Hazardous area light fittings are designed to withstand specific conditions, such as very hot temperatures, in areas classified as hazardous. How to choose the right hazardous light fittingsHazardous areas, also known as potentially explosive areas, are defined by numbered ‘zones’. They are spaces in which there is a risk of fire or explosion due to the presence of flammable or combustible substances. Hazardous light fittings are built to cope in the different zones. As well as choosing the right light for your zone, other factors to consider include temperature classification, lamp type and voltage. Hazardous light fittings are also designed with different safety features included like flame proof, anti-corrosion or emergency.How do hazardous area light fittings work?Hazardous light fittings can switch on and off automatically. Most fittings come with the lamps included, but others can be fitted with a lighting ballast, for example. Many hazardous light fittings can be adjusted from a narrow to a wide beam, and are made with a polycarbonate diffuser to resist harsh environments.
