Do NOT use Water. Use dry chemical, CO2. Wear a self contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.
When heated to decomposition, may emit toxic fumes of iodine.
OSHA/PEL: 0.1 mg/m3 (as Co) (0.1 ppm I2)
Co compounds: Experimental evidence shows that the toxicity of cobalt by mouth is low. In animals, administration of cobalt salts produces polycythemia. May cause kidney and liver damage in humans. Locally, cobalt has been shown to produce dermatitis. There have also been reports of hematologic, digestive, and pulmonary changes in humans. It is a suspected carcinogen of the connective tissue and lungs. Prolonged absorption of iodides may produce idoism which is manifested by skin rash, running nose, headache and irritation of the mucous membrane. In severe cases, the skin may show pimples, boils, redness, black and blue spots, hives and blisters. Weakness, anemia, loss of weight and general depression may occur.
May cause coughing, sneezing, difficulty breathing and irritation of mucous membrane of the respiratory tract.
May cause itching, irritation, inflammation and dermatitis.
May cause irritation, burning sensation, redness, and watering of the eyes if comes in contact with them. There may be risk of serious injury.
Give 1-2 glasses of milk or water. Induce vomiting, seek immediate medical attention.
Remove to fresh air. Administer oxygen if breathing is difficult. Seek medical attention.
Remove any contaminated clothing, brush material off of skin, flush with running water and soap. Seek medical attention.
