SECTION 5 : Health Hazards

2 Cobalt oxide: Route of Exposure: Inhalation? Yes , Skin? Yes , Eyes? Yes , Ingestion? Yes , Other: N Potential Health Effects: Eye Contact: May cause irritation. Skin Contact: May cause irritation. Inhalation: May cause irritation to the upper respiratory tract. Ingestion: Poison by ingestion. May cause acute cobalt poisoning. Chronic Eye Contact:a No chronic health effects recorded. Chronic Skin Contact: May cause allergic sensitization and dermatitis. Chronic Inhalation: May cause permanent respirator disease, occupational asthma and interstitual fibrosis. Chronic Ingestion: No chronic health effects recorded. Carcinogenicity: NTP? Yes , IARC Monographs? Yes , OSHA Regulated? Yes Target Organs: May affect the respiratory and skin. . Signs/Symptoms: INHALATION: May cause shortness of breath, coughing, wheezing, chest tightness and loss of weight. INGESTION: Acute cobalt poisoning may cause: nausea, vomiting, headaches, dizziness, diarrhea, lower blood pressure and body temperature. SKIN: May cause redness, itching and inflammation. EYE: May cause redness, itching and watering. . Other Potential Health Effects: CARCINOGENICITY/OTHER INFORMATION: IARC 2B: Possibly Carcinogenic to Humans. The exposure circumstances entails exposures that are possibly carciongenic to humans. This category is used for agents, mixtures, and exposure circumstances for which there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals. It may also be used when there is inadequate evidence of cacinogencity in humans but there is sufficient evidence of carciongenecity in experimental animals. In some instances, an agent, mixture, or exposure circumstance for which theres is inadequate evidence of carcinogenicity in humans but limited evidence of carciongencity in expierimental animals together with supporting evidence from other relevant data may be placed in the group. ACGIH−TLV A3: Confirmed Animal Carcinogen with unknown relevance to humans: The agent is carcinogenic in experimental animals at a relatively high dose, by route(s) of administration, at site(s), of histologic type(s), or by mechanism(s) that may not be relevant to worker exposure. Available epidemiologic studies do not confirm an increased risk of cancer in exposed humans. Available evidence does not suggest that the agent is likely to cause cancer in humans except under uncommon or unlikely routes or levels of exposure.

Aggravation of Pre−Existing Conditions: Pre−existing respiratory or skin disorders. See "Section II" LD 50/LC 50: See "Other Toxicity Data"

SECTION 6 : Emergency And First Aid Procedures Physical Health Hazard: HEALTH HAZARDS (ACUTE AND CHRONIC): Cobalt has a low toxicity by ingestion. Ingestion of soluble salts, produces nausea and vomiting by local irritation. In animals, administration of cobalt salts produces an increase in the total red cell mass of the blood. In humans, a single case of poisoning with liver and kidney damage has been attributed to cobalt. Locally, cobalt has been shown to produce dermatitis and investigators have been able to demonstrate a hypersensitivity of the skin to cobalt. There have been reports of hematologic, digestive and pulmonary changes in humans. (Sax, Dangerous Properties of Industrial Materials, eighth edition)

3 Eye Contact: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
