Flammable Vapour (Vapor) is a vapor from flammable products such as gasoline, kerosene, paint thinner, and solvents that is above its lower flammable limit (LFL) concentration. The Flammable Vapours are often heavier than air and may travel along the ground and collect in low or confined areas, and any source of ignition in these areas could cause an explosion or a fire. A zone of flammable vapor will exist in equilibrium with a flammable or combustible liquid any time it is above its flash point.
