Industrial hygiene time-weighted average

AIHA WEEL American Industrial Hygiene Association recommended Workplace Environmental Exposure Levels based on a time-weighted average exposure over an 8-h period and 40-h work week. [Pg.796]

HFC-134a is a relatively new chemical, and only the American Industrial Hygiene Association (AIHA 1991) has developed a workplace guideline. The AIHA Workplace Environmental Exposure Level (WEEL) of 1,000 ppm is an 8-h time-weighted average. The German MAK and Dutch MAC are also 1,000 ppm (German Research Association 1999 Ministry of Social Affairs and Employment 2000). [Pg.169]

The American Industrial Hygiene Association s (AIHA) Workplace Environmental Exposure Level Committee gave HFC-134a an occupational exposure limit (8-hr time-weighted average) of 4,250 mg/m3 (AIHA 1991, as cited in European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) 1995).
