Which PPE level includes a full face piece SCBA and hooded chemical resistant clothing?

The correct answer is that PPE Level B includes a full face piece self-contained breathing apparatus (SCBA) and hooded chemical resistant clothing. This level of personal protective equipment is designed for situations where a high level of respiratory protection is necessary, but the chemical threat is not as severe as that which would necessitate the use of PPE Level A.

Level B is utilized when the concentration and type of airborne contaminants are known, and when physical hazards are present, but the level of chemical exposure does not require the use of totally encapsulating suits. The full face piece SCBA provides both respiratory protection and face protection, making it suitable for environments with harmful gases, vapors, or particulates.

In contrast, PPE Level A offers the highest level of skin, respiratory, and eye protection, typically requiring fully encapsulated suits and specific respiratory protection for handling highly hazardous materials. PPE Level C provides a lower level of protection where the airborne concentration of contaminants is known and is being monitored, but not requiring the same complexity and risk mitigation as Level B. Meanwhile, PPE Level D is designed for minimal hazards and requires the least amount of protective equipment, typically not involving respirators.
