Which PPE level is typically used for nonhazardous environments?

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

Answer: (C)

In nonhazardous environments, you aim for protection that covers basic safety without getting in the way. Level D provides that balance: standard work clothing with basic safeguards such as eye protection and gloves as needed, and no respirator or chemical barriers. Higher levels are designed for atmospheres with unknown or high-risk contaminants, requiring specialized suits or respirators—Level A is a fully encapsulated suit with SCBA, Level B offers strong skin and splash protection with SCBA, and Level C uses a respirator with protective clothing for known contaminants that can be filtered. Because nonhazardous settings don’t demand those protections, Level D is the typical choice. If hazards arise, you would escalate to a higher level accordingly.
