Which of the following duties can be performed by Certificate of Fitness Holders?

The ability of Certificate of Fitness Holders to perform duties related to fire alarm systems is governed by specific regulations and standards. Holders of a Certificate of Fitness are typically permitted to carry out visual inspections of smoke detectors. This includes checking for physical damage, ensuring that devices are clean and free from obstructions, and confirming that the detectors are in their appropriate locations and properly installed.

Visual inspection is an essential component of fire safety since it helps to identify issues that could compromise the operational readiness of smoke detectors, which are vital for alerting occupants in the event of a fire. This responsibility is critical in maintaining a safe environment and ensuring that the fire alarm system functions as intended.

In contrast, performing maintenance tasks such as detailed repairs, component replacements, or programming of fire alarm systems often require more specialized training and certification beyond the basic Certificate of Fitness. Such tasks involve in-depth knowledge of the fire alarm system's technical specifications and operational guidelines.
