Level C protection includes which type of protective measures?

• A. Fully encapsulating suit with SCBA
• B. Basic work uniform without special protection
• C. Standard work clothing with APR or PAPR respirator
• D. Splash-protective suit

Answer: (C)

Level C protection is characterized by the use of standard work clothing in conjunction with respiratory protection. This level of protection is suitable for situations where the contaminant is known, air monitoring indicates that the air is safe to breathe except for the presence of gases or vapors, and where splashes or immersion in hazardous materials are not anticipated.

The inclusion of either an Air Purifying Respirator (APR) or a Powered Air Purifying Respirator (PAPR) is critical in Level C attire. These respirators are designed to filter out specific contaminants from the air, thereby providing adequate respiratory protection for workers when handling chemicals or in environments where exposure is a concern.

In contrast to other options, a fully encapsulating suit with SCBA, a basic work uniform, or a splash-protective suit would not correctly represent Level C protection. The fully encapsulating suit is used in Level A protection, which is for the highest levels of exposure. A basic work uniform lacks any special protection and would not be adequate for hazardous material environments, and while splash-protective suits offer some level of protection against liquids, they do not include the necessary respiratory protection that characterizes the Level C ensemble.
