According to the definition section in the OSHA lockout/tagout standard, an energy isolation device is “a mechanical device that physically prevents the transmission or release of energy. . . “. The OSHA definition goes on to explain that energy isolation devices include, but are not limited to, the following:
- A manually operated electrical circuit breaker;
- A disconnect switch;
- A manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors, and, in addition, no pole can be operated independently;
- A line valve;
- A block; and,
- Any similar device used to block or isolate energy.
