Obtain the safety padlocks, safety tags, safety circuit breaker lockouts, and other equipment needed to complete the work.

Equipment off

Notify all affected employees to stop work and shut down the equipment by normal shutdown procedures. (For example: on/off or start/stop buttons or switches).

Isolation

Operate the circuit breaker lockout to isolate the machine or equipment from the energy source. This usually involves opening an open switch, a circuit breaker, or a closed valve. Note: Do not open an open switch without turning off the device, as it may cause an arc or explosion.

App lock/tag device

Add a safety padlock and tag on each energy isolation device to ensure that it is in a closed state. When the energy isolation device requires a locking device, install a safety circuit breaker lockout, safety padlock, and sign to ensure that it is in the "closed" state.

Power failure: the stored energy is released or suppressed

After using the locking device, all stored or remaining energy must be released, disconnected, restricted, or otherwise made safe.

Verify

Before starting any work, confirm that the machine or equipment is isolated and cannot be activated or restarted by the following actions: manually operate the control button or switch to start or operate the machine or equipment, and return control to their off or neutral position.
