Section 11 - Toxicological Information
ROUTE OF EXPOSURE
Skin Contact: May cause skin irritation.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: May cause eye irritation.
Inhalation: Harmful if inhaled. Material is irritating to mucous
membranes and upper respiratory tract.
Ingestion: May be harmful if swallowed.
TARGET ORGAN(S) OR SYSTEM(S)
Lungs.
SIGNS AND SYMPTOMS OF EXPOSURE
Prolonged inhalation of crystalline silica may result in
silicosis, a disabling pulmonary fibrosis characterized by
fibrotic changes and miliary nodules in the lungs, a dry cough,
shortness of breath, emphysema, decreased chest expansion, and
increased susceptibility to tuberculosis. In advanced stages,
loss of appetite, pleuritic pain, and total incapacity to work.
Advanced silicosis may result in death due to cardiac failure or
destruction of lung tissue. Crystalline silica is classified as
group 1 "known to be carcinogenic to humans" by IARC and
"sufficient evidence" of carcinogenicity by the NTP. To the best
of our knowledge, the chemical, physical, and toxicological
properties have not been thoroughly investigated.
