After repairs on fuel burning equipment, what must the licensed operator do with the equipment?

The requirement for the licensed operator to check the repairs and be present during startup is critical for ensuring the safety and proper functioning of fuel burning equipment. After any repairs, it is essential to verify that all work was completed correctly and meets the necessary safety standards. Being present during the startup allows the operator to monitor the equipment for any irregularities or issues that may arise as it begins operation, which helps prevent accidents or malfunctions. This step not only protects the equipment but also safeguards the premises and individuals nearby.

The other options do not provide adequate measures for ensuring the safety and efficiency of the equipment post-repair. Simply signing off on the repairs and leaving without overseeing the startup does not ensure that the equipment is operating correctly. Notifying the fire department may be necessary in some circumstances, but it is not a standard procedure following repairs. Similarly, reapplying for the operation permit is unnecessary unless there have been significant changes to the system or if the permit has expired, rather than a routine repair. Therefore, thorough oversight at startup is a fundamental responsibility of the licensed operator after any repair work on fuel burning equipment.
