Can fueling of aircraft occur in hangars?

Fueling aircraft typically should not occur in hangars due to several safety and regulatory concerns. Hangars are primarily designed for the storage and maintenance of aircraft, where potential fire hazards are of significant concern. The presence of fuel, which is highly flammable, increases the risk of fire and explosion in an enclosed space.

A key aspect of aviation safety regulations is that fueling operations are usually required to take place in open areas where there is adequate ventilation and a clear opportunity to manage any potential fuel spills or leaks. Hazards such as static electricity, improper ventilation, and the concentration of flammable vapors make hangars unsuitable for fueling. Instead, designated fueling areas are built specifically to handle the risks associated with the activity. Therefore, the assertion that fueling can occur in hangars is not aligned with the safety protocols in place at most airports.
