Lockout Powered By Docstoc
					Lockout/tagout procedures are necessary when:
       1. Performing service or maintenance on any equipment where unexpected start-up or release of stored energy (electric,
            mechanical, thermal, potential, steam, pneumatic, hydraulic, chemical) could cause injury.

       2. Removing a guard or other safety device, or placing your body where it could be caught or trapped by moving machinery
            during normal operation.


Lockout/tagout procedures apply to all Company operations, including academic and service units. Individuals who have been
designated by their supervisors and who have received training will follow these procedures. Supervisors will be responsible for the
training and for implementing this procedure. Training will be given whenever there is a change in job assignment, a change in
machines, equipment or process that presents a new hazard, and will be followed up every 2 years.


Procedures

       1. Equipment shutdown and isolation
               o     Notify affected employees of equipment that is to be locked out before and after it is locked out, and the reason for
                    the lockout.

               o     Identify all the sources of energy, the hazards of that energy and how the energy can be controlled.

               o     Identify all switches, controls, power sources to isolate the system

               o     Shut down the equipment by normal stopping procedures

               o     Disconnect and isolate the equipment from all its sources of energy (including secondary supplies).

       2. Equipment specification
            Locks: See sample or equivalent fulfilling the following requirements:

               o     Keyed differently, this should be verified upon receipt of the locks

               o     Made by a reputable manufacturer

               o     Standardized in at least colour, shape or size

               o     Durable

               o     Capable of withstanding the environments to which they are exposed

               o     Cannot be forcibly removed without bolt cutters

               o     Will only be used for lockout/tagout

            Tags: See sample or equivalent fulfilling the following requirements:

               o     Standardized in print and format and in at least colour, shape or size

               o     Durable

               o     Will warn against hazardous conditions if the machine or equipment is energized

               o     Indicate:

                                The name of the person attaching the tag
                    The name of the person authorized to removed the tag

                    The reason the tag was attached

                    The department responsible for the work

                    Time and date the tag was attached

   Other Equipment

     o   Test equipment (volt meter)

     o   Lockout hasps for multiple users

     o   Valve lockout devices

     o   Light switch lockout devices

     o   Circuit breaker lockout devices

     o   Fuse lockouts, plug lockouts

     o   Wall switch lockouts

     o   Chains for valves

3. Lockout/tagout application
     o   Sign out Lockout/Tagout equipment from the Lockout/Tagout Station

     o   Inspect all equipment visually before every use. Report damaged equipment to group leader, supervisor or
         designated person

     o   Insert lock and tag (with work order, if applicable)

     o   Double check your steps

4. Control of stored energy
     o   Bleed off residual pressure in steam, compressed air, hydraulic or other systems checking that moving parts have
         stopped turning

     o   Blank pipe flanges

     o   Install ground wires to discharge electrical capacitors

     o   Secure or block elevated equipment that may fall due to gravity

5. Equipment isolation and verification
     o   After ensuring that no one is exposed, operate the start button to ensure the equipment will not operate and return
         the equipment to off or neutral position.

     o   Test the equipment with a volt meter to verity de-energization or identify other sources of energy

     o   Remove guards or covers as necessary

     o   Perform work

     o   Verify isolation periodically until maintenance, service and repairs are completed

6. Removal of locks and tags
     o   When work is completed, remove tools from work area and reinstall guards or covers

     o   Ensure the system is fully assembled

     o   Check area and do a head count to ensure no one is exposed. Warn employees to stay clear

     o   Remove locks and tags

     o   Restore power and run the equipment

     o   Notify affected employees that work is completed and that equipment is returned to operation

     o   Record of all systems to be rendered inoperable will be kept

7. Group lockouts
     o   Each person working on the same piece of equipment will not be protected unless he/she attaches his/her won locks
         and tags. Locks and tags will not be shared.

     o   If an employee forgets to remove his/her lock after completion of the work, he/she will be paged or reached by
         telephone to discuss the status of the work and of the equipment. If they both decide the work is completed, the
         supervisor will check the equipment and cut the lock. If the employee cannot be reached, the supervisor will
         thoroughly check the equipment and cut off the lock of the work is done and the equipment is safe.

8. Troubleshooting, testing or positioning of machines, equipment or components
     o   Clear the machines of tools and materials

     o   Remove affected employees from the machine or equipment area

     o   Remove the lockout/tagout devices

     o   Energize and proceed with testing

     o   De-energize all systems and reapply energy control measures to continue servicing and maintenance
