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 explosive proof lighting?
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 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.
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 the same 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.
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.
How does an explosion proof enclosure work?
Gases can 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.
Does explosion proof need lighting?
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 a light is certified for.
What is the difference between flameproof and explosion proof?
The word fireproof is usually used in Asian countries. A word that means explosion proof is an American one. Everyone in the EU uses EExd. There is no difference between the two.
Is explosion proof intrinsically safe?
What is the risk of an explosion? Intrinsically Safe means that a temperature transmitter is not able to cause an explosion. If an explosion occurs, it will be contained in an enclosure.
Are all LED lights explosion proof?
Can LED lights caught on fire?
There is no chance of led strip lights catching 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. A lot of this lighting uses low-voltage bulbs. This is the way in which high-intensity discharge lights are classified.
Can LED lights be left on 24 7?
Well-manufacturedLED lights can be left on for 7 days a week and can be left on for 24 hours a day. Unlike conventional types of light, LEDs don’t produce a lot of heat, which makes them less likely to catch fire.
