BRASS AND BRONZE ALLOYS

SECTION 2: Hazards identification

Emergency overview Solid. Odorless. Bronze - Metallic. Non-combustible as supplied. Small chips, fine turnings and dust from processing may be readily ignitable. Explosion/fire hazards may be present when (See Sections 5, 7 and 10 for additional information): • Heavily concentrated dusts in air can be explosive if subjected to a strong ignition source. • Contact of molten metal with water or moisture can result in a rapid generation of steam which may produce a violent splattering of molten metal.

Potential health effects

from mechanical processing (e.g., cutting, grinding) Dust Can cause irritation of the eyes, skin and upper respiratory tract. Additional health effects from elevated temperature processing (e.g., welding, melting): Dust and fumes Can cause irritation of the eyes, skin and respiratory tract. Acute overexposures Can cause nausea, fever, chills, shortness of breath and malaise. The following statements summarize the health effects generally expected in cases of overexposures. User specific situations should be assessed by a qualified individual. Additional health information can be found in Section 11. The health effects listed below are not likely to occur unless processing of this product generates dusts or fumes. Eyes Dust and fumes from processing Can cause irritation. Skin Direct contact Can cause irritation. Prolonged or repeated skin contact may cause skin abnormalities (pigmentation changes) and sensitization Inhalation Health effects from mechanical processing (e.g., cutting, grinding) Dust Can cause irritation of the upper respiratory tract. Chronic overexposures: Can cause reduction in the number of red blood cells (anemia), skin abnormalities (pigmentation changes), respiratory sensitization, scarring of the lungs (pulmonary fibrosis), central nervous system damage, secondary Parkinson's disease and reproductive harm. Additional health effects from elevated temperature processing (e.g., welding, melting): Dust and fumes Can cause irritation of the respiratory tract. Acute overexposures Can cause nausea, fever, chills, shortness of breath and malaise (matal fume fever). Chronic overexposures: Can cause lung cancer. Carcinogenicity and Reproductive Hazard Product as shipped: Does not present any cancer or reproductive hazards. Dust from mechanical processing: Can present a cancer hazard (Lead, Nickel). Can present a reproductive hazard (Lead, Manganese). Dust and fumes from welding or elevated temperature processing: Can present a cancer hazard (Antimony trioxide, Lead compounds, Nickel compounds). Can present a reproductive hazard (Lead compounds, Manganese compounds). Medical conditions aggravated by exposure to product Dust and fumes from processing: Asthma, chronic lung disease, Secondary Parkinson's disease and skin rashes.
