An isolating device is a mechanical device that physically prevents energy from being transmitted or released. Examples of isolating devices include circuit breakers, valves, switches, and other blocks.
Mechanical, hydraulic, pneumatic, chemical, electrical, thermal, and other energy sources are examples of hazardous energy sources. These energy sources need to be isolated during repairs or maintenance to prevent unexpected re-energization.
