LED Lights for Class 2 Division 1 Hazardous Locations

What is LED Class 2 Div 1 Lighting?

Class 2 Division 1 (C2D1) is a stringent hazardous location rating for industrial lighting. With 15+ years of experience in commercial lighting, we have seen these fixtures used where ignitable concentrations of dust, fibers, or flying particles are typically present during normal operations. Unlike Class 1, which addresses gases, vapors, and liquids, Class 2 Division 1 focuses on combustible particulate hazards that pose continuous ignition risks.

OSHA's workplace safety standards stress the importance of proper lighting in hazardous locations to prevent ignition sources. The OSHA electrical safety standards require all electrical equipment in classified locations to be suitable for the specific hazardous conditions, supporting worker safety and compliance.

Where Can I Find a List of Lights That Are Rated for Class 2 Division 1?

Our hazardous location inventory offers several options for C2D1 compliance:

• Browse our LED Class 1 Division 1 lights collection, which includes dual C2D1 ratings.
• Explore our LED Class 1 Division 2 lights with additional C2D1 certification for Groups E, F, and G.

Will Class 1 Division 1 Certified Light Work in a Class 2 Division 1 Environment?

Most of our Class 1 Division 1 fixtures are dual certified for both Class 1 and Class 2 Division 1, specifically for Groups E, F, and G. Always verify the rating label on each fixture, but our C1D1 inventory generally meets C2D1 requirements when properly specified. This dual certification helps avoid maintaining separate inventories for different hazardous classifications.

Will Class 1 Division 2 Lighting Work in a Class 2 Division 1 Environment?

This depends on the fixture model and group classification. Some Class 1 Division 2 fixtures also have C2D1 certification, usually for Groups E, F, and G. Confirm exact rating requirements with your local authority, as mixing Division 1 and Division 2 can create compliance issues.

What are Groups E, F, and G Associated with our Class 2 Division 1 Light?

Group classifications define the types of combustible materials present:

• Group E - For environments with combustible metal dusts like aluminum, magnesium, titanium, and other alloys found in metalworking and manufacturing.
• Group F - For locations handling combustible carbon-based materials such as coal dust, charcoal powder, and carbon black used in industrial processing.
• Group G - For other combustible dusts not in Groups E or F, including wood flour, grain dust, sugar, flour, and plastic powders common in food processing, agriculture, and woodworking.

The National Electrical Code (NEC) provides guidelines for hazardous location classifications and equipment selection. NFPA 70 (NEC) Article 500 sets requirements for electrical installations in hazardous locations, including group classifications for different combustible materials.

How Do I Know if Your Class 2 Division 2 LED Lighting is Certified and Compliant?

All hazardous location fixtures we supply are tested under the UL844 standard for safety in hazardous locations. Each product specification lists the exact Classes, Divisions, and Groups covered by its certification, which is model dependent. We provide complete UL listing information and certification numbers with every shipment, supporting documentation for safety inspections and insurance compliance.

Safety and Performance Certifications

Our fixtures carry key certifications: DLC Premium for energy efficiency and rebate eligibility, UL Listed for electrical safety, and ETL Listed for product safety compliance. DLC Premium certification ensures the highest efficiency standards and maximum rebate eligibility.

The DesignLights Consortium (DLC) sets energy efficiency standards that help facilities maximize savings and rebate opportunities. DLC's Technical Requirements for LED luminaires ensure certified products meet high performance criteria for reliable energy savings and long-term value in industrial lighting.

Warranty and Support

All our lights include at least a 5-year warranty, with USA-based support. Our team is committed to resolving warranty claims quickly to keep your lighting operational.

Expert Specification Support for Hazardous Locations

Our specialists have 15+ years of experience with hazardous location requirements. We offer complimentary custom lighting plans to ensure proper fixture placement and certification alignment for your Class 2 Division 1 environment. Our team provides energy savings projections and detailed photometric analysis to optimize safety compliance and efficiency. This support helps ensure your upgrade meets regulatory requirements and maximizes return on investment.

Common Mistakes and How to Avoid Them

We often see C2D1 specification errors discovered during inspection, leading to costly fixes. Most issues result from not understanding your dust classification before ordering fixtures.

• Not verifying the Group certification needed for your combustible material. Confirm if you need Group E, F, or G before ordering.
• Assuming all explosion proof fixtures are suitable for dust applications. Class 1 gas ratings do not automatically cover Class 2 dust hazards.
• Mixing Division 1 and Division 2 equipment in the same zone. Inspectors will flag this.
• Skipping proper conduit sealing and grounding per NEC Article 502. Dust infiltration through electrical connections can create ignition sources.
• Ignoring temperature ratings for specific dust types. Aluminum dust requires different specs than grain dust.
• Mounting fixtures where dust accumulates on the lens without planning for maintenance access. Regular cleaning is needed to maintain light output.
• Choosing lower IP ratings to save costs. Extra cleaning and maintenance often outweigh initial savings.
• Not considering how your dust collection system affects fixture placement. Dead air zones can cause heavier dust buildup.

LED Lights for Class 2 Division 1 Hazardous Locations Frequently Asked Questions

What is LED Class 2 Div 1 Lighting?

Class 2 Division 1 (C2D1) is a hazardous location rating for environments where ignitable concentrations of dust, fibers, or flying particles are present during normal operations. Unlike Class 1 ratings that address gases, vapors, and liquids, Class 2 Division 1 specifically targets combustible particulate hazards.

Will Class 1 Division 1 Certified Light Work in a Class 2 Division 1 Environment?

Many Class 1 Division 1 rated fixtures carry dual certification for both Class 1 and Class 2 Division 1 applications, specifically covering Groups E, F, and G. Verify the specific rating label on each fixture, as coverage is model dependent.

Will Class 1 Division 2 Lighting Work in a Class 2 Division 1 Environment?

Coverage varies by specific fixture model and group classification. Many Class 1 Division 2 fixtures carry additional C2D1 certification for Groups E, F, and G. Confirm exact rating requirements with your local government authority, as mixing Division 1 and Division 2 requirements can create compliance gaps.

What are Groups E, F, and G Associated with our Class 2 Division 1 Light?

Group E covers combustible metal dusts such as aluminum, magnesium, and titanium. Group F includes carbon-based materials such as coal dust, charcoal powder, and carbon black. Group G covers wood flour, grain dust, sugar, flour, and plastic powders.

How Do I Know if Your Class 2 Division 2 LED Lighting is Certified and Compliant?

Every hazardous location fixture undergoes testing under the UL844 standard. Each product specification identifies the exact Classes, Divisions, and Groups covered, though coverage is model dependent. Complete UL listing information and certification numbers are provided with every fixture shipment.
