News Flash: Gasoline and Vapors Are Highly Flammable and Mix with Air

Gasoline vapor, which is heavier than air, also rapidly mixes and spreads with air. Unrestrained vapors of gasoline are quickly flammable.

Many accidents involving gasoline occur when gasoline is used to light bonfires. The gasoline vaporizes quickly after being poured and mixes with the surrounding air. As in the video above, when ignition is attempted, the vapor surrounding the bonfire instantly ignites in a large fireball, engulfing the person holding the ignition source.

Gasoline also floats on water. Gasoline fires are not extinguished well with water.

Respect the vapors. Keep storage containers tight — a good rule because it prevent gas from oxidizing and becoming a gummy nuisance that is bad for engines.
