Short-term exposure limit : ウィキペディア英語版 | Short-term exposure limit A short-term exposure limit (STEL) is the acceptable average exposure over a short period of time, usually 15 minutes as long as the time-weighted average is not exceeded. STEL is a term used in occupational health, industrial hygiene and toxicology. The STEL may be a legal limit in the United States for exposure of an employee to a chemical substance. The Occupational Safety and Health Administration (U.S. OSHA) has set OSHA-STELs for 1,3-Butadiene,〔(29CFR1910.1051 )〕 benzene 〔(29CFR1910.1028 )〕 and ethylene oxide.〔(29CFR1910.1047 )〕 For chemicals, STEL assessments are usually done for 15 minutes and expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg/m3). The American Conference of Governmental Industrial Hygienists publishes a more extensive list of STELs as threshold limit values (TLV-STEL).〔(American Conference of Governmental Industrial Hygienists )〕 == Similar national exposure limits ==
