Which action is described as reducing the fire risk during refueling?

• A. Drive back to your home terminal immediately if you notice a fuel leak after having taken a rest break
• B. Touch the fuel hose nozzle against the filler pipe before filling up with fuel
• C. Leave your engine running while refueling
• D. Gently 'drag' the brakes when the vehicle is in motion

Answer: (B)

When refueling, static electricity can build up and create a spark that could ignite fuel vapors. The best safety step is to discharge that static by grounding yourself, which is done by touching the fuel hose nozzle to a metal part of the vehicle such as the filler pipe. This provides a conductive path to the vehicle and the ground, so any static charge is released before fuel flows. So touching the nozzle to the filler pipe is the proper precaution to reduce fire risk during fueling. The other actions don’t address grounding or, in fact, can introduce ignition sources—leaving the engine running during refueling can supply a heat source or spark, while actions unrelated to fueling safety don’t help reduce fire risk.
