In 1910.333(b)(2), what is required while an employee is exposed to fixed electric equipment or circuits?

The requirement specified in 1910.333(b)(2) emphasizes the necessity of locking out or tagging out parts of fixed electric equipment or circuits when employees are exposed to these risks. This is a critical safety measure designed to prevent accidental energization or start-up of the equipment, which could lead to serious injuries or fatalities due to electric shock or burns.

Lockout/tagout procedures ensure that equipment is properly shut off and not able to be started up again until maintenance or service work is completed. By implementing these practices, employers provide a controlled environment where employees can safely handle or work on electrical components without the risk of live wires or circuits coming into play unexpectedly. This practice is part of a broader safety standard aimed at protecting workers in environments where electrical hazards are present.
