Content: Each of these areas can also be broken down into either division one or two locations. A Division 1 location is a location where the hazard is normally present. A Division 2 location is a location where the hazard is present but normally contained. An accident would have to occur to make the area extremely hazardous. For example, the area inside of a spray paint booth is a Class I, Division 1 location. It is a Class I location because flammable gases and vapors will be coming out of the paint gun. It is a Division 1 location because in normal operating conditions the hazard is present. You don’t want to strike a match inside of a paint booth while someone is painting.
