What is OSHA’s standard permissible exposure limit or PEL?
The current PEL for OSHA standards are based on a 5 decibel exchange rate. OSHA’s PEL for noise exposure is 90 decibels (dBA) for an 8-hour TWA. Levels of 90-140 dBA are included in the noise dose. PEL can also be expressed as 100 percent “dose” for noise exposure.
What is the OSHA PEL TWA for the respirable fraction of kaolin dust?
The Agency proposed an 8-hour TWA PEL of 10 mg/m3 for kaolin, and the final rule establishes this limit; the 5-mg/m3 limit for the respirable fraction is retained. Kaolin may be a white powder, or a white or yellow-white, earthy mass.

What is the difference between TWA and PEL?
A Time Weighted Average (TWA) is a TLV(R) based on a 8-hour workday and a 40-hour workweek. The Permissible Exposure Limit (PEL or OSHA PEL) is a TLV(R) established by OSHA in the U S for exposure of an employee to a substance or physical agent, and may differ from TLVs(R) in other jurisdictions.
