Precautionary statements

DANGER! May cause cancer through inhalation of dust. Obtain special instructions before use. May damage fertility or the unborn child. Do not handle until all safety precautions have been Causes damage to the respiratory system through prolonged read and understood. or repeated inhalation of fine dust. Do not breathe dust. Harmful to aquatic life with long lasting effects. Wear protective gloves, protective clothing, eye protection and respiratory protection. Wash hands thoroughly after handling. Do not eat, drink or smoke when using this product. Avoid release to the environment. If exposed or concerned or you feel unwell: Get medical advice/attention. Emergency Overview: A dark brown, heavy, soil-like material that is not flammable or combustible under normal conditions of transport and storage. However, when heated strongly in air it will burn, releasing toxic and irritating sulphur dioxide gas as well as possible lead and zinc oxide fumes. Contact with strong acids will generate flammable and highly toxic hydrogen sulphide gas (H2S). Inhalation or ingestion of concentrate dust may produce chronic health effects. Possible cancer hazard due to lead, cadmium and silica content. Possible reproductive hazard due to the lead content. SCBA and full protective clothing required for fire emergency response personnel, especially due to the potential for release of highly irritating SO2 gas in a fire situation.

Potential health effects

Caution The toxicological properties of this material have not been fully investigated. The information contained in this SDS is therefore based on information in the technical and scientific literature about the material’s constituent compounds. Concentrate dust is irritating to the nose, throat and respiratory tract. Inhalation or ingestion of very high concentrations of concentrate dust may result in lead and cadmium absorption and possible lead intoxication. Symptoms include headache, nausea, vomiting, abdominal spasms, fatigue, sleep disturbances, weight loss, anemia and leg, arm, and joint pain. Prolonged exposure may also cause central nervous system damage (e.g., fatigue, headaches, tremors, hypertension), gastrointestinal disturbances, anemia, kidney dysfunction and possible reproductive effects. Pregnant women should be protected from excessive exposure to prevent lead crossing the placental barrier and causing infant neurological disorders. Lead and lead compounds are listed as an A3 Carcinogen (Confirmed Animal Carcinogen with Unknown Relevance to Humans) by the ACGIH. IARC has listed lead compounds as Group 2A Carcinogens (Probably Carcinogenic to Humans). Cadmium is classified as an A2 Carcinogen by the ACGIH and as a Group 1 Carcinogen by IARC. Silica is classified as an A2 Carcinogen by the ACGIH and as a Group 1 Carcinogen by IARC (see Toxicological Information, Section 11).

Environmental effects

Zinc concentrate will likely have minimal direct environmental effects, since its constituent metals have low solubility, and are therefore not highly bioavailable. However, when the product is processed or resides in the environment for extended periods, compound forms of zinc and lead may form which are potentially toxic to aquatic and terrestrial organisms (see Ecological Information, Section 12).
