What is an OSHA ceiling limit?

Ceiling limit: The maximum exposure limit, which cannot be exceeded for any length of time. A PEL may be calculated on average exposure throughout the day (TWA) or on the amount that’s not safe for more than a short period of time (STEL).

The permissible exposure limit (PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent. Permissible exposure limits are established by the Occupational Safety and Health Administration (OSHA).

What is the difference between PELs and TLVs?

PELs are legal limits, meaning OSHA can enforce their use and any non-compliance in the United States. In contrast, TLVs are recommendations. Although ACGIH is a well-known and respected scientific organization that contributes to the PELs set by OSHA, its TLVs are not legal limits.

How are PELs determined?

To ascertain whether an employee is exposed above the regulatory limit for a contaminant that has a ceiling value, use Table Z-2 to determine the PEL. Please note that a short-term exposure limit addresses the average exposure during a 15- to 30-minute period of maximum exposure in a single work shift.

What is the difference between STEL and TWA?

A Time Weighted Average (TWA) is a TLV(R) based on a 8-hour workday and a 40-hour workweek. A Short Term Exposure Limit (STEL) is a TLV(R) based on a 15 minute average. A Ceiling is a TLV that should not be exceeded during any part of the work experience.

What is the difference between OEL and PEL?

OEL = Occupational Exposure Limit. PEL = Permissible Exposure Limit.

Are OSHA PELs legally enforceable?

Cal/OSHA PELs are promulgated under statutory requirements for risk and feasibility that are no less protective than the OSH Act. Though not enforceable in establishments outside of Cal/OSHA’s jurisdiction, the PELs can provide information on acceptable levels of chemicals in the workplace.
