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

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

Answer: (A)

Penetration is the process by which a chemical enters a protective suit through openings in the garment. When there are gaps such as torn fabric, seams, cuffs, or a zipper that isn’t sealed, a contaminant can bypass the barrier and reach the wearer. Permeation would be the chemical moving through the barrier material itself, not through openings. Diffusion is one mechanism by which permeation can occur, describing how molecules move within the material, while adsorption means the chemical sticks to a surface rather than passing through. So openings in the suit create a direct path for the contaminant, which is why this is penetration.
