If a chemical has a high permeation rate, what can be inferred about the PPE's protection?

• A. It provides strong protection
• B. It provides poor protection
• C. It is easy to clean
• D. It is unaffected

Answer: (B)

Permeation rate is the speed at which a chemical moves through protective material. If that rate is high, the chemical passes through the PPE quickly, so it reaches the inner surface and potentially the skin in a short time. That short breakthrough time means the barrier isn’t doing a good job at protecting you, even while you’re wearing it. So the PPE provides poor protection when the chemical has a high permeation rate.
