What is the permanent log of the authorizations given for all tag-out actions?

• A. Maintenance log
• B. Tag-out log
• C. Risk assessment log
• D. Work order log

Answer: (B)

The key idea is that there is a formal, enduring record specifically dedicated to every energy isolation action. A tag-out log serves as the official book of record for all tag-out authorizations, capturing who authorized each tag-out, when it was applied, the equipment or energy source involved, and when it can be removed. Keeping this as a permanent log ensures there is a clear, auditable trail that the equipment was properly isolated before work began and that re-energization is only done with proper authorization. This focused record-keeping distinguishes tag-out activities from other logs like maintenance, risk assessments, or work orders, which track different activities and information.
