Personal protection for workers exposed to toxic substances

Personal protection of workers exposed to poisons has special significance. Poisons invade the human body's portals. In addition to the respiratory tract, they can be infiltrated through the mouth and skin. Protective equipment belonging to the workplace includes protective clothing, dust masks and gas masks.

According to the nature of toxic substances, the characteristics of toxic operations and protection requirements, accident cabinets, first aid kits and personal protective equipment (antivirus clothing, gloves, shoes, glasses, filter-type gas masks, long-pipe masks) shall be provided in the toxic working environment. Air respirators, oxygen masks, etc.) The service radius of human health devices such as human irrigators and eyewashers should be less than 15m.

(1) Protective clothing. Including protective clothing, shoes, caps, glasses, gloves and so on. In order to prevent poisons from invading the human body or damaging the human body through the skin, the selection and design of protective clothing should be conducive to anti-virus, light weight, durability and without affecting body temperature regulation.
