Static grounding during fueling operations is implemented to prevent static electricity from reaching what hazard?

• A. Sparking hazard
• B. Ground hazard
• C. Electrical fault hazard
• D. Thermal hazard

Answer: (A)

Static grounding during fueling is used to prevent static electricity from causing a spark that could ignite flammable vapors. Fuel systems can generate static charge as liquids move and friction occurs in hoses and fittings. Providing a direct, low-resistance path to earth lets those charges dissipate continuously instead of building up and discharging as a spark at the nozzle or connection. That spark is the ignition source you’re protecting against in fueling operations. Ground hazards pertain to electrical shocks or faults in electrical equipment, which are not the immediate risk addressed by static grounding in this context. Electrical fault hazards involve failures in wiring or devices, and thermal hazards relate to excess heat—not the ignition risk from a static spark in a fueling scenario.
