What is the rule regarding cell phones and electronic devices during refueling operations?

• A. They may be used in designated areas
• B. They are allowed if on silent mode
• C. They are prohibited during refueling and in areas with petroleum vapor
• D. They can be used if hands-free

Answer: (C)

Preventing ignition sources during fueling is the priority. Petroleum vapors are highly flammable, and electronic devices can introduce ignition risks through sparks, battery faults, or even RF emissions. Using a cell phone or other electronic device during refueling or in areas where fuel vapors may be present adds a real danger and can distract from essential fueling procedures. That’s why the rule is that cell phones and electronic devices are prohibited during refueling and in areas with petroleum vapor. Keeping devices away from these zones eliminates the potential ignition source and helps ensure safe operations; turning devices on silent or using hands-free does not remove the risk near vapors.
