In personal protection levels A through D, what does Level A indicate?

• A. The most protective level
• B. The least protective level
• C. Requires only gloves
• D. Moderate protection

Answer: (A)

PPE levels describe how much protection is provided in hazardous environments. Level A is the highest level of protection because it uses a fully encapsulated chemical–protective suit together with a self-contained breathing apparatus, giving complete skin, eye, and respiratory protection against unknown or highly toxic vapors, gases, and potential immersion. This level is chosen when the hazard is unknown or presents extreme risk, so the wearer needs maximum protection. The other levels provide less protection: Level B removes the encapsulated suit and relies on splash protection with a SCBA, Level C uses an air-purifying respirator with less skin protection, and Level D is just basic, minimal protection. So the best description of Level A is that it is the most protective level.
