Safety Procedures Flashcards

Under OSHA 29 CFR 1910.147, who is permitted to remove a lockout device from an energy-isolating device?

Answer: The employee who applied it

Each lockout device must be removed by the employee who applied it, except under the standard's specific documented alternative procedure.

After applying locks and tags to a pump motor, what is the next required step before beginning work?

Answer: Verify zero energy by attempting to start the equipment

Verification of isolation (try-out) confirms that the equipment cannot be energized before work begins.

What is the main limitation of using a tag alone, without a lock, on an energy-isolating device?

Answer: Tags are warning devices and do not physically prevent operation

Tags provide a warning only and offer no physical restraint, so tagout-only programs require additional safety measures.

When a shift change occurs during a lockout, how should continuity of protection be maintained?

Answer: Oncoming workers apply their locks before outgoing workers remove theirs

Orderly transfer requires the oncoming lock to be in place before the outgoing lock comes off so protection is never interrupted.

Which type of stored energy must be released or restrained during lockout of a hydronic heating system?

Answer: Residual water pressure and heat in the piping

Stored hydraulic pressure and thermal energy in hot-water piping can cause burns or injury and must be relieved.

A group lockout on a large air handler typically uses which device so multiple workers can each attach a personal lock?

Answer: A lockout hasp

A multi-hole hasp lets each worker apply a personal lock so the device cannot be operated until all locks are removed.

How often must an employer conduct a periodic inspection of its energy control procedures under OSHA?

Answer: At least annually

OSHA requires a periodic inspection of energy control procedures at least once a year.
