OSHA Specifically Regulated Substances (29 CFR 1910.1001-1050)
Not listed.
Reproductive toxicity
No data available, but none expected.
Specific target organ toxicity -
single exposure
No data available, but none expected.
Specific target organ toxicity -
repeated exposure
May damage lung tissue through repeated and prolonged exposure to high levels of respirable
crystalline silica particles.
Aspiration hazard
Due to the physical form of the product it is not an aspiration hazard.
Chronic effects
Prolonged and routine inhalation of high levels of respirable crystalline silica particles can lead to
the lung disease known as silicosis. Some studies show excess numbers of cases of
scleroderma, connective tissue disorders, lupus, rheumatoid arthritis, chronic kidney diseases and
end-stage kidney disease in workers exposed to respirable crystalline silica. Pre-existing skin and
respiratory conditions including dermatitis, asthma and chronic lung disease might be aggravated
by exposure. Occupational exposure to respirable dust and respirable crystalline silica should be
monitored and controlled.
