- Lockout/Tagout is a method
of keeping equipment from being set in motion and endangering
- 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:
when you remove or bypass
a guard or other safety device
when you place any part
of your body where it could be caught by moving machinery
when using electrical circuits
- Whether the power switch is on or off, energy could be present
- 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:
Preparation for shutdown
Application of Lockout/Tagout devices
Control of stored energy
Equipment isolation verification
- 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
- Never remove a lock until
you are absolutely sure that it is completely safe to do so.
