Which locations require explosion-proof electrical testing?

Why do I need an explosion proof test?

一、It’s safety and security.

In places where there are flammable and explosive gases, dust and other hazardous substances, such as petrochemical, coal mine underground, grain storage and other environments, the operation of electrical equipment may produce electric sparks, arcs or high temperatures, with the risk of triggering an explosion. Through testing can ensure the normal operation of explosion-proof electrical equipment, reduce the possibility of explosion accidents, to protect the lives of personnel and corporate property safety.

• It’s a regulatory requirement.

Many industry-related laws, regulations and standards mandate regular testing of explosion-proof electrical equipment, for example, in hazardous chemical production and storage enterprises must comply with national regulations on the installation, use and testing of explosion-proof equipment, or face penalties.

三、It is equipment performance maintenance.

Detection can be timely found explosion-proof electrical equipment damage, aging and other issues, such as damage to the explosion-proof surface, aging seals, etc., to ensure that the explosion-proof performance of the equipment is in a good state, to extend the service life of the equipment and reduce maintenance costs.

What locations require explosion-proof testing?

I. Petroleum and chemical industry sites:

Refineries: In the process of distillation and cracking of crude oil, a large amount of flammable and explosive gases, such as propane and butane, are produced, and any electric spark may cause an explosion.

Chemical plants: the production of a variety of chemicals, such as the production of methanol, ethanol workshop, its environment is full of combustible vapors, explosion-proof electrical equipment requires strict.

II. Coal and other mining sites

Underground coal mines: there are flammable gases such as gas (the main component of which is methane), and coal dust can also explode under certain conditions, so mining, transportation and other equipment need to be explosion-proof.

Metal mines: underground mining sites, such as gold and aluminum mines, may generate combustible gases, especially during the mining of some sulfide ores, which need to be protected from explosions.

III. Dusty industrial sites

Grain storage and processing places: in the transportation of grain, grinding and other links will produce a large amount of flour dust, flour dust reaches a certain concentration will explode when it meets an ignition source, so grain warehouses, flour mills and other places of electrical equipment to explosion-proof.

Wood Processing Workshop: Sawdust generated during wood processing belongs to combustible dust, which has the danger of explosion after reaching a certain concentration in the air.

IV. Gas production and storage sites

Natural gas refueling stations: During the refueling process, there is a high risk of natural gas leakage, and the surrounding environment is prone to the formation of combustible gas buildup.

LPG Storage and Distribution Stations: Areas where LPG is stored and loaded and unloaded, where large quantities of combustible gases are present, and where explosion-proof testing of electrical equipment must be carried out.

Do schools and shopping malls need to be blast tested?

Generally speaking, ordinary schools and shopping malls do not require explosion-proof electrical testing. However, if there are places involving chemical experiments in schools, such as chemical laboratories, because some flammable and explosive chemical reagents, such as alcohol, hydrogen, etc., will be used and stored, this environment requires explosion-proof electrical testing. In shopping malls, if there is a gas boiler room or an area where a large amount of flammable gas is used (e.g., natural gas piping in the catering area, etc.), in order to prevent explosions caused by the leakage of flammable gases, explosion-proof testing of the electrical equipment in the area is also required.
