Warning Statements: NOT FLAMMABLE IN INGOT FORM. HOWEVER, UNDER EXTREME FIRE CONDITIONS, MAY REACT WITH WATER TO PRODUCE FLAMMABLE, EXPLOSIVE HYDROGEN GAS. FINE DUSTS IN HIGH CONCENTRATIONS ARE IGNITABLE AND MAY CAUSE SKIN, EYE AND RESPIRATORY TRACT IRRITATION. NOTE: For purposes of this MSDS, occupational exposure to metals or alloys is taken to mean dusts, fumes, or solutions containing metals that become airborne or can spill on the skin or in the eye. Occupational exposure to metals or alloys does not include solid products (i.e., ingots or castings), provided no particle generating operations, such as grinding or cutting, occur. In most industrial situations, the significant routes of exposure would include inhalation, or skin and eye contact. B. POTENTIAL HEALTH EFFECTS: Acute Eye: May cause irritation. Acute Skin: Skin absorption not likely. May cause irritation. Acute Inhalation: Low acute inhalation toxicity. May cause upper respiratory tract irritation. Acute Ingestion: Low acute oral toxicity.
