Development of a chronic inhalation reference level for respirable crystalline silica
Communicate and train employees on the hazards associated with crystalline silica
under the Hazard Communication Standard and ensure that each employee has access to labels on containers of crystalline silica
and safety data sheets.
OSUA first established a maximum permissible exposure level for crystalline silica
in 1970 by adopting a consensus industry standard.
The OSHA illness and injury reporting improvements are probably less significant than the potential lowering of the crystalline silica
OSHA's proposals to reduce the permissible exposure limit for crystalline silica
and to require certain companies to provide quarterly recordkeeping updates to OSHA--which may make them publicly available-are two game changing initiatives.
SIMON Ellis, a respiratory disease solicitor at Hugh James, discusses how exposure to crystalline silica
dust through working with fine particles of sand, cement or limestone may be the emerging respiratory disease in the workplace.
It is also a replacement for silica sands, utilized in sandblasting, since it produces non-detectable or lower levels of airborne crystalline silica
However, a study by the National Institute of Occupational Safety and Health (NIOSH) found that workers at 11 hydraulic fracturing sites in five states were exposed to high levels of crystalline silica
That sandstone contains a particularly pure form of crystalline silica
Estimating respirable crystalline silica
exposures for Chinese pottery workers and Iron/Copper, Tin, and Tungsten Miners.
The pneumoconioses are a group of irreversible but preventable interstitial lung diseases, most commonly associated with inhalation of asbestos fibers, coal mine dust, or crystalline silica
Though there is no hard scientific evidence linking cement dust to TB, studies have shown that persons with silicosis -- a lung disease caused by inhalation of crystalline silica
dust, often caused by occupational exposure -- are up to 30 times more likely to develop TB.
