First Aid Measures

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.; consult a physician if irritation persists.

Handling and Storage

Storage
Cool, dry location. Tightly sealed container.
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.

Hazards Identification

Inhalation
An interstitial fibrotic pulmonary process has been described among hard metal workers and diamond polishers.
Ingestion
Ingestion or inhalation of cobalt causes nausea, vomiting, diarrhea, and colicky abdominal pain.
Hazards
Toxic cobalt oxide fumes may form in fire.

Exposure Controls/Personal Protection

Personal Protection
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
NIOSH approved respirator with dust/mist filter.
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.
Exposure limit(s)
OSHA PEL: 0.1 mg/m3 as Co.

Fire Fighting Measures

Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Accidental Release Measures

Small spills/leaks
Sweep up and place in a suitable clean, dry containers for reclamation or disposal. Keep unnecessary people away.

Stability and Reactivity

Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
When heated to decomposition, emits toxic fumes of sulfur oxides.
