EXPLOSIVE ATMOSPHERE<\/strong>
A mixture of flammable substances in the form of gases, vapors, dusts, fibers, or flyings with air under atmospheric conditions, which, after ignition, allows the propagation of a flame throughout the unburned mixture.<\/p>\n

HAZARDOUS AREA<\/strong>
An area in which an explosive gas atmosphere is expected or may be expected to be present in such quantities that special precautions are required in the construction, installation, and use of equipment.<\/p>\n

NON-HAZARDOUS AREA<\/strong>
An area not located within or around any flammable material.<\/p>\n

NEGLIGIBLE AREA<\/strong>
An area where an explosive gas atmosphere is not present in sufficient quantities to require special precautions in the construction, installation, and use of equipment, or where the risk of explosion (e.g., flash fire) is considered negligible.<\/p>\n

EXPLOSION<\/strong>
Explosion is essentially a special form of combustion. It is the destructive effect that occurs when the pressure created by rapidly expanding gases, resulting from extremely fast combustion, exceeds the strength of the confined space in which they are contained.<\/p>\n
