Indication of any immediate medical attention and special treatment needed
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Aggressive airway control may be needed. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Organophosphates and related compounds
Extinguishing media
Use foam, powder, carbon dioxide.
Specific Hazards Arising from the Chemical
Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.
Advice for firefighters
Use foam, powder, carbon dioxide.

Persistence and degradability
AEROBIC: The half-life of demeton-S-methyl in soil was reported as 26 days(1), suggesting that demeton-S may be susceptible to biodegradation in soil(SRC).
Bioaccumulative potential
An estimated BCF of 8 was calculated in fish for demeton-S(SRC), using a water solubility of 2,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc value for demeton-S was reported as 70 in an unspecified soil(1). According to a classification scheme(2), this Koc value suggests that demeton-S is expected to have high mobility in soil(SRC).
Other adverse effects
no data available
Disposal methods
ProductThe 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.
