In hazardous locations, extreme care should be exercised in designing facilities to prevent fires and explosions. These are credible threats when the place is filled with flammable and combustible materials. Engineers should be mindful of the lighting equipment so as to ensure that potential harm is virtually eliminated. Certified hazloc lighting products should be used in such projects.
The identification of a hazardous location is critical at the outset. Studying the ignition triangle to determine the probability of fire is one of the first things that safety officers must do. The three things necessary for fire are fuel to burn, air to provide oxygen, and heat to start the combustion.
There are two classes of hazardous locations. Class I have flammable gasses or vapors that are confined in closed containers. Class II have combustible dusts that have accumulated to a level that is enough to interfere with electrical equipment.
