Class I: A hazardous location in which flammable gases or vapors may be present in the air in sufficient quantities to be explosive or ignitable, such as petroleum refineries, aircraft hangars, dry cleaning plants, utility gas plants or storage areas for liquified petroleum or natural gas, and spray finishing areas.
Division 2: Abnormal condition, where ignitable concentrations of flammable gases, vapors or liquids are not like to exist under normal operating conditions, for example:Closed storage drums containing flammable liquids in an inside storage room would not normal allow the hazardous vapors to escape into the atmosphere. But if one of the containers is leaking, you've got an abnormal condition.
Group A - The only substance in group A is acetylene because it is a gas with extremely high explosion pressures.
Group B - This group includes hydrogen and other materials with similar characteristics.
Group C & D - The most usual Class 1 groups. They comprise the greatest percentage of all Class I hazardous locations. Found in Group C is ethylene. Found in Group D are many of the most common flammable substances such as butane, gasoline, natural gas and propane.

Class II: Combustible dust may be present
Division 1: Ignitable concentrations of hazards exist under normal operation conditions and/or where the hazard is caused by frequent maintenance or repair work or frequent equipment failure
E: Combustible metal dusts: aluminum, commercial alloys and magnesium
F: Combustible carbonaceous dusts: carbon black, charcoal, coal and coke dusts
G: Other combustible dusts: Chemicals, flour, grain, plastic and wood

Class II: Combustible dust may be present
Division 2: Ignitable concentrations of hazards exist under abnormal operation conditions
F: Combustible carbonaceous dusts: carbon black, charcoal, coal and coke dusts
G: Other combustible dusts: Chemicals, flour, grain, plastic and wood

Class III: Easily ignitable fibers or flyings may be present
