Level C protection consists of which of the following?

Level C protection is designed for situations where the contaminants are known and the air concentration levels are not immediately hazardous to life or health, but there is still a potential for exposure. This level of protection is characterized by the use of appropriate respiratory protection and protective clothing.

In this context, a full-face air-purifying respirator is crucial because it provides protection against inhaling harmful vapors or particulates, ensuring that the user can safely breathe while working in contaminated environments. The inclusion of splash clothing further enhances safety by protecting the skin from chemical splashes, thus minimizing dermal exposure to hazardous materials. This combination allows responders to work effectively in situations where they need both respiratory and skin protection.

The other options involve either more extensive protection than necessary for Level C, like the full-body encapsulating suit, or insufficient protection, such as a simple surgical mask which does not provide adequate respiratory protection against hazardous materials. Consequently, the correct combination for Level C protection is a full-face air-purifying respirator along with splash clothing.
