Where should a smoke detector maintenance log book be kept in the absence of a fire safety director?

The correct choice for where a smoke detector maintenance log book should be kept in the absence of a fire safety director is in the building engineer's office. The building engineer is typically responsible for the maintenance and operation of the building systems, including fire safety equipment. Keeping the maintenance log in the engineer's office ensures that the log is accessible to personnel who are trained to manage and respond to issues related to safety systems, including smoke detectors.

This location allows for efficient oversight of the equipment's status and maintenance history, facilitating prompt action if any issues arise. The accessibility of the log to the building engineer supports adherence to safety protocols and compliance with regulations, ensuring that maintenance is regularly performed and documented.

In contrast, while properties may have other secure locations or designated offices, these options may not provide the same level of immediate access by qualified personnel compared to the building engineer's office.
