Five factors should be considered for the correct selection of chemical protective clothing.
 
One is the manufacturing material of chemical protective clothing. At present, there is no chemical protective clothing that can block all types of toxic chemicals. Improper selection can cause the rapid aging of protective clothing fabrics or the rapid penetration of poisons, which can harm the wearer.
 
The second is the structure of chemical protective clothing. For toxic and harmful substances such as gas, steam, aerosol and dust, chemical protective clothing with airtightness or airtightness should be selected. For the protection of non-volatile liquids and solids, it is generally unnecessary to consider the airtightness or airtightness of clothing.
 
The third is environmental factors. When there is chemical hazard in the environment, but the type of chemical substance and the degree of hazard are unknown, the built-in heavy chemical protective clothing with high protection capacity should be used; for high-toxic poisons or high-concentration poisons, heavy chemical protective clothing should be used; the degree of hazard is higher , But the working space is relatively narrow, you can consider using external heavy chemical protective clothing; in the presence of flame and poison hazards at the same time, you should use fire-resistant chemical protective clothing; in addition to poison hazards, there are friction, thorn, cut and other hazards, should Use heavy-duty chemical resistant clothing that is wear-resistant, cut-resistant, and stab-resistant. Care must be taken when choosing chemical protective clothing when there are multiple poisons or hazardous factors.
 
Fourth is the job status. When the operating environment temperature is high and the operating intensity is large, you should consider using breathable chemical protective clothing, or chemical protective clothing with self-cooling function, or optional refrigeration clothing.
 
Five is the human factor. The main consideration is whether the clothing fits and whether the operator is in good physical and mental state. Especially for people who wear fully enclosed heavy chemical protective clothing, they have higher requirements for physical and psychological conditions.
