Explosion Proof Lights Classifications and Requirements

For purpose of definition, we will explain the Class and Div System of lighting fixtures. For a full explanation on electrical, explosion safe lighting and safety information, a full description is provided on the OSHA website.

 

LED Explosion Proof Lighting

Our LED hazardous location lighting products have been designed and built to be used safety in the presence of dirt, dust, water, hydrogen, acetylene and other flammable petrochemicals. These hazardous area lights are commonly used in industrial applications where ignitable flammable gases are present. Hazardous location LED lights not only run safely in these dangerous environments, but they also reduce energy costs and improve safety through high quality light output.

 

Intrinsically Safe LED Lights

Intrinsically safe lighting fixtures are built to eliminate sparking, which would otherwise potentially ignite in an environment with ignitable fumes in the area. By eliminating sparking,  these intrinsically safe location LED light fixtures will remain safe in the harshest industrial-type areas.  Our commercial hazardous location LED lighting options come in multiple shapes, styles, division ratings, and classifications, allowing you to choose the fixture best for your zone requirement.

Class I Explosion Proof

 

Class I areas are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class I Environments include:

 

  • Petroleum refining and dispensing facilities
  • Ethanol facilities
  • Dip tanks containing flammable or combustible liquids
  • Dry cleaning plants
  • Petrochemical plants
  • Plants manufacturing organic coatings
  • Solvent extraction plants
  • Plants manufacturing or using pyroxyle (nitrocellulose) type and other plastics
  • Locations using inhalation anesthetics
  • Utility gas plants, storage and handling of liquefied petroleum and natural gas
  • Aircraft hangers and fuel servicing areas
Class 1 Division 1
Flammable concentrations of combustible liquids, vapors or gases exist under normal working conditions.

Class 1 Division 2
Flammable concentrations of ignitable vapors, liquids, or gases exist under abnormal working conditions.

Class 1 Areas
Group A (acetylene)
Group B (hydrogen)
Group C (ethylene and propane)
Group D (propane, butane, methane, and benzene)

Class II Explosion Proof

Class II locations are those that are hazardous because of the presence of combustible dust.

These environments include:

 

  • Grain elevators and bulk handling facilities
  • Manufacture and storage of magnesium
  • Manufacture and storage of starch
  • Fireworks manufacture and storage
  • Flour and feed mills
  • Areas for packaging and handling of pulverized sugar and cocoa
  • Some coal preparation plants and coal handling facilities
  • Spice grinding plants
  • Confectionery manufacturing plants

Class 2 Division 1
Combustible concentrations of flammable dusts exist in the atmosphere under normal working conditions. 

Class 2 Division 2
Combustible concentrations of ignitable dust exist in the atmosphere under abnormal working conditions. 

Class 2 Areas
Group E (metal dust)
Group F (charcoal and carbon)
Group G (wood, plastic, starch, and flour)

Class III Explosion Proof

Class III locations are hazardous because of the presence of easily ignitable fibers or flyings but in which such fibers or flyings are not likely to be in suspension in the air in quantities sufficient to produce ignitable mixtures.

These environments include:

 

  • Woodworking plants
  • Textile mills
  • Cotton gins and cottonseed mills
  • Flax producing plants

    Class 3 Division 1
    Combustible fibers or materials that produce ignitable particles exist under normal working conditions.

    Class 3 Division 2
    Combustible fibers or materials that produce flammable particles exist under abnormal working conditions.

    Class 3 Areas
    These are not categorized into groups but comprise of sawdust and cotton

    Explosion Proof Lights Have a Robust Design for Containment

     

    LED Refinery Lighting

    Use Explosion proof lights in these areas

     

    • Chemical processing plants
    • Aircraft maintenance areas
    • Enclosed fueling stations
    • Paint spray booths
    • Offshore oil and gas rigs
    • Chemical storage units
    • Ship tanks
    • Refineries
    • Oil and Gas Storage
    • Grain silos

    The main task of explosion proof lights is to stop an explosion from escaping, whenever one occurs. 

    Explosion Proof lights are designed to contain any explosions that happen inside the light. They are not vapor tight fixtures. They are designed, certified and tested so that any issue inside the light is not transferred to the hazardous environment in which they are installed.

    They should not be confused with intrinsically safe lights. An intrinsically safe light is designed so that it never creates a problem, such as a spark. They tend to be lower power, low voltage lights and are typically battery powered, like a flashlight.

    Why you would choose LED Over Metal Halide

    A Long Lifespan - Which Results In Lowering your Maintenance Costs

     

    LED Explosion Proof Fixtures have many benefits over conventional explosion proof lights. These fixtures have an average life expectancy of 50,000+ hours. Metal halides have an average lifespan between 12,000 and 20,000 hours.

    LED explosion proof fixtures maintain their lumens extremely well. Their lumen maintenance (L70) is typically over 50,000 hours. During the same period, you would have to replaced 2 to 3 HID bulbs. Explosion proof LED lights are more energy efficient than traditional explosion proof lights. Long lifespan of LEDS contributes to lower operating and maintenance costs.

     

    They Emit Less Heat and Lower the Risk of Accidents at your facility

    LEDs are solid-state lighting devices and function reliably because of their heat-saving features. They only produce an average of 3.4 BTUs per hour and are not affected by low temperatures or humidity. This translates to lights that work when workers enter hazardous rooms. Metal Halide require larger fixtures to act as a heat sink to eliminate all the heat generated by the bulbs. While LEDs produce heat, its a fraction of what Metal Halide produces.

     

    They Support Your Eco-Friendly Initiatives

    Since LEDs are more energy-efficient, they reduce the demand on the power grid. And in the process lower greenhouse gas emissions. LEDs convert 95% of the energy they draw into light and only waste 5% as heat. Conventional lights waste 95% of the energy they draw as heat and only convert 5% into light.

    If your company is thinking of implementing eco-friendly initiatives, switch to LED. LEDs do not contain dangerous substances. Their disposal process isn't as costly as that of HID and fluorescent lamps.

    Frequently
    Asked
    Questions

    Are LED lights explosion proof?

    They can be, but not all LED Lights are explosion proof rated. The standard for explosion proof in North America is UL844 standard. Without this certification by a certified testing lab, the light is not an explosion proof rated fixture. Another standard is ATEX, but this rating is an European standard designed for countries in Europe.

    What is explosion proof lighting?

    Explosion proof lights design contains sparks in case of an internal explosion. It prevents the explosion from escaping – hence the term “explosion proof.” The lights lower the risk of a explosive reaction from spreading. The fixtures feature thick casings that cover the luminaires. The thick casing covers all internal components. An explosion proof box house sensors, switches and drivers.

    The design of an explosion proof fixture is very interesting. It forces gas to take longer, complicated routes through different channels and pathways. As it travels, cools down to a safer temperature before release. Explosion proof lights are not airtight. They allow gases to enter their aluminum casings.

    What is the difference between Class 1 Div 1 and Class 1 Div 2?

    Class 1 Div 1 Hazardous Locations are areas that have flammable gases, vapors, and liquids and are present at all times. Class 1 Div 2 Locations are areas that have the same flammible gases, vapors, and liquids but are not present at all times.

    What is the difference between Class 1 and Class 2 Explosion Proof Lights?

    Class 1 Lighting deals with flammable gases, vapors, and liquids. Class 2 Lighting deals with combustible dust particles.
