Does OSHA require respirator use when asbestos is removed?
In this regard, the statement in the December 14, 1998 letter to you from Mr. Gilbert J. Gillotti that "OSHA does not base the requirements for respiratory protection or PPE on asbestos content" is not entirely accurate. Airborne asbestos fiber concentrations during Class II removal activities will vary widely and may well exceed permitted limits if the material is not substantially intact when removed or the removal is not performed using wet methods. For that reason, the standard requires respirator use without regard to measured airborne levels when asbestos-containing material (i.e., material containing more than 1% asbestos) is not removed in a substantially intact state or is not removed using wet methods.
Overview
History
People have used asbestos for thousands of years to create flexible objects that resist fire, including napkins, but, in the modern era, companies began producing consumer goods containing asbestos on an industrial scale. Today people recognize the health hazard that asbestos poses; the use of asbestos is completely banned in 55 countries and strictly regulated in many others.
Etymology
The word "asbestos", first used in the 1600s, ultimately derives from the Ancient Greek: ἄσβεστος, meaning "unquenchable" or "inextinguishable". The name reflects use of the substance for wicks that would never burn up.
It was adopted into English via the Old French abestos, which in turn got the word from Greek via Latin, but in the original Greek, it actually referred to quicklime. It is said by the Oxford English Dic…
Types and associated fibers
Six mineral types are defined by the EPA as "asbestos" including those belonging to the serpentine class and those belonging to the amphibole class.
