personal locks and key shall be marked with a unique identification number A personal lock holder shall gain permission by making positive contact with Permit Holder or Isolation officer prior to attaching their personal lock and tag to isolation points. A personal lock holder shall not isolate plant and/or equipment, except for appointed Minor Isolation Officers as per section 11.2 A record of Personal Lock Holders shall be maintained in Training database and displayed in Maintenance Department. Records shall be kept with cross reference to the engraved identification code and the name of the person to whom the lockset was issued. 8.6 Yellow Isolation Locks Yellow Group Isolation Locks are used to lock the blue lock keys in the lockbox or lockout station under a Multi-Point or Major Isolation. One isolation key will be issued to each Isolation Officer. All isolation locks shall use the same key. Isolation lock key shall be marked with a unique identification number. Spare locks and keys shall be kept at a central location at each site. 8.7 Visitor Locks & Tags Visitor Locks and Tags may be issued where: A person who has not completed PHPA Isolation & Tagging training (visitor) and is required to lock onto an isolation point as a visitor. A personal lock holder that does not have possession of, or has not been issued their own lock, is required to lock onto an isolation point. Visitor locks shall be supplied by PHPA out of the visitor lock station and shall be issued to a visitor when deemed necessary by the Electrical Supervisor or Maintenance Superintendent. The visitor name, company, and contact number shall be recorded for return. Page 15 of 50
Visitors must be supervised by a person trained in the Isolation & Tagging Procedures. The supervisor of the visitor must witness the signature of the visitor s Personal Danger Tag and also be locked on to same point. 8.8 Record Keeping The following records pertaining this procedure are to be maintained at each site / location: Request for Isolation Isolation Statement Isolation Permit HV Switching Procedures used for isolation of plant Records are to be retained as per the PHPA PR ICT002 Recordkeeping Procedure. The following records pertaining to authorised personnel are to be maintained in the Mines Record Book: Statutory Letters of Appointment detailing site authorisation of Isolation Officers Statutory Letters of Appointment detailing site authorisation of High Voltage Operators / Assistants for the purpose of isolations The following records are to be kept in the PHPA safety management & training system (MYOSH): Record of all incidents and accidents related to the use of the Isolation and Tagging Procedure Training competencies and completion date Page 16 of 50
9 TAGS The use of tags is considered an administrative control and as such only provides limited protection to people and plant; therefore in all cases a physical isolation must be used in conjunction with a tag to prevent the accidental activation of an isolation point. 9.1 Personal Danger Tags Any person required to work on the equipment must place their clearly identified personal lock and tag on a hasp located on the isolation point or lock box. Remember, the main isolation point Shall Be turned and locked to the off position. The isolation should be tested and proven prior to the commencement of work by testing for absence of electrical power or stored energy. A Personal Danger Tag is for single use only and must be destroyed on completion of task. Do not assume that it is isolated - Confirm that it is isolated! The Personal Danger Tag and lock are designed to give personal protection and to highlight that the employee/s whose name appears on the Personal Danger Tag are engaged in carrying out tasks to the tagged equipment and could be at risk if the machine were to be started or moved. 9.1.1 Contractor Personnel All contractors and visitors working on PHPA sites shall conduct isolations in accordance with this procedure. Personnel shall also follow this procedure in relation to tag use. All contract personnel must place their personal lock and Personnel Danger Tag on the isolation point whilst in the presence of the Task Supervisor. All Personal Danger Tag Reminder stubs found on the bottom section of the tag shall be handed to the Task Supervisor for that task/work group prior to commencing task/work. This will confirm that contractor personnel have: 1. Completed the Personal Danger Tag correctly 2. Locked on to the correct lockbox and associated Isolation Permit for the task 3. Ensured confirmation of task completion during the lock off process Where a contractor or visitor has any queries or uncertainty when undertaking tasks within this procedure, they shall refer to their Task Supervisor or delegate from PHPA. Page 17 of 50
9.1.2 Attaching the Tag The person attaching the tag must completely fill the tag with the following information: Name & company of person placing tag The classification/department the person works for The date that the tag was placed The equipment / plant the tag was placed on Contact number Work order / job number if applicable Signature Page 18 of 50
