Hazardous Locations”, “Hazardous Areas” “Explosive Atmospheres”, these terms describe areas where flammable liquids, vapors, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion.


For example, Refinery factory, Oil and gasoline loading docks, Gas stations, Painting manufacture workshop, Pumping stations, Metal Smelting Plant, Mining, Ocean platform, Aerospace, Chemical plant, Vessels, Military, Flour Mill, Distilleries, Power station, Other high humidity, high temperature, dusty locations. As the automation industry of today continues to expand, we will see an increased use of explosion proof equipment

 

There are basically two requirements for components to be considered explosion proof for Class I Division 1 atmospheres. First, the industrial lighting fixture must be able to withstand an internal explosion if it should occur and secondly, it must work to prevent the spread of the internal explosion to the surrounding saturated atmosphere. This is typically accomplished by joints and closures built into the actual lighting fixture. The lighting fixtures themselves may be damaged, but they are designed so as not to allow the explosion or other possible sources of ignition to reach the hazardous atmosphere.
