The physical destruction or decomposition of chemical protective clothing (CPC) by a chemical action is called:

• A. Erosion
• B. Degradation
• C. Deterioration
• D. Corrosion

Answer: (B)

Degradation is the term that fits chemical action breaking down protective clothing. When a chemical interacts with the fabric and chemically alters or breaks down the material, its structure and barrier properties can be compromised, leading to swelling, cracking, embrittlement, or loss of resistance. This is different from erosion, which is physical wear from mechanical action; deterioration is a general decline not specific to chemical attack; and corrosion is chemical attack primarily associated with metals. In polymer CPC, exposure to solvents, oxidizers, or other reactive agents can cause degradation by breaking polymer chains or altering the material, reducing its protective performance.
