Our LED linear industrial explosion proof lighting fixtures (rated Class I, Division 1) are designed specifically for highly hazardous areas where an explosion may occur due to the constant presents of airborne explosive materials.

A few common applications for an explosion proof fixture include:

• paint booths
• petroleum refineries
• gasoline storage
• spray finishing
• fuel servicing

A Class I, Division 1 location is an environment in which:

• Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors can exist under normal operating conditions
• Ignitable concentrations of such flammable gases, flammable liquid-produced vapors, or combustible liquids above their flash points may exist frequently because of repair or maintenance operations or because of leakage
• Breakdown or faulty operation of equipment or processes might release ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors and might also cause simultaneous failure of electrical equipment in such a way as to directly cause the electrical equipment to become a source of ignition.

 

Class I locations consist of areas where gases, vapors, or liquids may exist that have the potential to become flammable or ignitable. There are two different divisions that exist in Class I, they are Division 1 and Division 2. There are also three Zones; Zone 0, 1 & 2.

DIVISIONS:

• Division 1 is a subset of Class I and is classified as an area where the explosive or flammable gases, vapors, or liquids mentioned above can exist under normal, everyday operating conditions.
• Division 2 is also a subset of Class I and is classified as an area where the explosive or flammable gases, vapors, or liquids mentioned above are not likely to exist during regular operation.

ZONES:

• Zone 0 is described as the presence of explosive or flammable gases, vapors, or liquids for long periods of time during operating conditions or during a large portion of the operating conditions.
• Zone 1 is described as the presence of explosive or flammable gases, vapors, or liquids for some of the time during normal operating conditions.
• Zone 2 is described as there not being a likelihood of explosive or flammable gases, vapors, or liquids present during normal operating conditions.
