Environmental factors that should be considered in the selection of chemical protective clothing

Due to the complex chemical hazard environment, in order to meet the needs of different situations, there are many types of chemical protective clothing, and there are many types of products on the market. The correct choice of chemical protective clothing needs to be selected according to actual needs. The following is an introduction to the environment that should be considered when choosing chemical protective clothing Factors, provide certain guidance and help for the selection of chemical protective clothing.

When there are chemical hazards in the environment, but the type and degree of the hazardous substances are unknown, the built-in heavy-duty chemical protective clothing with the highest protection capacity should be used; for highly toxic poisons and high concentrations of poisons, heavy-duty chemical protective clothing should be considered; For situations where the hazard is relatively high but the operating space is relatively small, consider using external heavy-duty chemical protective clothing; for occasions where flame and toxic hazards exist at the same time, consider using fire-resistant chemical protective clothing; if in addition to chemical hazards, the surrounding environment If there are risks of friction, puncture, cutting, etc., you should consider using heavy-duty chemical protective clothing with wear-resistant, puncture-resistant, and cutting-resistant functions; for high-risk chemical hazards that also exist at the same time, you should consider using fire-resistant chemical protective clothing; due to the combination of a single chemical Compared with chemical protective clothing materials, it is more difficult to protect the mixture. The penetration of one chemical will cause the penetration of another chemical. When the pollutant is a mixture, the choice of chemical protective clothing should be more cautious.

In addition, special attention should be paid: the protective ability of the main material of chemical protective clothing against chemical substances is only one of the key elements of the overall protective efficiency. The structural characteristics of chemical protective clothing and its supporting protective equipment (including respiratory protective equipment, chemical protective gloves, chemical protective The compatibility of boots, etc. are all key factors that constitute the protective ability of chemical protective clothing.
