Hazards and Protection.
Storage
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate chemical protective gloves, boots and goggles. For temporary operations which produce dust or fume or when ventilation is not practicable, an air-line respirator should be worn. If ventilation is not satisfactory, dust and/or fume respirator can be used. The maintenance worker should wear protective clothing, personal protection equipment, including eye protection, and suitable respiratory protective equipment.
Respirators
Any self contained breathing apparatus with a full facepiece and operated in a pressure demand or other positive pressure mode or any supplied air respirator with a full facepiece and operated in a pressure demand or other positive pressure mode in combination with an auxiliary self contained breathing apparatus operated in pressure demand or other positive pressure mode.
Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Add calcium hypochlorite (Ca(ClO)2). Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Stability
No data.
Incompatibilities
Reacts as bases to neutralize acids.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Fire potential
Material itself does not burn or burns with difficulty.
Hazards
Containers may explode when heated.
Combustion products
Toxic oxides of nitrogen may form in fire.

Health.
Exposure limit(s)
NIOSH REL: TWA 0.05 mg/m3 (as Co) OSHA PEL: TWA 0.1 mg/m3 (as Co) 20 mg/m3 (as Co)
Exposure effects
Administration of cobalt chloride to pregnant rats in doses up to 100 mg/kg/day did not produce teratogenicity or fetotoxicity. <br>CASE REPORT - A 31-year-old woman with severe cobalt-induced pulmonary fibrosis delivered a normal full term infant. Throughout the pregnancy, supplemental oxygen was required during exercise due to deterioration of respiratory capacity. Inhalation exposureor respiratory disease is present.
   Ingestion
Ingestion or inhalation of cobalt causes nausea, vomiting, diarrhea, and colicky abdominal pain.
   Inhalation
An interstitial fibrotic pulmonary process has been described among hard metal workers and diamond polishers.
   Skin
Contact may cause burns.
   Eyes
See Skin.

First aid
 
   Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   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
Flush with water for at least 15 minutes.
