What is the purpose of a lockout-tagout (LOTO) audit and how often should it be performed?

• A. To verify ongoing LOTO compliance; typically conducted annually or after changes to equipment or procedures.
• B. To replace lockout devices every month.
• C. To train new hires on cleaning schedules.
• D. To audit PPE inventory.

Answer: (B)

The main idea behind a lockout-tagout audit is to verify that energy isolation procedures are being followed and that the overall LOTO program remains effective in protecting workers. It looks at how the control of hazardous energy is actually carried out during maintenance or servicing, checks that devices and tags are used correctly, reviews the documentation and training, and identifies gaps or opportunities for improvement so the procedures stay current and safe. The standard practice is to perform this audit at least once a year, and also whenever there are significant changes to equipment, processes, or personnel that could affect how energy is controlled. It’s not about replacing lockout devices monthly, nor about cleaning schedules or PPE inventory.
