Explosion-proof equipment is the best option for those working in hazardous areas, but do you know how this equipment works? Let’s examine this issue in this article.
When researching the concept of explosion protection, you often come across the term Exproof. A common question is which is the best safety strategy to implement in hazardous areas. For example, climbers have different plans for their climbs: different routes where they have the same goal, but depending on the route, one will be better. It would be wise to make an assessment before knowing which path to choose.
Definition of 'Explosion Proof' (Ex-proof)
The EX seal identifies explosion-proof equipment and is a safety strategy adopted for hazardous areas. It is one of the leading security strategies, but its operation still arouses curiosity.
What defines the equipment as Ex-proof is the enclosure that is explosion proof and can prevent damage in your hazardous location. An explosion can create pressure inside the equipment enclosure. This pressure can disperse more sparks and cause an even worse accident. To ensure equipment is Ex-proof, it must be certified according to appropriate safety regulations such as NEC, NFPA, UL and others.
How does explosion-proof equipment work?
This type of equipment is designed to withstand explosions caused by gas or steam. So if the engine produces a spark inside the equipment, its casing will be strong enough not to allow the explosion to disperse into the outside atmosphere. So let’s understand how this design works to provide this level of security.
When an internal explosion occurs in equipment, the pressurized gas looks for a way out of the enclosure. Being aware of this, the design of Ex-proof equipment allows the gas to cool before it goes outside.
Its reinforced casing helps distribute the gas internally, cooling it and preventing pressure from escaping. World safety standards approve this method. However, if the quality of the material used for the case is not good, this precaution is not sufficient. Minor external damage can jeopardize product certification and cause accidents. See below for some examples of how the enclosure works.
