SECTION 10: Stability and reactivity
Reactivity
20 mg/cu m (as Co). Cobalt metal dust and fume (as Co)
The substance , when finely divided, may ignite spontaneously on contact with air and acetylene. Reacts with strong oxidants. This generates fire and explosion hazard.
Chemical stability
Stable in air or toward water at ordinary temp.
Possibility of hazardous reactions
Only certain forms of cobalt metal are pyrophoric. ... Pyrophoric cobalt is a black powder that burns brilliantly when in contact with oxygen or air.Dust explosion possible if in powder or granular form, mixed with air.Pyrophoric COBALT is a reducing agent. Decomposes acetylene in the cold as the metal becomes incandescent [Mellor 14:513(1946-1947]. Incompatible with oxidizing agents such as ammonium nitrate, bromine pentafluoride, and nitryl fluoride.
Conditions to avoid
no data available

Other Information
Depending on the degree of exposure, periodic medical examination is suggested.The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation are therefore essential.Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.Do NOT take working clothes home.
