Wrenches (Explosion-Proof)
A wrench (explosion-proof) is a work tool which has an explosion-proof function that prevents sparks even when subjected to friction or shock. It is suitable for work in the chemical industry, gas industry, flour mills, cleanrooms, etc., because it is convenient to use in work sites where there is a high risk of ignition and explosion. The main material for the wrench (explosion-proof) is copper, which does not generate sparks even when scraped, but since copper is soft and is not suitable for tools, a small amount of beryllium or cobalt is added and has about the same strength as general work tools. However, the copper used in the material of the wrench (explosion-proof) reacts with acetylene gas, so it is strictly prohibited to use it in places where acetylene gas is used. There are adjustable wrenches, hex keys, ratchet wrenches, combination wrenches and so on, and you need to choose one according to your application and purpose.
