Lock-out / tag-out

Lock-out/Tag-out procedures are safety measures, designed to prevent application
of power (energy) to the machine while it is being serviced.
The established procedures for the application of energy control (the lock-out or
tag-out procedures) shall cover the following elements and actions and shall be
done in the next mentioned sequence.
2.5.1

Lock-out / tag-out procedure

1. Notification.
Notify all affected employees that service or maintenance is required on the
machine and that the machine must be shut down and locked out.
2. Preparation for shutdown.
The machine may only be turned off by an authorized employee. Before turning it
off, the employee must know:
- The type and magnitude of the energy,
- The hazards of the energy to be controlled,
- The method or means to control the energy.
3. Shutdown.
If the machine is in operation, shut it down by the normal shut down procedure.
Refer to section Switch off.
4. Machine isolation.
Isolate the machine from the energy source(s). The machine uses the following
energy sources:
- AC power / DC power
This is de-energized by removing the AC connection to the machine.
- Battery.
This is de-energized by disconnecting the battery and protecting the battery
terminal.
5. Lock-out (or tag-out) device application.
Lock out the energy isolating device(s) with:
- an individual lock(s),
- place a warning device on the main switch.
6. Remove residual or stored energy.
Stored or residual energy (such as that in capacitors, air pressure, etc.) must be
dissipated or restrained by methods such as grounding, bleeding down, etc.
7. Verification of isolation.
Make sure that the machine is disconnected from the energy source(s).
First make sure that no persons are in or on the machine. Test to verify the isolation
of the machine. Make certain that the machine will not operate (power cannot be
turned on).
