According to OSHA 29 CFR 1910.147, which term describes the placement of a lockout device on an energy-isolating device to ensure the equipment cannot be energized?
Answer: Lockout
Lockout is the placement of a lockout device on an energy-isolating device so the machine or equipment cannot be energized until the lockout device is removed.
Before performing lockout/tagout, an authorized employee must first notify which group of people?
Answer: All affected employees
OSHA requires that all affected employees be notified before applying lockout or tagout devices to equipment.
Which step in the LOTO sequence involves verifying that the equipment has been successfully de-energized after isolation?
Answer: Verification
Verification is the step where the authorized employee tests the equipment to confirm it is de-energized before beginning work.
When multiple workers are servicing the same piece of equipment, which LOTO method must be used?
Answer: Group lockout using a hasp with individual locks from each worker
Group lockout requires a hasp that allows each authorized worker to apply their own personal lock, ensuring no single person can re-energize until all workers remove their locks.
Under OSHA's Control of Hazardous Energy standard, how often must LOTO procedures be reviewed?
Answer: Annually
OSHA 29 CFR 1910.147 requires that energy control procedures be reviewed at least annually to ensure they are being implemented properly.
What is the correct order of the first three steps in a lockout/tagout procedure?
Answer: Notify → Shut down → Isolate
The correct LOTO sequence begins with notifying affected employees, then shutting down the equipment, then isolating energy sources.
A tagout device differs from a lockout device primarily because a tagout device:
Answer: Only provides a warning and does not physically prevent energization
A tagout device is a warning tag attached to an energy-isolating device to indicate it must not be operated, but it does not physically prevent re-energization like a lock does.
