Step-by-step explanation:
The correct answer is option 4) Steps taken to ensure the safety of the building during the drill. While it is critical to record the date and time the system was taken off-line, the reason for taking the system off-line, and the name of the person responsible for that action, the log book does not typically require a detailed list of safety steps taken during the drill. This is because the log is meant to document the operational status of the fire alarm system rather than the procedures of the drill itself. Drill procedure details are often documented elsewhere in drill reports or emergency planning documents.
When taking the fire alarm system off-line during a drill, it is important to include the date and time the system was taken off-line, the reason for taking the system off-line, and the name of the person responsible for taking the system off-line in the log book.
These details help in documentation and accountability. Including the steps taken to ensure the safety of the building during the drill is also important, as this information ensures that appropriate measures were taken to safeguard individuals and property during the drill.
