Which ignition-risk control set is required during fueling near aircraft?

• A. Bonding and grounding, no smoking, spark control, engine off during fueling.
• B. No smoking only.
• C. Engine off during fueling only.
• D. Bonding and grounding, no smoking, spark control, engine off during fueling, and use of a fire watch.

Answer: (D)

Ignition risk during fueling near aircraft comes from flammable fuel vapors and static electricity, so the safest approach is a complete set of controls. Bonding and grounding the fueling equipment and aircraft prevents static buildup and discharge that could ignite vapors. No smoking removes a primary ignition source in the area. Spark control reduces the chance of any sparks around the fueling operation. Keeping the engine off during fueling eliminates ignition from engine components and exhaust. A fire watch provides continuous monitoring to detect leaks, vapors, or spills and to stop fueling or summon help if a hazard appears. This combination covers static control, ignition-source control, and active monitoring, which is why it’s the best choice. Other options omit one or more critical elements, leaving gaps in protection.
