SECTION 2: Hazards identification

Emergency Overview: Solid. Gold-yellow or reddish color. Odorless. Non-combustible as supplied. 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 Section 11. 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. Inhalation from mechanical processing (e.g., cutting, grinding) Can cause irritation of upper respiratory tract Acute overexposures Can cause nausea and muscle cramps. Chronic overexposures Can cause reduction in the number of red blood cells (anemia), skin abnormalities (pigmentation changes), central nervous system damage, respiratory sensitization, scarring of the lungs 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) and central nervous system effects. 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). Can present a reproductive hazard (lead). Dust and fumes from welding or elevated temperature processing: Can present a cancer hazard (nickel compounds, lead compounds, welding fumes). Can present a reproductive hazard (lead).

Medical Conditions Generally Aggravated by Exposure

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