The harm of the electric arc to the human body: The burn of the electric arc explosion is the more serious injury of the electric arc injury. It mainly comes from the heat radiation and splashing molten metal emitted by the arc explosion. Arc explosion will cause continuous burns or dripping of clothing after being ignited, resulting in severe burns. Arc-proof clothing has the functions of flame retardant, heat insulation and antistatic, and will not fail or deteriorate due to washing. Once the arc-proof clothing comes into contact with arc flames or hot heat, the high-strength and low-strength bulletproof fibers inside will automatically expand rapidly, making the fabric thicker and denser, forming a protective barrier to the human body.
