Lock out, tag out is not required to do which task?

• A. Collect vibrations data from a shaft bearing
• B. Open the electrical cabinet
• C. Replace a fuse in live panel
• D. Install a new motor under power

Answer: (A)

Lockout/tagout protects workers by isolating energy sources during maintenance or servicing so equipment cannot start or release stored energy unexpectedly. Collecting vibrations data from a shaft bearing is a monitoring task that doesn’t involve servicing the equipment or altering its energy state; you’re not performing work on the electrical or mechanical systems that could cause a hazardous energy release, so LOTO isn’t required for that activity. Opening an electrical cabinet, replacing a fuse in a live panel, or installing a new motor while everything is powered all involve exposed electrical hazards or the risk of unexpected energization, and they require isolating and securing the energy sources to protect workers.
