Reactivity
ZIRAM is a dithiocarbamate. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides. ZIRAM is corrosive to iron and copper. It is incompatible with strong oxidizing agents and acids. It is also incompatible with mercury. (NTP, 1992)
