WebThe four hydrocarbons that are gases at room temperature (methane, ethane, propane, and butane) are all flammable. Many times, they are also stored under pressure and can explode if heated.... 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
