Which level of PPE is the lowest level of protection?

Level D PPE represents the lowest level of personal protective equipment available in hazardous materials response. This level of protection is characterized by minimal risk and is typically used in situations where there is no threat of exposure to hazardous materials. Level D gear generally consists of standard work uniforms (like coveralls) and may include gloves and safety glasses, providing basic protection against non-hazardous environments or situations with minimal risk of exposure.

In contrast, Level A PPE offers the highest level of protection, including fully encapsulated suits, while Level B provides high protection but is not fully encapsulated. Level C PPE is typically used when the concentration and type of airborne substances are known and it is suitable for the operation. Each of these levels is designed for specific scenarios and potential threats, making it crucial for responders to select the appropriate level of PPE based on the hazards present.
