SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

/GUIDE 151: SUBSTANCES - TOXIC (NON-COMBUSTIBLE)/ Health: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. 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. /Organophosphorus compound, poisonous, liquid, NOS; Organophosphorus compound, toxic, liquid, NOS; Organophosphorus compound, poisonous, NOS; Organophosphorus compound, toxic, NOS (Triisopropyl phosphite)/|/GUIDE 151: SUBSTANCES - TOXIC (NON-COMBUSTIBLE)/ Fire or Explosion: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated.

As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at lease 25 meters (75 feet) for solids. Keep unauthorized personnel away. Stay upwind.

phosphorous acid, triisopropyl ester

All other basic organic chemical manufacturing|Phosphorous acid, tris(1-methylethyl) ester: ACTIVE|On December 29, 2004, the Department of Commerce Bureau of Industry and Security announced the implementation of the Understandings Reached at the June 2004 Australia Group (AG). Among several items, this rule adds the following four precursor chemicals to the list of chemicals in Export Control Classification Number (ECCN) 1C350.d that may be used as precursors to toxic chemical agents: Tri-isopropyl phosphite; O,O-diethyl phosphorothioate; O,O-diethyl phosphorodithioate; and Sodium hexafluorosilicate.

A flame ionization detector was modified so hydrogen flame could also be used as emission source for flame photometric detector.
