DEFINITIONS OF TERMS (Continued)
EXPOSURE LIMITS IN AIR (continued):
PEL-Permissible Exposure Limit: OSHA’s Permissible Exposure Limits. This exposure value means
exactly the same as a TLV, except that it is enforceable by OSHA. The OSHA Permissible Exposure Limits
are based in the 1989 PELs and the June, 1993 Air Contaminants Rule (Federal Register: 58: 35338-35351
and 58: 40191). Both the current PELs and the vacated PELs are indicated. The phrase, “Vacated 1989
PEL,” is placed next to the PEL that was vacated by Court Order.
SKIN: Used when a there is a danger of cutaneous absorption.
STEL-Short Term Exposure Limit: Short Term Exposure Limit, usually a 15-minute time-weighted
average (TWA) exposure that should not be exceeded at any time during a workday, even if the 8-hr TWA
is within the TLV-TWA, PEL-TWA or REL-TWA.
TLV-Threshold Limit Value: An airborne concentration of a substance that represents conditions under
which it is generally believed that nearly all workers may be repeatedly exposed without adverse effect.
The duration must be considered, including the 8-hour.
TWA-Time Weighted Average: Time Weighted Average exposure concentration for a conventional 8-
hr (TLV, PEL) or up to a 10-hr (REL) workday and a 40-hr workweek.
HAZARDOUS MATERIALS IDENTIFICATION SYSTEM

anticipated. Skin Irritation: Essentially non-irritating. PII or Draize = “0”. Eye Irritation: Essentially non-
