4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
In case of skin contact
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowed
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
It 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 necessary
A 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 media
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped or safely confined. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, carbon dioxide or dry chemical. /Organophosphorus pesticides, liquid, NOS/
5.2 Specific hazards arising from the chemical

12.2 Persistence and degradability
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 potential
Based 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 soil
After 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 effects
no data available
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. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
