10. STABILITY AND REACTIVITY
10.1 Reactivity
Stable at a normal temperature and pressure
10.2 Chemical stability
No data available.
10.3 Possibility of hazardous reactions
No dangerous reactions known.
10.4 Conditions to avoid
Avoid a contact with heat, flame, spark and other sources of ignition.
Vapor has a explosiveness.
Do not contact with a skin.
May cause frostbite.
Because of a pressure, containers may be burst if exposed to heat, and
thus could move to a long distance.
10.5 Incompatible materials
Strong oxidizer : Hazard of fire, explosion
Nitric acid, chlorine dioxide : Material to be avoided
Carbonyl nickel & acid: Explode at (20~40) ℃
10.6 Hazardous decomposition products
Pyrolysis product may contain poisonous carbon oxidized substance
