SECTION VI - HEALTH HAZARD DATA |
| 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) The inorganic bromides produce depression, emaciation, and, in severe cases, psychosis and mental deterioration. Bromide rashes (bromoderma) especially of the face and resembling acne and furninculosis, often occur when bromide inhalation or administration is prolonged. (Sax, Dangerous Properties of Industrial Materials, eighth edition) INHALATION: Acute: May cause shortness of breath, coughing, depression, emaciation, weight loss and pulmonary damage. Chronic: May cause diffuse nodular fibrosis, respiratory sensitivity, psychosis and mental deterioration. Prolonged inhalation may cause bromoderma. INGESTION: Acute: Moderately toxic by ingestion. May cause acute cobalt poisoning. Chronic: No chronic health effects recorded. SKIN: Acute: May cause irritation. Chronic: May cause allergic sensitization, dermatitis and bromoderma. EYE: Acute: May cause irritation and possibly damage the cornea. Chronic: No chronic health effects recorded. TARGET ORGANS: May affect the skin, respiratory and pulmonary system. . |

| CARCINOGENICITY: | NTP? No IARC Monographs? Yes OSHA Regulated? No |
| CARCINOGENICITY/OTHER INFORMATION | |
|
Cobalt: 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. |

|
No toxicity data recorded |
|
| SIGNS AND SYMPTOMS OF EXPOSURE | |
|
INHALATION: May cause shortness of breath, coughing, loss of weight, depression, emaciation. Bromoderma may cause a rash resembling acne and furinculosis. INGESTION: Acute cobalt poisoning may cause: diarrhea, lower blood pressure and body temperature. SKIN: May cause redness, itching and inflammation. Bromoderma may cause a rash resembling acne ad furinculosis. EYE: May cause redness, itching and watering. . |
|
| MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE | |
|
Pre-existing respiratory or skin disorders. |
|
| EMERGENCY AND FIRST AID PROCEDURES | |
|
INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention. INGESTION: Give 1-2 glasses of milk or water and induce vomiting; seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person. SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention. EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention. . |
