Level A protection is required when the greatest potential for exposure exists and the greatest level of skin, respiratory, and eye protection is needed. Which description matches Level A?

• A. Is required when the greatest potential for exposure exists, including a positive pressure SCBA and a totally encapsulated suit
• B. Requires only basic eye protection
• C. Uses only gloves
• D. Requires no respiratory protection.

Answer: (A)

Level A is the highest level of protection, used when there is the greatest potential for exposure and you need maximum protection for skin, eyes, and respiratory system. The description that matches Level A describes wearing a totally encapsulated suit with a positive-pressure supplied-air respirator, which provides full-body protection and ensures clean air inside the suit to prevent inhalation of hazardous vapors or gases. This combination is what you use when hazards could contact skin and be inhaled, and you need the strongest containment.

The other options don’t meet that level of protection: basic eye protection leaves skin and inhalation hazards unaddressed, gloves-only protects just the hands, and no respiratory protection fails to guard the lungs against airborne hazards.
