BRASS AND BRONZE ALLOYS

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Solid. Bronze color. Odorless. 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 dust clouds are dispersed in the air. * Molten metal is in contact with water/moisture. Dust and fume from processing can cause irritation of eyes, skin and upper respiratory tract and metal fume fever.

Potential health effects

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 The health effects listed below are not likely to occur unless processing or recycling/combustion generate dusts or fumes. Eyes Dust or fume from processing: Can cause irritation. Skin Dust or fume from processing: Can cause irritation, sensitization and discolorations. Ingestion Dust or fume from processing: Can cause irritation, abnormal heart rhythms (arrhythmia) and central nervous system effects. Inhalation from mechanical processing (e.g., cutting, grinding) Can cause upper respiratory tract irritation Chronic overexposures: Can cause reduction in the number of red blood cells (anemia) and skin abnormalities (pigmentation changes), scarring of the lungs (pulmonary fibrosis), lung damage, respiratory sensitization, central nervous system damage, secondary Parkinson's disease and reproductive harm. Additional health effects from elevated temperature processing (e.g., welding, melting): Acute overexposures: Can cause nausea, fever, chills, shortness of breath and malaise (metal fume fever). Chronic overexposures: Can cause lung cancer. Carcinogenicity and Reproductive Hazard Product as shipped: Does not present any cancer or reproductive hazards. Dust and fumes from mechanical processing: Can present a cancer hazard (lead, nickel, antimony trioxide). Can present a reproductive hazard (manganese, lead). Dust and fumes from welding or elevated temperature processing: Can present a cancer hazard (nickel compounds). Can present a reproductive hazard (manganese, lead).

Medical Conditions Generally Aggravated by Exposure

to Product, Components or Compounds Formed During Processing Dust or fume from processing: Asthma, chronic lung disease, skin rashes and secondary Parkinson's disease.
