4.2 Most important symptoms/effects, acute and delayedIt displays cholinesterase inhibiting properties. Death results primarily from respiratory arrest stemming from failure of the respiratory center, paralysis of respiratory muscles and intense bronchoconstriction. (EPA, 1998)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryA comatose patient who is diaphoretic, has pinpoint pupils and the odor of an insecticide on clothing or breath, and is noted to have muscle fasciculations represents the classic presentation of organophosphate poisoning. ... Specific steps in management include the following. 1. Decontamination. ... 2 Airway. Establish an airway if necessary. ... 3. Respiratory Status. Respiratory distress, in fact, is commonly found in these patients from multiple causes. ... 4. Cardiac Monitoring. ... 5. Cholinesterase Level. ... 6. Pralidoxime. Pralidoxime is the treatment of choice for organophosphate poisoning and should be used for nearly all patients with clinically significant orgnophosphate poisoning, particularly whose patients with muscular fasciculations and weakness. ... 7. Atropine. Atropine is the physiologic antidote for organophosphate poisoning. A trial dose of atropine should be instituted on clinical ground when one suspects organophosphate intoxication. /Organophosphate poisoning/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaIf material on fire or involved in fire: Do not extinguish fire unless flow can be stopped or safely confined.

- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
A number of soil bacteria, Nocardia spp and Arthrobacter ssp, degraded the products of fensulfothion hydrolysis and oxidation: 4-methylmercaptophenol (MMP); 4-methylsulfinylphenol (MSP); and 4-methylsulfonylphenol (MSO2P). Nocardia calcerea hydroxylated the ring to form a substituted catechol. Meta cleavage between carbons 2 and 3 ensued to give 2-hydroxy-5-methylmercaptomuconic semialdehyde from MMP and the corresponding sulfinyl analog from MSP. MSO2P was hydroxylated to form 4-methylsulfonylcatechol. In this case ortho cleavage occurred, splitting the ring between atoms 1 and 2 to form 3-methylsulfonylmuconic acid.
12.3 Bioaccumulative potentialBased on a log Kow value of 2.23(1), the log BCF for fensulfothion can be estimated to be 1.46 from a recommended regression equation(2,SRC). Based on a water solubility of 1540 ppm at 25°C (1), the log BCF can be estimated to be 0.99 from a recommended regression equation(2,SRC).
12.4 Mobility in soilAfter application at normal pesticide application rates to a greenhouse soil (65% organic matter, typical of soil used for onion production in Ontario, Canada), fensulfothion exhibited no significant vertical movement over a 10 week treatment period using a variety of watering schedules(1). Fensulfothion applied to soil did not leach beyond a 15 cm depth and remained in the initial zone of application over a period of 150 days(2). A Koc of 300 was reported for fensulfothion(3). According to a classification scheme(4), this Koc value suggests that fensulfothion is expected to have moderate mobility in soil(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 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.
Contaminated packagingContainers 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.
