5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Wear positive pressure breathing apparatus and special protective clothing. Remove and isolate contaminated clothing at the site. Move container from fire area if you can do so without risk. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material. (Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Small fires: dry chemical, carbon dioxide, water spray, or foam. Large fires: water spray, fog or foam. (EPA, 1998)
5.2 Specific hazards arising from the chemical
Shock can shatter container, releasing contents. (Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Runoff from fire control or dilution water may cause pollution. When heated to decomposition, it emits highly toxic fumes of oxides of nitrogen, phosphorus, and sulfur. Avoid alkali materials and heat. It is unstable to iron or tin surfaces and when mixed with certain carriers. (EPA, 1998)

No biodegradation was observed when dioxathion was anaerobically incubated for 25 hr with a bovine rumen inoculum(1). No aerobic biodegradability studies were located.
12.3 Bioaccumulative potential
The log octanol/water partition coefficient for dioxathion is estimated to be 2.99(1) from which one estimates a BCF of 110 using a recommended regression equation(2). Therefore dioxathion might be expected to bioconcentrate moderately in fish and aquatic organisms.
12.4 Mobility in soil
The log octanol/water partition coefficient for dioxathion is estimated to be 2.99(1) from which one estimates a Koc of 1000 using a recommended regression equation(2), indicating moderately strong adsorptivity to soil.

13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
