THE EXPLOSION-PROOF LIGHT - EXPLAINED

Understanding precisely what constitutes a "explosion-proof" light is the topic of a significant number of the inquiries that we receive on a consistent basis. Customers frequently conflate this language with other designations that they have heard in the past, or they have not been adequately informed regarding the purpose of the light in many cases. Let's make an effort to sort out some of the confusion here.

To begin, let's discuss the usage in its most common form. The Canadian Electrical Code and various other codes and regulations across the world all designate a "Hazardous Location," which is where explosion-proof lights are meant to be used. These lights are designed to be safe for use in these environments. In the context of this discussion, a hazardous location is generally understood to be a place that contains elevated concentrations of flammable compounds in the air that are capable of causing an explosion or a fire. This could be in the form of a gas (such as natural gas, ethanol, or toluene), a dust (such as grain, wheat, or coal), or even a fibre. employees are required by law to utilise equipment that has been specifically designed to limit the danger of igniting flammable materials when these hazards are present. This is done so that catastrophic fires or explosions are not caused by the employees. See this article for a brief introduction to the topic, which includes more background information on the categorization of hazardous areas.

A portable light is a useful piece of equipment that is frequently put to use in these sorts of environments. Imagine that you have been given the task of going into a big tank that was formerly used to store petrol in order to empty it, clean it and check it for any damage. Even after all of the liquid gasoline has been drained from this tank, it is still going to contain combustible gases; as a result, you will need to take precautions to safeguard yourself. However, the inside of the tank is pitch black, so you will need to bring a light with you in order to see what you are doing and complete the task. You will need to bring a light with you that is capable of lowering and minimising the risk of igniting the gases (or dusts, depending on the location), as this is a hazardous location. Explosion-proof and intrinsically safe variations of this lamp are the two primary configurations that are available.

All electrical equipment that needs to be approved for use in hazardous situations must either be explosion-proof or intrinsically safe in order to receive that certification. A similar objective is being pursued, namely to lessen the likelihood of the flammable materials catching fire. However, a different strategy is being utilised. The difference between explosion-proof lights and intrinsically safe lights is that the former are built to be able to resist an igniting of the combustible substance that occurs within the light itself, while the latter are designed to not carry enough current to generate a spark that may ignite the flammable material. For a light to be considered explosion-proof, it must be constructed from a sturdy material that does not spark, have a very thick glass globe that covers the bulb, and have a number of other characteristics that work together to ensure that a worker and the environment around them are kept safe in the event that an ignition occurs within the light. We won't get into the specifics here, but the fact that this was even possible thanks to mechanical engineering is a great accomplishment. Just like it ought to be! We are dealing with the subject of putting people's lives at jeopardy. In order to receive their certification, lights that are inherently safe will often be powered by batteries and have such a low voltage travelling through the circuit that it is physically impossible for a spark to arc through the air. Consider a torch that is powered by a battery but has a design that is specifically tailored for it. As you can see, the terms "explosion-proof" and "intrinsically safe" refer to a similar goal, but their applications are completely different from one another.

It is important that we pause here for a moment to emphasise that all items that are used in hazardous areas MUST HAVE THEIR USE CERTIFIED BY AN APPROVED CERTIFICATION BODY (for example, in Canada and the United States: UL, CSA, ETL, etc.) for the specific kind of hazardous region that they are being used in. This is a very important point that should not be overlooked. You will need to have knowledge of the Class, Division, and Group (or Zone, as it becomes more common) that applies to the place, and you will need to utilise a device that has been explicitly approved for those criteria. Do not, for instance, make the mistake of putting a light that is approved for Class I, Division II into an area that is actually Class I, Division I. In a similar vein, you must not use a light that is rated for Zone 1 in an area that is Zone 0. More on this will be discussed in a subsequent post.

It is important to clear up a few myths regarding explosion-proof lights, which may be found rather frequently online. For instance, a lot of people think that an explosion-proof light prevents any gases or vapours from entering into touch with live electrical power by sealing off any openings through which they could enter. This keeps them from coming into contact with the power even if the light breaks. That is NOT the case in most situations. It is not necessary for explosion-proof lights to be "air tight" in order for them to fulfil their purpose. A significant number of explosion-proof lamps permit gases to enter the light itself. It is essential that they be built in such a way as to avoid any explosions that may be created by those gases from causing injury to the worker or from further igniting gases that may be present in the working environment. Therefore, before to immersing your explosion-proof light in water in order to clean it, it is important to verify with the manufacturer to determine whether or not this method is allowed. For instance, some of the lights that we sell are designed to withstand being power-washed, while others do not effectively seal out water or vapour.

On the other hand, several non-explosion-proof lights that are "vapour-proof" in their construction are available for purchase today. It is essential to avoid making the assumption that these lights are similarly explosion-proof because the majority of them are not. A lamp that is explosion-proof is required to have a certification stating that it is explosion-proof, and this certification should be shown conspicuously in any sales materials as well as on the product itself. Keep in mind that not every light that can withstand explosions can also withstand vapour, and similarly, not every light that can withstand explosions can withstand vapour. Ask questions to ensure that you are acquiring the appropriate instrument for the task at hand.

This is a brief explanation of how the terms "explosion-proof" and "intrinsically safe" are utilised in relation to portable lighting devices. Please do not hesitate to get in touch with us if you have any inquiries or require any further explanation.
