Use of cell phones and other electronic devices during the refueling process is...

• A. Prohibited
• B. Permitted in designated areas
• C. Permitted if hands-free
• D. Only during breaks

Answer: (A)

During refueling, electronic devices must not be used because the operation involves flammable vapors and ignition sources must be eliminated. A cell phone can contribute sparks or static buildup and it can distract personnel from monitoring hoses, gauges, and grounding; that distraction can lead to mistakes that create spills or fires. Using a phone, even hands-free, still diverts attention from critical safety steps. Some rules set aside areas for quiet use, but during fueling the safest, most consistent practice is to prohibit device use entirely. If communication is needed, step away from the fueling area and use standard signals or a supervisor to relay information, and always follow site-specific procedures.
