3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: A shiny metallic foil. As shipped, the primary hazard is the
sharp edges of the product. Some individuals may develop allergic skin reactions after
repeated handling. If melted in a fire, toxic fumes may be released.
POTENTIAL HEALTH HAZARDS
SKIN: Handling of sharp edges may cause cuts. Repeated contact may cause allergic skin reaction
resulting in irritation or dermatitis.
EYES: Not a normal route of entry. Solid particles generated by grinding and sanding may cause
irritation.

INHALATION: Vapors and fumes resulting from the grinding, sanding, cutting and/or welding of this
material are harmful if inhaled. Symptoms may include irritation of throat and respiratory
tract. Exposures may result in 鈥渕etal fume fever鈥? which can produce flu-like symptoms.
INGESTION: Not a route of entry.
DELAYED EFFECTS: Repeated inhalation of vapors and fumes may result in toxic effects to the lungs.
Cobalt and cobalt compounds and nickel and nickel compounds have caused cancer
in laboratory animals and should be treated as 鈥榩ossible鈥? carcinogens. At present
there is no reliable evidence that cobalt or nickel metal has caused cancer in humans.
Long term nickel exposure may affect kidney function.
Although hexavalent chrome is considered a potential carcinogen, the trivalent
(metallic) chrome in this product is not considered to be a carcinogen.
