LOCKOUT SYSTEM AND POLICIES

1 LOCKOUT SYSTEM AND POLICIES Lockout System Purpose Employees health and safety takes top priority. Isolating hazardous energy to prevent sudden and unexpected energisation of machines, equipment, and processes is an important component in our safety, health and environment programme and, accordingly, the lockout system will be used by authorised personnel only. Lockout System Scope This lockout system will apply to all our facilities whenever employees or contractors are working on our premises at activities where the release of hazardous energy is a possibility. Lockout procedures will be used whenever machines, equipment, or processes are being serviced, maintained, or repaired. Lockout procedures shall also be followed when an employee must by-pass a machine safe-guard to service or repair a machine. Lockout System Work Rules When service or maintenance is being performed on a machine or equipment, Zero Energy State/Zero Mechanical State/lockout procedures will be enforced. Machines shall be at a Zero Energy State when cleaning, oiling, or adjusting is being done near unguarded and/or any moving parts of the machine or process materials. Lockout requirements must be followed. Equipment Lockout Capabilities Equipment, machines, or processes that must be locked out during servicing, repair or maintenance must have energy isolating controls that affect lockout devices in the following situations.. whenever:- - New equipment/machines/processes are purchased and installed. - Existing equipment is significantly modified, repaired, renovated, or replaced. - Energy isolating devices are repaired or added to equipment. Procedures An inventory of all written lockout procedures will be maintained and updated regularly. Appropriate personnel shall be authorised to monitor, update and apply the lockout system and procedure. Sequence of Lockout Procedure (Zero Energy State) Inform relevant personnel that the Zero Energy State process is being instituted. If the equipment is operating, shut it down by the normal stopping procedure. Disconnect all sources of energy so they are inoperative or isolated from the equipment to be worked on. Stored energy sources such as capacitors, hydraulic pressure, air pressure, water, gas, steam, etc. must be dissipated so as to prevent any machine movement. Where this cannot be accomplished, lockout devices must be used so Zero Energy State can be attained.

2 Lockout all energy isolating devices (electrical disconnects, air valves, water valves, etc.) with an approved lockout device. Attempt to operate the energy isolating devices to insure that Zero Energy State can be maintained. After assuring no personnel are exposed, try the start controls to make certain the equipment will not operate. Periodic Inspection The purpose of the lockout system inspection is to ensure that the standards of the lockout procedure are followed without deviation. Recommendations to improve procedures shall be submitted at any time to the Risk Management Committee for review and acceptance. All lockout incidences will be investigated immediately and reported on at the quarterly Risk Management Committee meetings. Training and Communication Lockout is a way of life, not just a skill. Consequently, an appropriate level of lockout training will be provided to all relevant personnel. Training records will be maintained and retained for reference purposes. Contractors/Outside Sources Outside contractors must comply with our lockout procedure/system. To ensure compliance, training will be provided to contractors and records maintained and retained accordingly. Enforcement The lockout system and procedures will be enforced and any employee and/or contractor who intentionally fail to follow the lockout procedure/system will face disciplinary action i.e. this in terms of a violation of Safety, Health and Environmental rules and regulations. Contractors will be barred from the premises for failure to follow lockout procedures.

3 LOCKOUT PROCEDURE No repair work, non-visual inspection, adjustment, cleaning, servicing or lubrication may be undertaken on apparatus which is coupled to an electrical, mechanical, pneumatic, hydraulic or any other power source unless it has been isolated by a competent person in the appropriate trade and locked out by means of the standard calliper(s)/hasps and lock(s) provided. ELECTRICAL LOCKOUT 1. Advise responsible person, and/or operator associated with the machine that repairs or maintenance is to be done. 2. Locks only (without calliper or without lock out danger tags/boards) may not be used as they cannot be identified. 3. Where facilities do not exist to fit lockouts, danger notices and name tags must be properly secured to isolated equipment and if applicable, the fuses must be removed and circuit disconnected by registered wireman. 4. The Electrical Foreman at Facilities Management is to be notified if facilities do not exist to fit lockouts so that he may make necessary arrangements to rectify this situation. 5. Set the relevant isolator to the OFF position. 6. Attach your warning board to your numbered padlock, and lock the isolating switch in the OFF position. 7. Before commencing work, test and make sure the machine is isolated and cannot be switched on. 8. Where work is carried out on one piece of equipment by more than one person, each person shall also place his lock and calliper to isolate that piece of equipment. If the equipment will only accept one lock, others must lock their callipers onto the first calliper. 9. The only person permitted to remove the lockout, danger tag or warning board after completing work on the equipment is the person who placed it. 10. Any person intending to set a machine in motion shall, before doing so, take all reasonable precautions to ensure that no other person is in the act of repairing, cleaning, oiling, adjusting or otherwise working on, or dangerously close to, such machine or machines. 11. The last person, whose lock and warning board is remaining on the isolating switch, shall be the person responsible for handing the machine back to the operator in a safe working condition. 12. It is an offence for any unauthorized person to remove, damage or deface any lockout, danger tag or warning board.

4 13. A signed register shall be kept by the Electrician Foreman of each lock, calliper and danger tag or warning board issued, together with a copy of this procedure Shall ensure that all new equipment is provided with lockout facilities. 15. Numbered padlocks and warning boards are obtainable through Estates. 16. The Electrical Foreman is responsible for all H.T. switching. NO H.T. switching is permitted at any time without the Electrical Foreman s written permission. 17. Any shock and/or electrical fire incident must be reported immediately to the Electrical Foreman and Risk Management Services. I acknowledge having received and understood the standing instruction on the University of KwaZulu-Natal lockout system. Name: Signature:.. Padlock No.: Date Issued:.

5 LOCKOUT PROCEDURE No repair work, non-visual inspection, adjustment, cleaning, servicing or lubrication may be undertaken on apparatus which is coupled to an electrical, mechanical, pneumatic, hydraulic or any other power source unless it has been isolated by a competent person in the appropriate trade and locked out by means of the standard calliper(s)/hasps and lock(s) provided.
