To ensure compliance under 1910.147, hazardous energy sources, such as electrical, pneumatic, hydraulic, chemical and thermal energy, need to be properly isolated to a zero-energy state through a ...

It is a common practice to lockout and/or tagout control devices. In a nuclear power plant’s control room with its many analog controls, you might (for example) see red covers over specific switches.

Residual current circuit breakers (RCCB) play a narrow but important role in electrical protection. They are frequently specified, often misunderstood, and regularly credited with capabilities they ...

A circuit breaker that trips repeatedly is often assumed to be defective, but that assumption is frequently wrong. Breakers respond to conditions downstream, and replacing one without understanding ...

To ensure compliance under 1910.147, hazardous energy sources, such as electrical, pneumatic, hydraulic, chemical and thermal energy, need to be properly isolated to a zero-energy state through a ...

In its simplest (and perhaps least effective) form, lockout/tagout (LOTO) consists of three steps: Identify the breaker (or fuse) that supplies power to your equipment. Open the breaker. Hang your ...
