SECTION 2: Hazards identification

EMERGENCY OVERVIEW CAUTION! Non-regulated. Color Grey Form Solid Powder Odor Odorless May cause eye, skin, and respiratory tract irritation. May cause allergic respiratory reaction. May be harmful if inhaled. May cause allergic skin reaction. May be harmful if swallowed. May cause lung damage. May cause cancer. Contains material which may cause cancer. Dust or fumes may be a fire and explosion hazard when exposed to high temperature or ignition. Ground containers and equipment before transferring to avoid static sparks. Do not use water to extinguish fire. Irritating gases/fumes may be given off during burning or thermal decomposition.

Principle Routes of Exposure

Eye Contact, Skin Contact, Inhalation, Ingestion HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE Inhalation Hazards Acute Inhalation Hazards: Inhalation of nickel compounds may cause respiratory tract irritation, cough, pneumonitis and fever. Symptoms may also include headache, dizziness and difficult breathing. Inhalation may also cause asthma, pulmonary fibrosis (increase in interstitial fibrous tissue in the lungs) and pulmonary edema (fluid in the lungs). Inhalation of cobalt may cause respiratory tract irritation with coughing, sore throat, sneezing and inflammation of the mucous membranes. Sensitization reactions may occur in previously exposed individuals. Chronic Inhalation Hazards: Repeated or prolonged inhalation of nickel compounds may cause chronic hypertrophic rhinitis (inflammation of the mucous membrane lining of the nasal passages) and nasal sinusitis. Repeated or prolonged inhalation of trivalent chromium compounds may cause chronic respiratory effects. (1) Studies of workers chronically exposed to cobalt in the tungsten carbide manufacturing of hard metal revealed three typesof respiratory disease. (1) Airway obstruction may occur from simple irritation and appears to be related to an allergic response. It has been reported to occur at a level of 0.06 mg/m3 and is characterized by wheezing, cough and shortness of breath. This syndrome may not develop until 6 to 18 months of exposure. However, once sensitized, a worker may have a sensitization reaction when exposed to very small amounts of cobalt. (2) Interstitial pneumonitis which is characterized by a decrease in lung efficiency and (3) interstitial fibrosis with cough and shortness of breath. Pulmonary function is decreased and death may occur due to pulmonary hypertension. Refer to CARCINOGENICITY (Section 3) for additional information concerning nickel, cobalt and chromium compounds. Skin Hazards Acute Skin Hazards: Direct skin contact may cause irritation and sensitization reactions ("nickel itch"). Symptoms may include a burning sensation, itching, and hives which may be followed by ulcers which discharge and become crusted. The skin eruptions may be delayed up to 7 days. In chronic stages, pigmented and unpigmented areas of the skin may be formed. (2) Direct contact with cobalt may cause skin irritation and skin sensitization. Skin eruptions may occur in skin areas subjected to friction, such as elbows, ankles and the neck. Chronic Skin Hazards: Repeated or prolonged contact with nickel compounds may cause sensitization and dermatitis. Repeated or prolonged skin contact with cobalt may cause sensitization dermatitis. Eye Hazards Acute Eye Hazards: Direct eye contact may produce irritation with symptoms of redness, swelling and pain. Ingestion Hazards Acute Ingestion Hazards: Ingestion of cobalt may cause vomiting and diarrhea. Chronic Ingestion Hazards: None known. Carcinogenic Effects: NTP, IARC and ACGIH found that "there is sufficient evidence for the carcinogenicity of Chromium and Certain Chromium Compounds both in humans and experimental animals". The Chromium Compounds that are considered carcinogenic are hexavalent chromium compounds. This product contains a metallic, divalent or trivalent chromium compound. It is not specifically listed as a carcinogen by NTP, IARC or ACGIH. Carcinogenic Components: NTP: Nickel (Ni) (Regulated as Nickel and Certain Nickel Compounds) Classified as an NTP Anticipated Human Carcinogen - "Substances or groups of substances that may reasonably be anticipated to be carcinogens." Cobalt (Regulated as Cobalt and Cobalt Compounds) Not listed IARC: Nickel (Ni) (Regulated as Nickel and Certain Nickel Compounds) Classified as IARC Possible Human Carcinogen (Group 2B) - "The chemical or group of chemicals is possibly carcinogenic for humans." Cobalt (Regulated as Cobalt and Cobalt Compounds) Classified as IARC Possible Human Carcinogen (Group 2B) - "The chemical or group of chemicals is possibly carcinogenic for humans."

Medical Conditions Generally Aggravated by Exposure

Persons with pre-existing eye, skin or respiratory conditions may be more susceptible to the effects of this product.
