Azinphos methyl is a colorless brown, waxy or white crystalline solid dissolved in a liquid carrier. It is used as a pesticide. It is added to water to create a water emulsifiable liquid. It is toxic by inhalation, skin absorption, and/or ingestion. It is heavier than and insoluble in water. In case of damage to, leaking from containers of this material contact CHEMTREC, 800-424-9300.

Decomposes above 200°C . Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides, phosphorus oxides and sulfur oxides.
Solutions in ethanol and propylene glycol are stable for at least 3 weeks.
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. Azinphos Ethyl may behave similarly. At elevated temperatures, it will decompose generating toxic gases.

The substance may cause effects on the nervous system. This may result in convulsions and respiratory failure. Cholinesterase inhibition. Exposure could cause unconsciousness and death. The effects may be delayed. Medical observation is indicated.
Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
AEROBIC: Azinphosmethyl was degraded in batch and continuous culture by mixed enrichment cultures of microorganisms that were collected from soil, raw sewage, a trickling filter, activated sludge, and settled sludge(1). Azinphosmethyl concentration decreased from 99 mg/L to 49 mg/L after 4 days incubation in a stirred flask containing azinphosmethyl as the sole carbon source and a mixed culture(1). The main degradation products of azinphosmethyl in soil and by selected soil microorganisms are benzazimide, thiomethylbenzazimide, bis-(benzazimidyl-methyl) disulfide, and anthranilic acid(2). Using analytical grade and diluted emulsifiable concentrated azinphosmethyl, at a concentration of 15 ppm, incubated at 30 deg C in Carrington silt loam degradation was 95% in 6 and 22 days, respectively(3). After 10 weeks, no residual azinphosmethyl was detected(3). The half-life of azinphosmethyl in seawater (pH 8.1) was 26 days when incubated in the absence of light, while the half-life in river water (pH 7.3) was 42 days, 35 days (pH 7.3) in filtered river water when incubated in closed 2.5 Liter amber bottles at 22 deg C(4).
An estimated BCF of 30 was calculated in fish for azinphosmethyl(SRC), using a log Kow of 2.75(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
The Koc of azinphosmethyl in five European soils was measured in the range of 487 to 4,644(1). Azinphosmethyl also had Koc values of 1990 (75.0% clay, 3.29% organic carbon), 783 (22.6% clay, 2.39% organic carbon), 570 (17.0% clay, 3.32% organic carbon), 630 (20.3% clay, 1.36% organic carbon) and 1700 (6.0% clay, 4.43% organic carbon) in five European soils(2). Using data from the 1993 UK database, Koc values for azinphosmethyl were 298 to 3406(3). According to a classification scheme(4), this Koc data suggests that azinphosmethyl is expected to have moderate to slight mobility in soil. Measurable residues were found in sediment samples after application to the surface of littoral enclosure mesocosms; the sediment and water were identified as the most important sorptive compartments(5). The compound is not likely to leach to groundwater except in areas of high recharge such as karst(6).

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.
