What factors will cause the protective performance of chemical protective clothing to decline

Chemical protective clothing, whether it is a limited-time use chemical protective clothing or a reusable chemical protective clothing, has a service life. We can only maintain and maintain the chemical protective clothing in advance if we understand in advance which factors will cause the protective performance of the chemical protective clothing to decline. Extend the service life of chemical protective clothing and ensure the personal safety of users.

What factors will cause the protective performance of chemical protective clothing to decline

Any physical damage to the suit, such as cracks in the fabric, seams (such as missing stitches or loss of sealing tape), integrity of the flap system, or any signs of wear and tear (such as abrasion, flexing, pressure/strain, Deterioration due to UV radiation); contamination, cleaning and decontamination; repairs; poor storage or past shelf life can all cause unpredictable aging and reduce the protective properties of chemical protective clothing.

Contamination, cleaning and decontamination

Instructions for use of chemical protective clothing contain instructions for cleaning and disinfection or decontamination, which should be distinguished from decontamination. Hygienic cleaning is done to avoid the spread of disease, to eliminate unpleasant odors, and to ensure that no cleaning supplies are left behind. Decontamination is to remove dirt, chemical contamination or biological contamination. Whether chemical protective clothing must be discarded or can be reused after decontamination is determined by the intended use as specified by the chemical protective clothing manufacturer.

Also, for chemical resistant suits made of water repellent materials, information should be available on whether re-water repellency is required.

During the decontamination process of Class A chemical protective clothing or Class B chemical protective clothing, chemical pollutants on the surface of chemical protective clothing are removed or chemical pollutants are neutralized. Proper decontamination allows re-use of chemical protective suits marked as reusable. Decontamination can be done using a variety of processes, such as physical means (pressurized water, washing), chemicals (inactivating contaminants) or a combination, but should always be done according to the suit manufacturer's instructions.

Decontamination should be checked for signs of deterioration by the appearance of the suit (change in weight, swelling, stiffness, discoloration, delamination, holes/cracks/tears) and odor.

Repair and Repair

For reusable chemical protective clothing, especially fully enclosed chemical protective clothing. If repairing does not ensure that the suit is in good working order, dispose of the suit. Make sure the suit has been sanitized before patching and that all patching is done.

storage

Storage arrangements must be made to avoid damage to chemical protective clothing from sunlight, dust, moisture (too much or too little moisture) or extreme temperatures. Mechanical damage during transport or storage, or in the same room as chemicals should be avoided. User instructions should also provide information on shelf life (eg storage and use time of non-destructive chemical protective clothing). The above is the answer provided by Huatong Xiaobian about which factors will cause the protective performance of chemical protective clothing to decline. I hope it will help you understand chemical protective clothing! Determine that the chemical protective suit is no longer in use, and should be discarded in accordance with local laws and regulations, considering that chemical contamination will occur.