It is important to clearly identify the exact piece of equipment that the tag and lock was placed on to allow identification of those personnel working on the plant. NOTE: Each and every person working on the job must place their own Personal Danger Tag / Personal Lock before the job commences only after the isolation has been tested and proven effective. Once placed it must remain in place for the duration that the person is on the job. 9.1.3 Removing the Tag No person shall remove another person s Personal Danger Tag. Only the person who signs and attaches the Personal Danger Tag can remove it. If a Personal Danger Tag has been left on the equipment at the end of the shift then that person will be contacted to return to site in their own time to remove their Personal Danger Tag. If that person cannot be contacted or is in an unfit state to return to site or is off on R/R then the approved tag removal procedure will be instigated (as per section 11.1). YOUR Personal Danger tag and lock are to be removed from the equipment by only you on completion of the task or at the end of the shift. Page 19 of 50
9.2 Isolation Tags The Isolation Tag Indicates equipment has been isolated by an Isolation Officer. Any item of equipment or machinery marked with an Isolation Tag shall not be operated. The equipment must be in an Isolated position, thereby removing energy from the circuit. A hasp is to be placed on the isolation point and a completed Isolation Tag with an Isolation Lock shall be placed on the hasp. 9.2.1 Attaching the Tag The Isolation Officer must print the following information on the tag: Isolation number Lockbox The date that the tag was placed How the isolation was confirmed Page 20 of 50
The equipment owner or area supervisor must be notified as soon as possible if the equipment has been fixed to ensure that the tag can be removed and the plant reinstated. NOTE: Anyone conducting repairs on plant or equipment will be required to place their own Personal Danger tag and lock on the hasp or corresponding lock box before commencing work. If the repair is not complete within the shift or they are called away, they must remove their Personal Danger tag/lock. The Permit Holder shall ensure the Isolation Tag & lock remains and if repairs are not complete, an Out of Service tag shall be attached to the isolation point and plant equipment controls. Page 21 of 50
9.3 Out of Service Tags The Out of Service Tag allows for faulty, unsafe or permanently disabled equipment to be taken out of service to prevent further use or damage to the equipment. Any item of equipment or machinery marked with an Out of Service Tag shall not be operated or used except for the direct purpose of repair by an authorised person. The isolation switch on the equipment must be switched to the off position, thereby removing power to the circuit. A completed yellow Out of Service Tag must then be placed on the isolation point. If it is a power tool or other hand tools or apparatus or equipment that is not energised, the Out of Service Tag should be securely attached to the defective device. Page 22 of 50
9.3.1 Attaching the tag The following information shall be printed on the tag: Equipment name Name of person placing tag Classification of fault/reason for out of service The date that the tag was placed It is important to clearly identify the exact reason for placing the tag to allow proper analysis and rectification of the problem. The equipment owner or area supervisor must be notified as soon as possible of the condition and the reason it has been placed Out of Service. Once a piece of equipment has been tagged Out of Service to conduct repairs, the equipment must be isolated in accordance with this procedure. An Out Of Service Tag shall REMAIN attached to the device or main isolation point of the equipment during the time that the repairs or servicing and inspection are being carried out. This ensures that even when left unattended, the unsafe condition of the equipment is communicated readily to any person. Anyone can place an Out of Service Tag on faulty plant/equipment; however only authorised personnel or an authorised delegate can remove it. Only a qualified person in the maintenance or repair of that piece of equipment may then remove the tag once repairs are complete. Page 23 of 50
9.4 Information Tag In some instances instruction needs to be given about a specific piece of equipment, barricading of a designated area. In these instances an information tag shall be used. The tag shall be placed by personnel to communicate a message about the conditions of entry, status of equipment or any other relevant information. In the event an Information Tag has been placed all personnel shall read the information. 9.4.1 Attaching the tag The person attaching the tag must completely fill out the tag with the following information: Print their name The department the person works for The date and the time that the tag was placed The equipment / plant the tag was placed on Page 24 of 50
9.4.2 Removal of Information Tag: Removal of Information Tags shall only occur once the information is no longer relevant Prior to removal of tag contact the area owner Any person may remove the tag once the steps above are completed Page 25 of 50
