Science popularization the structure and selection of protective clothing

Medical protective clothing refers to protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning personnel, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, people entering infected areas, etc.). Its function is to isolate bacteria, harmful ultrafine dust, acid and alkaline solution, electromagnetic radiation, and so on, to ensure the safety of personnel and keep the environment clean.

 

Composition of protective clothing

 

The protective clothing is composed of jacket, trousers, hat, etc., and is designed into the appropriate size and shape. The design size and shape as well as the combination method are subject to the effective prevention of harmful invasion. It can be a one-body structure or a split structure. The structure of protective clothing should be reasonable, easy to wear and take off, and closely combined.

 

Choice of protective clothing

 

In the process of chemical leakage and on-site disposal of poisoning, the function of protective clothing is to provide barrier protection for the site staff to contact with the site harmful chemicals and harmful gases, dust, smoke, fog and so on in the air. According to the type of poison source and environmental conditions, the on-site chemical accident will be divided into hot zone, warm zone and cold zone. The protection needed in each area is different, and the protective clothing used in one area cannot be used in other areas.

 

The choice of protective clothing should be based on the type of leakage, the way of existence, environmental conditions and concentration of comprehensive consideration. For the presence of corrosive gaseous substances (steam, dust, smoke, etc.) in the site, the protective clothing should have corrosion resistance, high isolation efficiency, a certain degree of water resistance, clothes and trousers, cuffs, trouser legs have good tightness, etc.; For non-evaporative solid or liquid chemicals, only protective clothing with a certain isolation efficiency is required. The selection of protective clothing can refer to the technical parameters and application range in the product manual.
