gate in the presence of an ignition source
The maximum vapor to air concentration
Upper Explosive Limit(UEL)
above which a flame will not propagate
The temperature at which a liquid will
Flash Point give off sufficient vapors that will ignite
readily given an ignition source
Ratio of the weight of a liquid or solid as
Specific Gravity
compared to an equal amount of water
A materials ability to stay within the area
Persistence
