Explosive atmospheres occur when flammable gases, mist, vapors or dust are mixed with air. This creates a risk of explosion. The amount of a substance needed to create an explosive atmosphere depends on the substance in question. The area where this possibility exists is defined as a potentially explosive atmosphere.

These atmospheres can be found throughout industries, from chemical, pharmaceutical, food, to power, and wood processing. The areas may also be known as “hazardous areas” or “hazardous locations.”
