What does Level B protection consist of?

• A. Basic work uniform with minimal protection
• B. Fully encapsulating suit with SCBA inside
• C. Splash-protective suit with SCBA worn outside the suit
• D. Standard work clothing with APR respirator

Answer: (C)

Level B protection is characterized by the use of a splash-protective suit that does not fully encapsulate the body, combined with a Self-Contained Breathing Apparatus (SCBA) worn outside the suit. This level of protection is utilized in situations where the primary hazard is the potential for splashes or exposure to hazardous liquids, but where a high level of respiratory protection is still critical due to the risk of airborne contaminants.

The splash-protective suit provides a physical barrier against chemical exposure, while the SCBA ensures that the wearer has a safe supply of breathable air, thereby protecting against inhalation of harmful substances. The external positioning of the SCBA allows for easier access and maintenance, which is particularly important in hazardous environments.

This combination makes Level B suitable for operations where the risk of exposure necessitates protection for both the skin from hazardous liquids and the respiratory system from toxic gases or vapors.
