SECTION 2: Hazards identification

OSHA EMERGENCY OVERVIEW Metallic wire, rod or strip Odorless Flash Point: Not Applicable Danger Contains CADMIUM AND (IN CASE OF 50N) NICKEL. Avoid creating dust. SUSPECT CANCER HAZARD - Risk of cancer depends on route, duration and level of exposure. Harmful if inhaled or swallowed. May cause eye and skin irritation. Prolonged or repeated contact may result in argyria (discoloration) of the eyes, skin, respiratory tract or other mucous membranes. Prolonged or repeated exposure may cause liver and kidney damage. Not a fire or explosion hazard in solid form. Finely divided dust may ignite and burn rapidly when mixed with air in the proper proportions. Toxic metal fumes may be released in a fire situation. ROUTES OF ENTRY Eyes? YES Skin? YES Inhalation? YES Ingestion? YES

Potential health effects

EYE CONTACT may cause irritation. SKIN CONTACT may cause irritation. INHALATION may cause excessive CADMIUM absorption resulting in pulmonary emphysema and/ or kidney dysfunction. INGESTION is harmful. May cause abdominal pain, nausea, vomiting and diarrhea. COPPER poisoning can result in hemolytic anemia and kidney, liver and spleen damage. NOTE: Inhalation of fumes may cause a flu-like illness called metal fume fever. Typically metal fume fever begins four to twelve hours after sufficient exposure to freshly formed fumes. The first symptoms are a metallic taste, dryness and irritation of the throat. Cough and shortness of breath may occur along with headache, fatigue, nausea, vomiting, muscle and joint pain, fever and chills. The syndrome runs its course in 24-48 hours. NOTE: The potential health effects described above only apply if dust or fume is formed. CARCINOGENICITY NTP? YES IARC? YES OSHA? YES In evaluating CADMIUM and CADMIUM COMPOUNDS, the International Agency for Research on Cancer (IARC) has determined that there is sufficient evidence of carcinogenicity to humans (Group 1). SIMILAR CARCINOGENICITY RESULTS FOR NICKEL. The Occupational Safety and Health Administration (OSHA) and the American Conference of Governmental Industrial Hygienists (ACGHIG) considers all cadmium and cadmium compounds to be suspect human cancer hazard (A2). The National Toxicology Program (NTP) lists only cadmium and certain cadmium compounds as substances which may reasonably be anticipated to be carcinogenic. This product contains one of those cadmium compounds specifically identified by NTP.

Health hazards

Refer to Potential Health Effects and Carcinogenicity. Prolonged or excessive exposures may result in argyria, a permanent localized blue-grey discoloration of the eyes, skin or mucous membranes. Repeated or long-term exposure to CADMIUM or NICKEL, even at relatively low concentrations, may result in kidney damage and an increased risk of lung cancer.

Medical Conditions Generally Aggravated by Exposure

May aggravate existing medical conditions, such as respiratory and/or kidney ailments. Individuals with Wilson’s Disease are at increased risk of COPPER poisoning. NOTE: See Section 8 for Exposure Limits Section 11 for Toxicological Information and Section 12 for Ecological Information.
