Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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 protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep away from combustible materials. Avoid contact unless wearing appropriate protective clothing. Stop leak if you can do it without risk. With clean shovel place material into clean, dry container and cover loosely; move containers from spill area.
Stability
Normally stable, reactive under extreme conditions.
Incompatibilities
May react explosively.

Fire.
Fire fighting
Fire fighting phases: use water spray. Wear self-contained breathing apparatus due to decomposition above 165 degrees fahrenheit, with release of toxic gaseous oxides of nitrogen.
Fire potential
Nonflammable.
Hazards
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Combustion products
Toxic oxides of nitrogen may form in fire.

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 result in injury, burns and death.
   Eyes
See Skin.

First aid
 
   Ingestion
Give large amount of water; induce vomiting; call a doctor.
   Inhalation
Move to fresh air; if breathing has stopped, begin artificial respiration and call a doctor.
   Skin
Flush with water.
   Eyes
Flush with water for at least 15 min.
