Explosion Proof LED

Class I lights are designed to protect against the ignition of flammable materials or substances. They are used in areas where there may be flammable gases or liquids present. This is the broadest sense in which explosion proof lights are distinguished from each other. The classes are each broken down further into two separate divisions.

• Class I, Division 1 – Where ignitable concentrations of flammable gases, vapors or liquids are present continuously or frequently within the atmosphere under normal operation conditions.
• Class I, Division 2 – Where ignitable concentrations of flammable gases, vapors, or liquids are present within the atmosphere under abnormal operating conditions.
• Class II, Division 1 – Where ignitable concentrations of combustible dusts are present within the atmosphere under normal operation conditions.
• Class II, Division 2 – Where ignitable concentrations of combustible dust are present within the atmosphere under abnormal operating conditions.
• Class III, Division 1 – Where easily ignitable fibers or materials producing combustible flyings are present within the atmosphere under normal operation conditions.
• Class III, Division 2 – Where easily ignitable fibers or materials producing combustible flyings are present within the atmosphere under abnormal operating conditions.

The explosion proof lighting system is designed to protect the people and equipment in a dangerous work environment. However, it is important to understand that the explosion proof lighting system was not designed for just any hazardous work environment. In fact, there are no “one size fits all” solutions when it comes to this type of lighting. The classification system used by the National Electrical Manufacturers Association (NEMA) differentiates between different types of hazardous environments and requires specific types of protection for each.
