Some fiberglass safety helmets have anti-static properties, which are achieved by adding anti-static agents to the material or using special manufacturing processes. The principle of action of anti-static agents is to reduce the surface resistance of materials, allowing static electricity to quickly leak. In the production process of fiberglass safety helmets, anti-static agents are uniformly added to the resin or a layer of anti-static coating is applied to the surface of the helmet shell.

When the fiberglass safety helmet belt has static electricity, due to the effect of anti-static agents, the surface charge of the material can be quickly conducted to the ground, thereby avoiding the accumulation of static electricity. This anti-static performance is crucial for use in some special working environments, such as the petrochemical, electronics, and other industries. In the petrochemical industry, static electricity may cause explosions of flammable and explosive gases; In the electronics industry, static electricity may damage precision electronic components.

Glass steel safety helmets with anti-static properties undergo strict anti-static performance testing before leaving the factory. The testing method usually measures the resistance value of the surface of the safety helmet, requiring its resistance value to be within a specified range (generally 1 × 10 ⁶ -1 × 10 ⁹ Ω) to ensure its anti-static effect. However, it should be noted that not all fiberglass safety helmets have anti-static function. When purchasing, products with anti-static labels should be selected according to the actual working environment requirements to ensure work safety.
