77710 - Epirok Aggregate Mix No. 1

SECTION 2: Hazards identification

Emergency Overview: The material is an off-white aggregate. It is not flammable, combustible or explosive. It does not cause burns or severe skin or eye irritation. A single exposure will not result in serious adverse health effects. Crystalline silica (quartz) is not known to be an environmental hazard. Crystalline silica (quartz) is incompatible with hydrofluoric acid, fluorine, chlorine tri-fluoride or oxygen di- fluoride.

Potential health effects

Skin Contact: Not applicable. Inhalation  Silicosis: Respirable crystalline silica (quartz) can cause silicosis, a fibrosis (scarring) of the lungs. Silicosis may be progressive; it may lead to disability and death.  Cancer: Crystalline silica (quartz) inhaled from occupational sources is classified as carcinogenic to humans.  Autoimmune Disease: There are some studies that show excess numbers of cases of scleroderma and other connective tissue disorders in workers exposed to respirable crystalline silica.  Tuberculosis: Silicosis increases the risk of tuberculosis.  Nephrotoxicity: There are some studies that show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crystalline silica (quartz). Eye Contact: Crystalline silica (quartz) may cause abrasion of the cornea. Ingestion: Not applicable.

Potential chronic health

The adverse health effects caused by chronic exposure include: silicosis, cancer, autoimmune diseases, tuberculosis and nephrotoxicity. Signs and Symptoms of Exposure: Generally, there are no signs or symptoms of exposure to crystalline silica (quartz).

Medical Conditions Generally Aggravated by Exposure

The condition of individuals with lung disease (e.g. bronchitis, emphysema, chronic obstructive pulmonary disease) can be aggravated by exposure. See section 11, Toxicological Information, for additional details on potential adverse health effects.
