Hazards and Protection.
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.
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.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
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.
Normally stable, reactive under extreme conditions.
May react explosively.
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.
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Toxic oxides of nitrogen may form in fire.
IDHL: 20 mg/m3
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 or inhalation of cobalt causes nausea, vomiting, diarrhea, and colicky abdominal pain.
An interstitial fibrotic pulmonary process has been described among hard metal workers and diamond polishers.
Contact may result in injury, burns and death.
Give large amount of water; induce vomiting; call a doctor.
Move to fresh air; if breathing has stopped, begin artificial respiration and call a doctor.
Flush with water.
Flush with water for at least 15 min.
