Class 1 Division 1, or C1D1, is a classification of explosion ratings. It’s designed to work in explosive environments and hazardous conditions where ignitable concentrations of flammable combustible vapors, liquids, or gases are always present.
Class 1 Areas are groups. Groups are categorized by the type of material found. The most common groups are:
Note: all of our class 1 div 1 lighting are certified for Groups C and D. Some are certified for Group B. Please check the specifications for each light if you specifically need C1 D1 Group B.
Yes, C1D1 is explosion-proof under UL844 testing standards.
Yes, it is. Class 1 Division 1, or C1D1, is the strictest of all standards. It’s designed for an environment where danger is always present
The main difference is the presence of gas or other explosive materials. C1D1 handles ‘always present dangers. Division 2 in Class 1 is for ‘sometimes present’ environments.
Like other LED lights, explosion-proof fixtures provide the same key benefits.
They also meet the certification requirements needed in Class 1 Div 1 applications. And they will provide a safe lighting environment and works well in a hazardous location requiring repair or maintenance operations.
These c1d1 lighting fixtures are rated to run for a very long time. Running these lights for 12 hours a day, 365 days a year – you can expect 10+ years of life from them without maintenance, bulb, or ballast changes.
