ACGIH publications

According to the ACGIH publication (O the STEL should be considered a maximal allowable concentration, or ceiling, not Do be exceeded at any time during a 15-minute excursion period. The average time spent treating any one residential site was approximately six minutes. 

Documentation of the Threshold Limit Values and Biological Exposure Indices, 7th Edition, ACGIH Publications, Cincinnati, OH, USA, 2001. 

An ACGIH publication summarises toxicological information on substances for which TLVs have been adopted and shows that for some substances the hazards are clear, whereas for others there is very little information on human danger. This inherent uncertainty is not reflected in the bland listing of adopted values.

The American Conference on Government Industrial Hygienists (ACGIH) is a member-based organization that advances occupational and environmental health (ACGIH 2007). An example of this includes the annual publication of the Threshold Limit Values (TLVs) and Biological Exposure Indices (BEls) recommended for chemical substances. 

TLVs are revised by the ACGIH annually as new information becomes available. Each year, additional substances of interest are added to the TLV list. Certain compounds that are proven or suspected carcinogens in humans such as benzidine, 4-aminodiphenyl, and 4-nitrodiphenyl have no TLV value, and human exposure to these agents should be avoided. Note For a detailed discussion of carcinogenic risks to humans, the publications of the lARC should be consulted. 

The first occupational safety and health standards were set when, with only minor changes, the 1968 ACGIH list of nearly 400 TLVs, as well as certain standards of the American National Standards Institute (ANSI), were incorporated into the Walsh-Healey Public Contracts Act. They thereby became limits of exposure for employees of federal government contractors.

The latest annual TLV list is contained in the publication Threshold Limit Values and Biological Exposure Indices. This publication should be consulted for future trends in recommendations. The ACGIH TLVs are adopted in whole or in part by many countries and local administrative agencies throughout the world. As a result, these recommendations have a major effect on the control of workplace contaminant concentrations. The ACGIH may be contacted for additional information at Kemper Woods Center, 1330 Kemper Meadow Drive, Cincinnati, OH 45240. 

A gas data and safety sheet for carbonyl difluoride has been produced by the British Compressed Gases Association [277] and the compound is described in the Matheson publication, "Guide to safe handling of compressed gases [1347], and the ACGIH Documentation of the Threshold Limit Values for Substances in Workroom Air [38,39]. 

Extrapolation to a practical threshold or subthreshold dose, such as the determination of a reference dose [RfD, e.g., EPA s perchlorate (ERA 2009b)] or tolerable daily intake [TDl, e.g.. The Netherlands s National Institute for Public Health and the Environment or RIVM s trichloroethylene (RIVM 2009)], or development of health-based occupational exposure limits by many gronps [e.g., American Conference of Governmental Industrial Hygienists (ACGIH 2006)].
