OSHA requires certified explosion proof lights for hazardous locations, such as areas with flammable vapors, liquids or gases. These types of environments help classify what class and division an explosion proof light is certified for.

What is an explosion proof light?
Intrinsic safe lights do not carry enough current to cause a spark that could ignite the flammable material, whereas explosion-proof lights do.
What is meant by explosion proof lighting?
An explosion-proof lighting category is designed to protect against uncontained sparks. The internal electrical reactions of a light fixture are not affected by fumes or hazardous materials.
How does explosion proof lighting work?
The sparks from the lighting fixture can potentially ignite the gases in the atmosphere. An explosion proof lighting fixture is usually encased in a thick frame made of steel or aluminum.
Does Class 1 Div 2 require explosion proof?
Class I locations must be explosion-proof, Class II locations must be dust-proof, and Division 1 motor must be dust-proof. The motor’s enclosure is designed to exclude hazardous materials.
Is Class I Div 2 explosion proof?
A Class I Division 2 light is not held to the same standard as a Division 1 product. There is no requirement for a light to contain an explosion to meet the requirements for Division 2. They can’t cause an explosion in environments that they’re approved to be used in.
Is LED lighting explosion proof?
Are LED lights intrinsically safe?
Intrinsically safe lighting usually includes batteries and rechargeable batteries. Low-voltage bulbs are used in the lighting. This is the way in which high-intensity discharge lights are classified.
Can LED lights caught on fire?
Even though they are hot to touch, led strip lights are not likely to catch fire. Incandescent bulbs emit excessive heat, the light sources can ignite a fire on overheating, but as the light source produces light at a lower temperature, they don’t catch fire as easily.
Do LED lights get hot enough to start a fire?
The technology of LEDs doesn’t require heat to produce light, so they won’t start a fire. Most of the energy used by HID lights is absorbed by the light that is 800 nanometers in wavelength.
What voltage is considered intrinsically safe?
Intrinsic safety is the method of protection for control and instrumentation circuits if the nominal voltage is less than 24VDC and the current is less than 100mA.
Does flame proof mean it will not light?
It doesn’t mean that light is built to survive an explosion. It simply means that it is designed to prevent the device from exploding.
What is flame proof lighting?
In other words, flameproof equipment stops the fire from starting in the hazardous area. There are many explosion protection techniques used for light fitting, motor, and JBs.
What is flame proof apparatus?
“Flame proof apparatus” means an apparatus that can resist an explosion of the inflammable gas that may occur within it and can prevent the transmission of flame such as will ignite the inflammable gas which may be present in the area”, according to the Director General of Motor Vehicles.
What is the difference between intrinsically safe and explosion proof?
What is the level of safety in the event of an explosion? Intrinsically Safe means that a temperature transmitter is not able to cause an explosion. If there is an explosion, it will be contained within an enclosure.
What is explosion proof rating?
To meet the criteria for the explosion proof rating, an enclosure must be able to contain any explosion from within its housing and prevent sparks from within its housing from starting a fire.
How does an explosion proof enclosure work?
Gases can escape through any of the paths or openings in the enclosure. Explosion-proof enclosures are designed so that escaping gases will be sufficiently cooled when they exit through openings that are long in proportion to the width of the enclosure. The escaping gas needs to be cooled down.
Why explosion proof enclosures are critical for business?
In case of an accident, explosion proof enclosures help to make sure that the people working in that environment are safe. If you work in an industrial setting, you might be exposed to conditions that can quickly escalate, leaving you with very little time to react.
What is an explosion proof box?
junction boxes made of explosionproof and flameproof are used in hazardous areas. The boxes are designed to contain an explosion from gases, vapors, dusts and fibers.
How do I know if my motor is explosion proof?
An explosion proof motor is marked with a name that identifies it as suitable for a hazardous environment. The hazardous location Class, Division, and Group for which the motor is suited will be indicated by the nameplate.
How do I know if my electric motor is explosion proof?
A listing identification plate is affixed to the motor enclosure to show that the motor has been certified for explosion proof. The class, division, and group are all defined by the plate.
