What is meant by "degradation" in the context of protective clothing?

The term "degradation" in the context of protective clothing refers to the breakdown or deterioration of the material when it is exposed to environmental factors such as chemicals, heat, moisture, or other hazardous substances. This process can compromise the integrity and protective capabilities of the clothing, making it less effective in safeguarding the wearer against hazards. Understanding degradation is crucial for ensuring that the protective gear remains reliable and functional in hazardous environments, as well as for determining when to replace or maintain that equipment to ensure continued safety.

In contrast, other options focus on positive changes to the clothing material or its attributes, which do not apply to the concept of degradation. Hence, the correct understanding of degradation emphasizes the potential risks associated with exposure to harmful elements and underscores the importance of monitoring the condition of protective clothing.
