I am Electrical Engineer presently working on Hazardous Area Classification as a part of the project where I am working also.
Electrical Engineer - P.Eng. is person to define Hazardous Area - NOT Chemical.
TABLE showing less / more flammable gases and vapours is very important for that kind of work. Flammable gases and vapours are caovered by API,NEC and other Standards, but some gases are not there .

1. Ignition Temperature.
2. presence(always, sometimes, etc) of these gases / vapors in atmosphere.
There are two classifications, one is Class/Div/Group
and other probably european in class/zones.
