The signs of safety signs for special labor protection articles consist of the safety signs of special labor protection articles. The signs of labor safety are accepted and issued by the Safety Sign Management Center of Special Labor Protection Products of the China Academy of Safety Production Sciences.
Enterprises that produce anti-static overalls must obtain special safety protection products. The production and business entities must not purchase and use anti-static uniforms without LA safety signs; the purchased anti-static overalls must be inspected by the safety production technical department or management personnel of the unit. .
