/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. Runoff may pollute waterways. /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)/ Public Safety: CALL Emergency Response Telephone Number ... . 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. Keep out of low areas. /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)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible. /Organophosphorus compound, poisonous, liquid, NOS; Organophosphorus compound, toxic, liquid, NOS; Organophosphorus compound, poisonous, NOS; Organophosphorus compound, toxic, NOS (Triisopropyl phosphite)/

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.
