| Hazard Information | Back Directory | [Uses]
Fensulfothion is a highly toxic insecticide used for agriculture purposes. | [Uses]
Nematocide, insecticide. | [General Description]
Oily yellow or brown liquid. Used as an insecticide, nematocide and mosquito larvicide. | [Air & Water Reactions]
Incompatible with alkali chemicals. Hydrolyzes in alkali, isomerize in air [EPA, 1998]. Slightly soluble in water. | [Reactivity Profile]
Organothiophosphates, such as FENSULFOTHION, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. | [Health Hazard]
FENSULFOTHION displays cholinesterase inhibiting properties. Death results primarily from respiratory arrest stemming from failure of the respiratory center, paralysis of respiratory muscles and intense bronchoconstriction. | [Fire Hazard]
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) FENSULFOTHION may burn but may not ignite readily. Containers may explode in heat of fire. When heated highly toxic fumes of phosphorus and sulfur oxides are emitted. Incompatible with alkali chemicals. Hydrolyzes in alkali, isomerizes in air. | [Hazard]
Cholinesterase inhibitor. Questionable carcinogen. | [Potential Exposure]
A potential danger to those involved
in the manufacture, formulation, or application of this
insecticide used to control parasitic, sedentary, and freeliving nematodes. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts
the skin, remove contaminated clothing and wash immediately with soap and water. Speed in removing material
from skin is of extreme importance. Shampoo hair
promptly if contaminated. Seek medical attention immediately. If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has
stopped and CPR if heart action has stopped. Transfer
promptly to a medical facility. When this chemical has
been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Keep victim quiet and maintain
normal body temperature. Effects may be delayed; keep
victim under observation | [Shipping]
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1;
Labels: 6.1-Poisonous materials, Technical Name Required | [Incompatibilities]
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Strong oxidizers may cause
release of toxic phosphorus oxides. Organophosphates, in the
presence of strong reducing agents such as hydrides, may
form highly toxic and flammable phosphine gas. Keep away
from alkaline materials. | [Description]
Fensulfothion is a systemic
previously but not currently registered for insecticidal
and nematicidal activity in the United States. | [Chemical Properties]
Fensulfothion is a yellow oil. | [Chemical Properties]
Liquid. | [Waste Disposal]
Alkaline hydrolysis. In
accordance with 40CFR165, follow recommendations for
the disposal of pesticides and pesticide containers. Must be
disposed properly by following package label directions or
by contacting your local or federal environmental control
agency, or by contacting your regional EPA office. | [Definition]
ChEBI: Fensulfothion is an organic thiophosphate, a sulfoxide and an organothiophosphate insecticide. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an agrochemical, an avicide and a nematicide. It is functionally related to a 4-(methylsulfinyl)phenol. | [Environmental Fate]
Soil. In soils, the bacterium Klebsiella pneumoniae degraded fensulfothion to fensulfothion sul?de (Timms and MacRae, 1982, 1983). The following microorganisms were also capable of degrading the parent compound to the corresponding sul?de: Escherichia coli, Pseudomonas ?uorescens, Nocardia opaca, Lactobacillus plantarum and Leuconostoc mesenteroides (Timms and MacRae, 1983).
Plant. Readily oxidized in plants to the corresponding sulfone (Hartley and Kidd, 1987).
Chemical/Physical. Emits toxic fumes of phosphorus and sulfur oxides when heated to decomposition (Sax and Lewis, 1987; Lewis, 1990).
Isomerizes readily to the O,S-diethyl isomer (Worthing and Hance, 1991). The hydrolysis half-lives of fensulfothion in a sterile 1% ethanol/water solution at 25°C and pH values of 4.5, 6.0, 7.0 and 8.0, were 69, 77, 87 and 58 weeks, respectively (Chapman and Cole, 1982).
| [storage]
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handlingand storage. Store in tightly closed containers in a cool,well-ventilated area away from strong bases; strong oxidizers. Where possible, automatically pump liquid fromdrums or other storage containers to process containers. |
