Nature of Hazard II
CO has an affinity for the oxygen binding site in the blood; 200 times more so than oxygen
Other Potential Hazards (Atypical): highly flammable, may form explosive mixtures when mixed in air, may react to finely dispersed metal powders to form toxic and flammable carbonyls, may react vigorously w/ oxygen, acetylene, chlorine, fluorine, nitrous oxide.
Other Physical Properties: BP -191ºC, MP -205°C, Explosive Limits (volume % in air) 12.5-74.2
