Question

1910.147, which step must always be completed before maintenance work begins? a. notify affected employees, isolate energy sources, and apply lock/tag devices b. remove all locks and tags

Explanation:

For OSHA standard 1910.147 (Lockout/Tagout), before maintenance, the proper lockout - tagout procedures start with notifying affected employees, isolating energy sources, and applying lock/tag devices. Removing locks/tags is done after maintenance, not before. So option A describes the correct pre - maintenance steps.

Answer:

A. Notify affected employees, isolate energy sources, and apply lock/tag devices
