Which level would be chosen when chemical hazards are present but respiratory hazards are not severe?

• A. Level A
• B. Level B
• C. Level C
• D. Level D

Answer: (C)

The key idea here is choosing PPE based on the type and severity of hazards. When chemicals are present but the respiratory danger isn’t severe, you don’t need the most protective, fully encapsulating options. Level C uses an air-purifying respirator for breathing protection and chemical-resistant clothing for skin protection, which is enough to handle known chemical contaminants while still allowing mobility. It also assumes there’s enough oxygen in the surroundings for the respirator to work.

Level A would be used only when the atmosphere is highly unknown or extremely toxic and requires a fully encapsulating suit with a supplied-air respirator. Level B provides stronger skin and splash protection with a respirator, but relies on SCBA for breathing, which isn’t necessary here. Level D is just basic work attire with minimal protection, inappropriate when chemical exposure is possible. Level C is the best fit because it protects against chemicals without the excessive escalation needed for severe or unknown respiratory hazards.
