Lock-out Tag-out electrical equipment ensures proper shut down of electrical systems such as circuit breakers, push-buttons, switches, plugs, and many more. This is to prevent any electrical accidents from industrial high voltage or low voltage applications.
A basic procedure starts by identifying all potential electrical sources for the equipment, some may be a single switch, while some may include capacitors or backup batteries that may need to be disconnected to ensure that the equipment does not receive any electrical power.
Before the technician/maintenance personnel shuts down the equipment, he/she must be informed about the type and magnitude of the work. The personnel must be aware of the hazards surrounding him.
