A hazardous area is defined as an area in which a flammable or explosive gas and air mixture is, or may normally be expected to be, present in quantities such as to require special precautions for the construction and use of electrical equipment and machinery. Ex equipment carries a marking plate that includes details about the surroundings and external influences the equipment has been certified for. Can you interpret the codes?
