Exposure limit(s)
OSHA: PEL (8 h TWA): 0.1 mg/m3.
Exposure effects
Prolonged or repeated contact may cause dermatitis.
   Ingestion
Ingestion or inhalation of cobalt causes nausea, vomiting, diarrhea, and colicky abdominal pain.
   Inhalation
High vapour concentrations are irritating to the eyes and the respiratory tract may cause headache and dizziness, and are anaesthetic and may have other central nervous system effects.
   Skin
May cause irritation and de-fatting of skin.
   Eyes
The concentrated product is liable to cause redness and pain.

First aid
 
   Ingestion
Rise mouth. DO NOT INDUCE VOMITING. Give a glass of water to drink and transport to hospital. If unwanted vomiting occurs ensure patients' posture does not cause inhalation of liquid. Give more water to wash down throat and gullet. Never give anything by mouth to an unconscious person. Place in a coma position and maintain respiration.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
