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.

What is lighting explosion proof?
Explosion-proof lighting is a category of lighting that protects against uncontained sparks. The internal electrical reactions of a light fixture are not affected by fumes or hazardous materials.
What is meant by explosion proof?
The National Electrical Code states that explosion proof means an apparatus that is capable of withstanding a gas or vapor explosion. If there is an explosion, it will be contained within an enclosure.
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.
What is difference between EXE and EXD?
Exd enclosures are considered to be ‘flame proof’ which means that they should contain an explosion.
Does explosion proof need lighting?
OSHA requires certified explosion proof lights to be used for hazardous locations, such as areas with flammable vapors, liquids or gases. These types of environments help classify what class and division a light is certified for.
What is an explosion proof light?
Intrinsic safe lights are designed to not carry enough current to cause a spark that could ignite the flammable material, while explosion-proof lights are designed to resist an ignition of the flammable material inside the light itself.
Does flame proof mean it will not light?
A light fixture that is rated to be explosion proof doesn’t mean it’s built to survive an explosion. It simply means that it is designed to prevent the device from exploding.
What is the difference between flameproof and explosion proof?
The word fireproof is usually used in Asian countries. There is an American word for blast proof. The EU uses EExd. The only difference is the term.
What is explosion proof classification?
There are new class requirements for NEC. Class I, II and III enclosures can be explosion-proof if they contain an explosion sufficiently to prevent the explosion of the atmosphere around them.
How does an explosion proof enclosure work?
When there is an explosion, gases escape through any of the paths or openings in the enclosure. As escaping gases exit through openings that are long in proportion to the width of the enclosure, they will be sufficiently cooled. The escaping gas needs to be cooled down.
What makes an enclosure explosion proof?
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.
Why explosion proof enclosures are critical for business?
In case of an accident, explosion proof enclosures help to make sure that all the people working in that environment are safe. If you work in an industrial setting, you may be exposed to conditions that can quickly escalate, leaving you with very short reaction time.
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 will be clearly indicated by the nameplate if the motor is certified by an agency.
Are all LED lights explosion proof?
What makes a light explosion proof?
To be certified, explosion-proof lights must be made of durable, non-sparking material, a very thick glass globe over the bulb, and other features to ensure that the worker and the surrounding environment remain safe.
Can LED lights caught on fire?
Even though they are hot, 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 break easily?
An alternative to incandescent light bulbs is the use of LEDs. Their technology is completely different, and as a result they last a long time. The same goes for light bulbs and LEDs, they break due to heat exposure.
Are LEDs intrinsically safe?
Intrinsically safe lighting is usually low-powered and has batteries. Low-voltage bulbs are used in the lighting. This is the way in which high-intensity discharge lights are classified.
