During fueling, what must cabin crew ensure?

• A. Both no smoking and no means of ignition
• B. No smoking
• C. No smoking and no food consumption
• D. No smoking and no use of electrical equipment

Answer: (A)

The main safety idea here is eliminating ignition sources in the fueling area. Fuel vapors are highly flammable, so any spark or heat can ignite them. That’s why the rule requires both no smoking and no means of ignition—that covers not only the absence of flames but also any equipment or activity that could create a spark or heat, including electrical devices. If you only ban smoking, a spark from electrical equipment or other ignition sources could still occur. A rule that mentions no food consumption isn’t relevant to ignition risk, and restricting electrical equipment alone is narrower than needed. So the best answer is the one that combines no smoking with no means of ignition to comprehensively prevent ignition during fueling.
