Most important symptoms/effects, acute and delayed
This material may be fatal if swallowed, inhaled, or absorbed through the skin. Repeated inhalation or skin contact may progressively increase susceptibility to poisoning. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Airway protection. Ensure that a clear airway exists. Intubate the patients and aspirate the secretions with a large-bore suction device if necessary. Administer oxygen by mechanically assisted pulmonary ventilation if respiration is depressed. Improve tissue oxygenation as much as possible before administering atropine, so as to minimize the risk of ventricular fibrillation. In severe poisonings, it may be necessary to support pulmonary ventilation mechanically for several days. Organophosphate pesticides
SECTION 5: Firefighting measures

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces highly flammable and toxic gases (phosphine see ICSC 0694). Reacts with oxidizing substances. This produces toxic fumes including phosphorous oxides.
Chemical stability
Stable for at least two years at room temperature.
Possibility of hazardous reactions
Moderate fire risk.Organothiophosphates, such as TERBUFOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. This compound decomposes in the presence of acids or bases (NTP, 1992).
Conditions to avoid
no data available
Incompatible materials
no data available
Hazardous decomposition products
This compound decomposes in the presence of acids or bases /and/... at temperatures over 120 deg C.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 Lepomis macrochirus (bluegill sunfish) 0.004 mg/l/96 hr /Conditions of bioassay not specified
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
Soils from two sites in MO planted with corn and treated at different times with terbufos and other pesticides were examined for microbial populations and efficacy of residual insecticide treatment on ten day old house crickets, Acheta domesticus. ... Soil bacteria counts correlated well ... with the biological persistence of the cricket bioassay. ... Actinomycetes dominated the relationships of various degradation bioassay curves.
Bioaccumulative potential
An estimated BCF of 560 was calculated for terbufos(SRC), using a log Kow of 4.48(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
Koc values ranging from 500 to 5000 have been reported for terbufos(1-4). According to a classification scheme(5), these Koc values suggest that terbufos is expected to have low to slight mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
