The Answer is AL

\quad

“Action Level” The purpose is to set a trigger level at one-half the legal PEL limit so that employers will respond to dangers before the employee is exposed to levels at or near the legal limit (the PEL).

C

\quad

“Ceiling Level” The purpose is to set a standard beyond which employees should not be exposed, even for a little while. The time-weighted-average (TWA) is not appropriate when the OSHA table lists the PEL as a “ceiling value.” (Ceiling values are indicated by the letter C adjacent to the PEL as shown in Appendix A.1)

TWA

\quad

“Time-Weighted Average” Refers to a standard for average exposure during a full eight-hour shift. PELs are usually stated as TWAs, but may be stated as C for “ceiling level” exposure.

PEL

\quad

“Permissible Exposure Level” A maximum exposure level as stated in a regulatory standard. PELs are usually stated as TWAs, but may be stated as C for “ceiling level” exposure. PELs are usually derived from accepted TLVs.

TLV

\quad

“Threshold Limit Value” For a give contaminant, a level of exposure below which the contaminant is believed not to be harmful. Although public and scientific opinion may vary on what level of contaminant exposure is harmful, the American Conference of Governmental Industrial Hygienists (ACGIH) publishes a list of TLVs considered to be appropriate. TLVs are not legally enforceable, but PELs can be derived from published TLVs. Like PELs, TLVs are usually stated as TWAs, but they may be stated as ceiling values (C).
