Chemical Exposure Limits
Description:
Recommended or mandatory occupational exposure limits (OELs) have been developed in many countries for airborne exposure to gases, vapours and particulates. The most widely used limits, called threshold limit values (TLVs), are those issued in the United States of America by the American Conference of Governmental Industrial Hygienists (ACGIH).
Why this Tool/Guidance?
This guidance helps countries with implementation of occupational exposure limits in their occupational health system.
