Fire HazardsNot combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Hazards SummaryA skin, eye, and respiratory tract irritant; May cause skin sensitization; [ICSC] Harmful if swallowed; May cause skin and respiratory tract sensitization; [MSDSonline] See Cobalt.

Chemical DangersDecomposes on heating. This produces irritating fumes. Reacts with strong oxidants. This generates fire and explosion hazard.

Packaging and LabellingDo not transport with food and feedstuffs.

Safety & protection

Fire FightingIn case of fire in the surroundings, use appropriate extinguishing media.

First Aid Measures · 4 items

Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

Safe StorageSeparated from strong oxidants. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
