All You Needed To Know about Explosion proof Lighting:

by Astin Smith Article Writer

Lighting techniques in hazardous locations has always been an area of concern.  A hazardous area can be broadly classified as a topology, in which the concentration of inflammable gasses, vapors or dust can be well over the threshold of the permissible index. Some common examples of such areas are coal mines, chemical plants and refineries etc. It is at these areas do the most basic electrical requirement i.e. lighting needs to be specifically designed and manufactured. Here lies the concept of explosion proof lighting.

·         Why do you need explosion proof lighting?

 

Arc discharge or high surface temperature of the electrical gadgets leads to dangerous situations when it comes to volatile and hazardous conditions. A simple example of it is that, a simple light switch emitting a spark is of no concern in a usual environment. But when it comes to a location filled with highly inflammable gasses, this might set of a chain of tumultuous reactions.  Lighting, again, being a very basic necessity in all forms of industrial endeavors, explosion proof lighting methods are a must have.

·         History of explosion proof lighting.

 

Ø  From the time of proposing the introduction of electric lighting into coal mines, the various dangers associated with the idea was widely known. Apart from the flammable gasses and the high dust content in the mine air, the presence of considerable methane was a huge deterrent.

Ø  It was not before the initial part of the 1900’s that the first mine gas protected lighting techniques were used.

Ø  Hence onward, with the advent of technology, this particular area of lighting went from strength to strength.

 

 

·         Types of explosion proof lighting.

 

These types of lighting materials are made to meet stringent conditions and specifications. Most of them contain a protective casing that helps to keep the dust and other harmful elements at bay. In a broader sense, the lights are classified as follows:

I)                    Class 1 lights: These lights are UL rated for specifically confined spaces. This type of lights is lights are specifically used for painting booths, cleaning vessel or fuel cells.

II)                  Class 2 lights: Areas that contains grains or munitions especially require these types of lights.

The usual types of explosion proof lighting is as follows:

a)      Fluorescent lights:

b)      HID lights.

c)       Incandescent lights.

d)      Induction lights.

e)      Photo controls.

f)       Portable lighting.

g)      Visual signal lighting.

h)      Flameproof lighting.

·         Common characteristics of most explosion proof lighting.

 

Ø  Protective casing that is almost inherent in all forms of explosion proof lights.

Ø  Minimum amount of environmental emission.

Ø  A good heat dissipation technique.

Ø  Most of the lights are water proof, duct proof and impact resistant.

Ø  In most cases internal rectifiers are present.

 

 

Explosion proof lighting is not only a precautionary measure but also a basic necessity and a mandatory regulation, which every form of industry must abide by.
