SECTION 2: Hazards identification

Acute INGESTION: Non-toxic by ingestion. Swallowing a large amount may result in irritation to the digestive system due to abrasiveness. EYE CONTACT: Solids and dust of dried product can be irritating due to abrasiveness. SKIN CONTACT: Can cause skin irritation due to abrasiveness INHALATION: As shipped from the manufacturer, the grain size of the product is outside the respirable range (>10um diameter) and precludes it from being an inhalation hazard. Handling and processing can however fracture grains, and in the dry state this can generate dust. It can be irritating if inhaled at high concentration. May cause symptoms such as coughing or sneezing. Chronic General The main exposure route to the constituents in Staurolite Concentrate is dust inhalation. Silica Crystalline silica is a know cause of lung fibrosis (silicosis). It has also been classified as a human carcinogen. (International Agency for Research on Cancer). Staurolite concentrate contains quartz, (up to 1%) and precautions should be taken to avoid inhaling the dust., Uranium Thorium As is common with many minerals, Staurolite Concentrate contains very low levels (below 0.05% by weight) of naturally occurring radioactive elements of the uranium and thorium series. Internal exposure via inhaled dust is the main exposure. Close proximity to large quantities (bulk or stockpiles) of staurolite concentrate over long periods (2000 hours per year) may result in direct exposure. This Staurolite concentrate is exempt from the NRC regulations for source material per 10 CFR40 because it is below the 0.05% uranium and thorium.
