Said that the acid-base personal protection, according to the division of the body parts, can generally be divided into respiratory protection and skin and eye protection in two parts.
First, the protection of the respiratory tract Respiratory protection is mainly to prevent respiratory inhalation acid mist, acid vapor acid gas and alkaline dust, can be selected as follows protective equipment.
1 acid gas protective equipment. Acid masks and gas masks can be selected according to the nature and concentration of the acid gas. In areas where the acid mist is too high and the acid-alkali liquid splashes at the same time, use an acid-proof mask or an acid-proof mask.
2 alkali dust protection products. Different dust masks can be used depending on the nature and concentration of alkaline dust.
Second, the protection of the skin, eyes, skin, eye protection is mainly to block away, reduce the skin direct contact with acid and alkali liquids, acid mist, acid gases and alkaline dust and other harmful substances, to avoid acid-base droplets, acid mist, alkaline dust Harmful to the eyes. According to the production conditions and the nature of work, different protective equipment can be selected.
1 anti acid and alkali liquid products. Contact with acid-base liquids. The necessary protective articles generally use acid and alkali resistant rubber products (including latex products), polyethylene plastic film products and artificial leather products, non-penetrable silk and acid-proof silk, etc.; its varieties are anti-acid and alkali rubber overalls, bib pants, aprons, Sleeves, gloves, boots, shoes, etc.

Although the standard has been set aside and the replacement standard has not yet been promulgated, the verification of the special labor protection article safety sign certificate, the issuance of the industrial product license, and the laboratory accreditation of the inspection organization still use this standard as the technical basis. Therefore, the production of acid proof workwear is currently under way. The standard is still used for operations, inspections, administrative licenses, etc.
2 acid-proof steam supplies. During the operation of contact with acid mist and acid vapor, pure woolen and chemical products that are resistant to acid vapor corrosion are used, such as woolen clothes and polyester work clothes.
3 anti-alkaline dust supplies. A generally denser cotton fabric can be used.
