Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
The systemic effects of this compound are similar to parathion. It is an extremely potent systemic toxicant via ingestion, inhalation and skin contact. It may cause death or permanent injury after very short exposure to small quantities. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Atropine and enzyme-reactivating agents counteract the effects of azinphos-ethyl.

SECTION 10: Stability and reactivity
Reactivity
Nearly insoluble in water. What little amount is solubilized will readily hydrolyze.
Chemical stability
Thermo-stable ... readily hydrolyzed by alkali.
Possibility of hazardous reactions
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.
Conditions to avoid
no data available
Incompatible materials
Contact with oxidizers may cause the release of phosphorous oxides. Contact with strong reducing agents, such as hydrides, may cause the formation of flammable and toxic phosphine gas.
Hazardous decomposition products
When heated to decomposition it emits very toxic fumes of /phosphorous oxides, sulfur oxides, and nitrogen oxides/.

Persistence and degradability
AEROBIC: The methyl analogue, azinphos methyl, biodegraded in laboratory tests and in soil(1,2) which suggests that azinphos ethyl would also be degraded in the environment(SRC). The half-life of azinphos ethyl in seawater (pH 8.1), river water (pH 7.3) and filtered river water (pH 7.3) was 58, 65 and 36 days, respectively when incubated in the absence of light, in closed 2.5 Liter amber bottles at 22 deg C(3).
Bioaccumulative potential
An estimated BCF of 80 was calculated in fish for azinphos ethyl(SRC), using a log Kow of 3.40(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).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of azinphos ethyl can be estimated to be 170(SRC). According to a classification scheme(2), this estimated Koc value suggests that azinphos ethyl is expected to have moderate mobility in soil. Using a lysimeter to measure the leachability of various pesticides, azinphos ethyl was not detected in leachate from 3,000 individual analyses conducted from 1977-1986 (detection limit 0.001 mg/L)(3). These tests were conducted using 1-1.3 m in height by 0.5 sq m of top soil with a catch base of 1 sq m(3). For soil material, loamy or silty sand with a low humus content was used where the sum of clay and silt amounted to a maximum of 30% (clay below 10%) and the content of organic bound carbon did not exceed 1.5%(3).
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.
