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.
