PEL stands for Permissible Exposure Limit and is the OSHA standard, the same as TLV/TWA.

• A. Permissible Exposure Level
• B. Permissible Exposure Limit, OSHA standard, same as TLV/TWA
• C. Peak Exposure Limit
• D. Protective Exposure Level

Answer: (C)

PEL stands for Permissible Exposure Limit, the maximum exposure level allowed by OSHA and enforced as a regulation. This value is a legal limit that applies in workplaces, and it is not simply a guideline. TLV/TWA, on the other hand, comes from the American Conference of Governmental Industrial Hygienists (ACGIH) as threshold values and time-weighted averages used for guidance, not as enforceable OSHA limits. They can be similar to PELs in some cases, but they are not the same thing and are not automatically legally binding. The term that some options imply as a synonym—like “Peak Exposure Limit”—is not a standard OSHA concept for PELs, and other proposed expansions (Permissible Exposure Level, Protect ive Exposure Level) do not reflect the official terminology.
