The terms Explosion Proof and Hazardous Location are not the same. These area designations mandate different approaches.

Explosion Proof Designated AreasEXC-explosion-proof-light-fixture

Explosion Proof Lights are typically Class I, Division 1 rated. They must prevent high voltage and amperage components from becoming an ignition source. A heavy enclosure surrounds the spark producing components. If vapors or gas leak in and ignite, the mechanism impedes hot gases from passing through. Yet, allows the flow of cold gases through joints.

Hazardous Location Designated Areas

In North America, hazardous locations are a combination of classes, divisions and zones.

Class & Divisions System (Canada & US Only):

Class I, Division 1 - Where ignitable concentrations of flammable gases, vapours or liquids can exist all of the time or some of the time under normal operating conditions. 

Class I, Division 2 - Where ignitable concentrations of flammable gases, vapours or liquids are not likely to exist under normal operating conditions.

Class I Groups - A- Acetylene, B - Hydrogen, C - Ethylene, D - Propane

Class II, Division 1 - Where ignitable concentrations of combustible dusts can exist all of the time or some of the time under normal operating conditions.

Class II, Division 2 - Where ignitable concentrations of combustible dusts are not likely to exist under normal operating conditions.

Class II Groups - E - Metal Dust, F- Coal Dust, G - Grain Dust

Class III, Division 1 - Where ignitable concentrations of ignitable fibres and flyings can exist all of the time or some of the time under normal operating conditions.

Class III, Division 2 - Where ignitable concentrations of ignitable fibres and flyings are not likely to exist under normal operating conditions.

 

Zones Systems (IECEx/ATEX/Canada & US)nemalux-hazardous-location-lighting

Hazardous areas are classified into Zones based upon the frequency of the occurrence and duration of an explosive gas/dust atmosphere, as follows:

Zone 0, 20 - A potentially flammable atmosphere is present continuously or for long periods or frequently.

Zone 1, 21 - A potentially flammable atmosphere is likely to occur in normal operation occasionally.

Zone 2, 22 - A potentially flammable atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

Explosion Proof LED Lights for Hazardous Location Installation and Use

Nemalux-explosion-proof-lighting-products-1Explosion proof lights on site reduce the risk of ignitable dust and gases. Nemalux fixtures provide quality illumination and offer peace of mind for workspaces. Our systems use solid-state LED light sources for safety, reliability, and longevity.

Luminaire selection starts with area designation corresponding to hazardous location certification. Existing facilities conducting lighting upgrades could match the rating of older light fixtures. Additional explosion proof area information is at the bottom of this page.

Advantages of Utilizing Explosion Proof LED Lights in Hazardous Locations

Proper lighting at an industrial workplace is paramount for safety and optimized workflow. It supports efficient performance, accuracy, and task completion by ensuring optimal visibility. Also, it maintains a focus on human-centric lighting strategies. It enhances environmental awareness while creating a more comfortable atmosphere, which reduces stress. Conventional lights pose risks in hazardous locations due to their design and construction.

Explosion Proof LED lights undergo stringent certification processes to ensure suitability. All components and materials must meet specific requirements outlined in the electrical code. Their superior construction and quality control make them safe for particular locations.

LED options not only pose fewer hazards but allow smaller yet robust enclosures. These features allow for designs with high protection against external elements.

When specifying explosion proof lights for hazardous location use, please consult with Nemalux. Our current catalog is a great starting point.

Information on Hazardous/Explosion Proof Fixtures

Hazardous location design and explosion-proof light fixtures are for challenging environments. These rated lights have exceptional durability and visual results. Nemalux provides superior illumination in extreme workplaces. Flammable gases, vapors, or dust define a hazardous location. Lighting equipment installed in such areas must undergo specialized design and testing. These LED lights prevent explosions caused by potential arcing or high surface temperatures.

NEMALUX-XR-Series-explosion-proof-lighting-products-1It's important to reiterate that explosion-proof is not the same as hazardous location. Detailed explanations for area designations are available from UL, CSA, and other NRTLs.
