The process by which a chemical enters a protective suit through openings in the garment is called?

• A. Degradation
• B. Breakthrough Time
• C. Permeation
• D. Penetration

Answer: (D)

Penetration is the process where a chemical gets into a protective suit by slipping through openings, seams, closures, or any gaps in the garment. This bypasses the barrier at the level of the garment’s integrity, allowing contaminants to reach the wearer without having to move through the fabric itself. Permeation, on the other hand, is the chemical moving through the material of the suit at the molecular level, which may eventually reach the inner surface but stays within the barrier material. Breakthrough time refers to how long it takes for permeation to reach a defined level at the inner surface, not entry through openings. Degradation describes the chemical causing breakdown or weakening of the material itself. Since the question specifies entry through openings, the correct term is penetration.
