Which PPE level is fully encapsulated with a SCBA?

• A. Level C
• B. Level A
• C. Level D
• D. Level B

Answer: (B)

Fully encapsulated PPE means the wearer is sealed inside a gas-tight suit and breathes from a self-contained air source, so no outside air or contaminants can reach skin or lungs. The best choice describes this combination: a fully encapsulating suit paired with a self-contained breathing apparatus, which delivers complete barrier protection and independent breathing air in hazardous atmospheres. This is why it’s chosen as the correct option: it provides maximum protection for both skin and respiratory tract, crucial when there’s any risk of splash or inhalation of toxic agents. Other configurations use non-encapsulating suits or rely on air-purifying respirators, which do not provide the same level of skin sealing or independent air supply.
