Fire HazardsNot combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances.

Hazards Summary · 1 item

Causes somnolence, diarrhea, and weight loss in oral lethal-dose studies of rats; [RTECS] A fire hazard on contact with combustible materials; A skin, eye, and respiratory tract irritant; May cause skin sensitization and asthma; May have effects on the heart, thyroid, and bone marrow (cardiomyopathy, goiter, and polycythemia); Possibly toxic to reproduction and teratogenic, based on animal studies; [ICSC] An oxidizing agent that may intensify fire; An irritant; May cause skin and respiratory sensitization; [Alfa Aesar MSDS] See Cobalt. See NITRATES and NITRITES.

Chemical DangersDecomposes on heating. This produces toxic gases including nitrogen oxides. Reacts with combustible substances. This generates fire hazard.

Exposure Control and Personal ProtectionBiological Exposure Indices (BEI) [ACGIH] - Cobalt in urine = 15 ug/L; sample at end of shift at end of workweek;

Spillage Disposal · 1 item

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.

Eye PreventionWear safety goggles or eye protection in combination with breathing protection if powder.
