WebThe terms flammability limit (FL) and explosion limit (EL) have often the same meaning. In Europe the term “explosion limit” is frequently used as in the ATEX directives and in EN 13237:2012 [6]. In the US literature and in international standardization the wording “flammability limit” or “flammable limit” is more common. WebAs we mentioned above, flammability is the main risk when working with hydrocarbon refrigerants. While hydrocarbons are not necessarily toxic like Ammonia it can still have detrimental effects if the concentration is high enough. In … 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 florida panthers free tickets
