Which level of PPE includes a fully encapsulating suit and SCBA?

The correct answer is the level of PPE that includes a fully encapsulating suit and a self-contained breathing apparatus (SCBA) is Level A. This level of personal protective equipment is designed for situations where the highest level of protection is necessary. A fully encapsulating suit provides a complete barrier against hazardous materials, ensuring that no contaminants can penetrate the suit and reach the individual wearing it.

Level A PPE is utilized in environments where the type and exposure to hazardous materials are unknown or when they present a high risk. The inclusion of an SCBA is critical in these scenarios because it supplies breathable air in an oxygen-deficient atmosphere or a potentially harmful gas environment. Thus, Level A PPE ensures full-body protection and a safe breathing supply, making it the most protective option available for responders to use in hazardous material situations.

Other levels of PPE, such as Level B, Level C, and Level D, provide varying degrees of protection and are suitable for different types of exposures, but none offer the same comprehensive coverage and respiratory protection as Level A.
