metham sodium usage and synthesis

general description	a yellow to light yellow-green aqueous solution with an odor of amine and sulfur that varies in intensity. boiling point 230°f. metham sodium has a specific gravity of 1.162. metham sodium will decompose upon dilution to carbon disulfide, monomethylamine, methylisothiocyanate, and hydrogen sulfide. the decomposition products are flammable and toxic. the acute symptoms of exposure to metam sodium are excessive salivation, sweating, fatigue, weakness, nausea, headache, dizziness, eye and respiratory tract irritation, and skin irritation in the form of rashes. the spillage of a rail car tanker of metal sodium into the sacramento river caused a major fish kill (over a million trout) along several miles of that river.
air & water reactions	slow reaction upon dilution produces toxic gases hydrogen sulfide and methylisothiocyanate. this reaction is accelerated by the addition of acid.
reactivity profile	metam sodium 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.
health hazard	toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard	non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). contact with metals may evolve flammable hydrogen gas. containers may explode when heated.
