When people hear the term explosion proof lights they think about many things. The phrase is confused very often and few entrepreneurs know exactly what is the function of these lights. Even more important, a business owner should know if they need these lights for their factory.
Defining The Hazardous Locations
Explosion proof lights are used in hazardous locations, as they are defined by the electrical code or other regulations across different states. The general meaning of a hazardous location is a place where there are high amounts of inflammable substances, which can easily cause an explosion. The substances can be under any form: gas, dust or fibers. In factories where such substances are being processed the workers need to wear protective gear and the area needs to be equipped with special devices which can signal a potential danger and reduce the risk of explosion.
How to Use Hazardous Location Lights
Even if you work in a place filled with toluene or coal you still need light. But a traditional lighting fixture can become a danger, as it can ignite the flammable substances. The explosion proof lights reduce the risk of fire and enable the workers to do their job under normal circumstances.
For example, if the worker has to inspect a tank which is used to store flammable substances, they will need to have a light source with them. A traditional light can be dangerous, so they will need a portable explosion proof light.
Types Of Hazardous Locations Lights
Hazardous locations lights come in two main types: explosion-proof and intrinsically safe. While they both reduce the risk of fire, the way they do this is different. Intrinsically safe lights are made to carry small amounts of electrical power, to avoid causing a spark and igniting the flammable materials. Most intrinsically safe lights are powered by small batteries and have a very low voltage, which prevents the apparition of a spark. Explosion-proof lights are made from strong materials which can keep the potential flame away from the worker and prevent a fire, if a fire ignites inside the light. All the materials used in the production of these lights are durable and very thick, to prevent a catastrophe.
Common Misconceptions About Explosion Proof Lights
Many people assume that explosion proof lights are completely air tight, preventing the gas or vapors from entering the light itself. This is not true; the lights do allow the substances to enter in them, but they prevent them from exploding and harming those around. At the same time, if a fire appears inside the light, it will not be able to exit and come into contact with other materials. Before you invest in explosion proof lights you need to know exactly what type of lighting fixture your workers need. Check their certification and make sure it fits your needs, otherwise the light might become a danger for your workers. If you are not sure about the product, just ask the vendor, who can guide you towards the best lighting fixture for your company.
