After fueling, what should you do before starting the engine?

• A. Start the engine immediately
• B. Snuff the engine space before starting and wait if you smell gas
• C. Ventilate only after starting
• D. Ignore fuel smells

Answer: (B)

Fuels vapors can ignite, so the important practice is to clear and ventilate the engine space before any start after fueling. If you smell gas, snuff any ignition sources in the engine space, ventilate the area, and wait for the vapors to disperse before attempting to start the engine. This is safer than starting immediately, which could ignite vapors, and it’s essential rather than ignoring the fuel smell.
