- Lockout/Tagout is a method of keeping equipment from being set in motion and endangering workers.
- Lockout/Tagout is necessary whenever you are performing service or maintenance around any machine where you could be injured by unexpected startup or movement. The most common situations that require Lockout/Tagout are:
a. when you remove or bypass a guard or other safety device
b. when you place any part of your body where it could be caught by moving machinery
c. when using electrical circuits
- Whether the power switch is on or off, energy could be present in equipment.
- Stored energy poses special problems. Be aware of the power source, i.e. hydraulic pressure, steam, electric charge, etc. Dissipate all residual energy prior to working.
- Energy controls are applied according to a six step procedure:
a. Preparation for shutdown
b. Equipment shutdown
c. Equipment isolation
d. Application of Lockout/Tagout devices
e. Control of stored energy
f. Equipment isolation verification
Removal of Lockout/Tagout
- Prior to removing Lockout/Tagout devices, determine if the equipment is safe to operate by removing all tools and verifying that the system is fully assembled.
- The Lockout/Tagout devices should be removed by the person who put them on, except in an emergency.
- When the worker who applied a lock is not present to remove the lock, it can be removed only in an emergency, and only under the direction of the supervisor.
- Follow the manufacturers checklist to re-energize the system.
- If an outside contractor or other outside worker is performing service or maintenance, they should coordinate their activities with the Electrical Department or other appropriate department.
- See to it that Lockout/Tagout protection remains in effect when switching shifts.
- Never remove a lock until you are absolutely sure that it is completely safe to do so.
