V. HEALTH HAZARD INFORMATION
Effects of Exposure:
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 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.
Acute Effects:
Inhalation: May cause shortness of breath, coughing, weight loss and pulmonary damage.
Ingestion: Moderately toxic by ingestion. May cause acute cobalt poisoning.
Skin: May cause irritation.
Eye: May cause irritation and possibly damage the cornea.
Chronic Effects:
Inhalation: May cause diffuse nodular fibrosis and respiratory sensitivity.
Ingestion: No chronic health effects recorded.
Skin: May cause allergic sensitization and dermatitis.
Eye: No chronic health effects recorded.
Primary Routes of exposure: Inhalation, ingestion, skin or eye contact.
Target Organs: May affect the respiratory and pulmonary system.
Carcinogenicity: NTP: No IARC: No OSHA: No
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.

IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a tightly sealed container, in a cool, dry, well-ventilated area. Wash thoroughly after handling. Avoid contact with skin and eyes. Avoid breathing dust. Use only with adequate ventilation.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air.
