What is a characteristic of PPE Level C?

A characteristic of PPE Level C is the use of air-purifying respirators along with chemical-resistant clothing. This level of personal protective equipment is designed for situations that involve airborne contaminants where the concentration is known and has been evaluated, allowing for the use of air-purifying respirators that filter out harmful substances. Chemical-resistant clothing provides a barrier to protect the skin from potential splashes or hazardous materials, which is crucial when dealing with certain chemicals or substances in a controlled environment.

This level of PPE is typically used when the chemical exposure is identified but not expected to be life-threatening, contrasting with Level A or B PPE, which involve more extensive respiratory protection or protective suits for harsher conditions. Therefore, the combination of air-purifying respirators and chemical-resistant clothing reflects the appropriate protective measures for moderate hazard scenarios.
