How far must you remain from aircraft being serviced with fuel or oxygen?

Maintaining a safe distance from aircraft being serviced with fuel or oxygen is a critical safety procedure. Keeping a distance of 50 feet is essential to minimize the risk of fire or explosion due to potential fuel spills or vapors that can ignite. This distance is established based on the accumulation of safety standards and practices in aviation fueling operations, which recognize that hazards increase as one gets closer to the source of flammable materials.

Other distances provided in the options, such as 25, 75, and 100 feet, do not match the best practices recommended for such operations. While 100 feet may seem prudently safer, it is not the standard minimum distance established for aircraft fuel servicing. The 50-foot guideline ensures a balance between operational efficiency and personnel safety, making it the appropriate distance to ensure that individuals are well outside the immediate risk zones associated with fuel and oxygen servicing.
