Which of the following are signs of CPC failure?

• A. Ripping, glowing surfaces, uneven seams
• B. Discoloration, stiffness, cracking, or sticky surfaces
• C. Loud noises, dull training responses, flame exposure
• D. Color fading, excessive rain exposure, dry rot

Answer: (B)

The signs of Chemical Protective Clothing (CPC) failure include discoloration, stiffness, cracking, or sticky surfaces. These characteristics suggest that the integrity of the material has been compromised due to exposure to hazardous substances, environmental conditions, or aging.

Discoloration indicates changes in the fabric that may affect its protective qualities, while stiffness and cracking suggest that the material is losing its flexibility, which is crucial for movement and proper fit. A sticky surface can imply that the outer layer has broken down due to chemical exposure or degradation, making it less effective in providing protection against hazards. Recognizing these signs is essential for ensuring safety during hazardous material operations, as it allows responders to replace compromised CPC before engaging in potentially dangerous environments.
