10.3 Where can I find occupational exposure limits? (Chemical Safety)
There are several organisations responsible for establishing the
occupational exposure limits. The values used most extensively in industry,
but also the most controversial, are those of the ACGIH. Their TLVs and
Biological Exposure Indices [8] have been used in many countries as initial
guidelines until relevant local expertise can assess their suitability.
They are also misused, despite the clear warnings in the front of the
booklet.
The US Government also has Permissible Exposures Limits set by the Dept. of
Labor Occupational Safety and Health Administration, and Recommended
Exposure Limits set by the US National Institute for Occupational Safety and
Health. The Deutsche Forschungsgemeinschaff Maximum Concentrations in the
Workplace are often also used. The ACGIH publishes an excellent compilation
of all these limits [9], thus facilitating a review of how experts perceive
the occupational hazards. The International Labour Office in Geneva
publishes a comprehensive " Encyclopedia of Occupational Health and Safety "
which also covers chemicals [10].
