WebThe Flammable Range (also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced.. Three basic requirements must be met for explosion to take place: flammable substance - fuel; oxidizer - oxygen or air; source of ignition - spark or high heat WebFlammability is determined by the flash point of a material. Flash point is the minimum temperature at which a liquid forms a vapor above its surface in sufficient concentration that it can be ignited. Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier. What affects flammability?
