What are the 4 levels of PPE?

PPE falls into four categories depending on the level of protection it provides. These are levels A, B, C, and D dangers. When the highest degree of skin, respiratory, and eye protection is needed, choose Level A.

What is the difference between Level B and Level C PPE?

Skin protection is the same as that of Level B but the respiratory protection is lower at Level C. Chemical splash protection is provided by the chemical protective suit, however, vapor or gas protection is not. In terms of worker safety, degree C is the most often employed level of protection.

Which organization must certify the SCBA?
