The process by which a chemical enters a protective suit through openings in the garment BEST describes:

• A. Penetration
• B. Permeation
• C. Absorption
• D. Adsorption

Answer: (A)

This question tests how a chemical can get into protective clothing. The term for a chemical entering through openings in the garment—such as seams, closures, or gaps—is penetration. It means the barrier is breached at a point in the garment, allowing the chemical to pass through the openings rather than diffusing through the fabric itself.

Permeation, by contrast, is the chemical moving through the material on a molecular level without a hole or opening. Absorption is the liquid being taken up into the fibers of the material, and adsorption is molecules sticking to the surface of the garment. Since the scenario specifies entry through openings in the suit, penetration is the best description. To reduce risk, maintain garment integrity, ensure proper closures, and avoid damage that creates gaps.
