Dust and fumes from processing: Health effects from mechanical processing (e.g., cutting, grinding): Dust: Can cause irritation of the eyes, skin and respiratory
tract. Chronic overexposures: Can cause reduction in the number of red blood cells and skin abnormalities.
Additional health effects from elevated temperature processing (e.g., welding, melting): Dust and fume from processing: Acute overexposure: Can cause metal
fume fever (nausea, fever, chills, shortness of breath and malaise), reduced ability of the blood to carry oxygen and the accumulation of fluid in the lungs. Chronic
overexposures: Can cause scarring of the lungs, central nervous system damage, secondary Parkinson's disease, respiratory sensitisation, reproductive harm
and lung cancer.
Contains nickel. May produce an allergic reaction.
Contact with residual oil/oil coating: Prolonged or repeated skin contact may cause sensitisation and allergic contact dermatitis.
This product does not present fire or explosion hazards as shipped. Small chips, fine turnings, and dust from processing may be readily ignitable.
Explosion/fire hazards may be present when:
• Dust or fines are dispersed in air.
• Dust and fines in contact with water can generate flammable/explosive hydrogen gas. These gases could present an explosion hazard in confined or poorly
ventilated spaces.
• Dust and fines are in contact with certain metal oxides (e.g., rust, copper oxide).
• Molten metal in contact with water/moisture or certain metal oxides (e.g., rust, copper oxide).
FIRE FIGHTING MEASURES: Use Class D extinguishing agents on fines, dust or molten metal. Use coarse water spray on chips and turnings.
DO NOT USE water in fighting fires around molten metal. DO NOT USE halogenated extinguishing agents on small chips/fines. These fire extinguishing agents
will react with the burning material.
IN CASE OF SPILL: Avoid dust formation. Collect scrap for recycling. If molten: Use dry sand to contain the flow of material. All tooling (e.g., shovels or hand
tools) and containers which come in contact with molten metal must be preheated or specially coated, rust free and approved for such use. Allow the spill to cool
before remelting as scrap.
