[tips] anti-static overalls equipped with knowledge

Conductive silk fabrics are woven into the latest imported conductive fibers in the world, completely different from the traditional anti-static finishing, and are permanent anti-static fabrics. In order to achieve washing resistance, the conductive wire does not break, and the conductive performance is good and at the same time it reduces the adhesion of the product itself to the dust particles. The fabric uses 100D/48FFDY polyester filament, the distance between the conductive filaments is 0.5cm, and the organization mechanism is 1/2 twill. The density is 172*88, the grammage of the square meter is 120g/m2, the dyeing is environmental protection dyeing, the conductive weaving method is 1/2 twill weave, and the imported conductive filament and polyester filament are processed by water jet and air jet loom , After special processing and finishing, the fabric has the function of anti-static and dust-proof, and it also has the characteristics of washing resistance and wrinkle resistance.

The standard (Appendix D of GB 12014-1998) classifies gas explosion hazard locations according to the frequency, duration, and risk level of explosive substances:

Class 0 zone: Under normal circumstances, explosive gas mixtures occur continuously, frequently for a short time, or exist for long periods of time.

Class 1 area: Under normal circumstances, there are places where explosive gas mixtures may occur.

Level 2 Zones: Under normal circumstances, explosive gas mixtures cannot occur, only occasionally occurring in an unusually short time.

In areas of Class 0 and Class 1 that are dangerous places for gas explosion, and the minimum ignition energy of flammables is less than 0.25mJ, anti-static overalls shall be provided. Typical combustibles with a minimum ignition energy of 0.25 mJ are propane-combustion hydrocarbons, acrylonitrile, diethyl ether, hydrogen, carbon disulfide, furan, benzene, methanol, and the like. In the “Regulations for the Selection of Protective Equipment for Labor Protection” (GB11651-1989), it is required that the operation of flammable and explosive sites of Type A01 must be equipped with anti-static overalls; the operation of Type A02 flammable dust sites can be made of anti-static overalls. The "Standard for the Provision of Labor Protective Equipment (Trial)" (Safety [2000] No. 189 of the State Economic and Trade Commission) also requires gas station operators, liquefied petroleum gas tankers and similar types of work, and must be equipped with anti-static overalls.
