maneb usage and synthesis

usage	maneb is a complex of manganese with the ethylene bis(dithiocarbamate) anionic ligand. maneb is a foliate fungicide used to protect crops in agriculture. maneb is also useful in creating a toxin-based animal (usually primates) model of parkinson's disease.
general description	maneb is a yellow powder or crystalline solid. maneb is denser than water. contact may irritate skin, eyes and mucous membranes. maneb may be toxic by ingestion. likely to generate heat spontaneously upon exposure to air or water. may be sufficient to ignite the material. maneb is used as a fungicide. formulations of maneb include mixing maneb with many other chemicals such as sulfur, zinc oxide and others to desensitize it. this is done to make maneb easer for application.
air & water reactions	highly flammable. soluble in water. maneb is likely to generate heat spontaneously, especially when wet. the heat may be sufficient to ignite the material. thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. such decompositions are accelerated by acids.
reactivity profile	the bps pesticide incident in helena resulted in an explosion and death of three firemen. the burning of a 1,000 pound sack of azinphos methyl or the flashing of maneb which was present on the facility may have caused the explosion.
health hazard	fire will produce irritating, corrosive and/or toxic gases. inhalation of decomposition products may cause severe injury or death. contact with substance may cause severe burns to skin and eyes. runoff from fire control may cause pollution.
fire hazard	flammable/combustible material. may ignite on contact with moist air or moisture. may burn rapidly with flare-burning effect. some react vigorously or explosively on contact with water. some may decompose explosively when heated or involved in a fire. may re-ignite after fire is extinguished. runoff may create fire or explosion hazard. containers may explode when heated.
