EYES: Flush with water for at least 15 minutes. If irritation occurs and persists, contact
a medical doctor.
SKIN: Remove contaminated clothing and thoroughly wash with soap and water. If
irritation occurs and persists, contact a medical doctor.
INGESTION: Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do
not induce vomiting. Never give anything by mouth to an unconscious person. See a
medical doctor immediately.
INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and
persists, contact a medical doctor.
NOTES TO MEDICAL DOCTOR: This product has low oral, dermal and
inhalation toxicity. It is moderately irritating to the skin and eyes. Reversible skin
sensations (paresthesia) may occur and ordinary skin salves have been found useful in
reducing discomfort. Contains aromatic hydrocarbons that may produce a severe
pneumonitis if aspirated during vomiting. Consideration should be given to gastric
lavage with an endotracheal tube in place. Treatment is otherwise controlled removal of
exposure followed by symptomatic and supportive care.
5. FIRE FIGHTING MEASURES
FLASH POINT AND METHOD: 42°C (108°F) (CC)
EXTINGUISHING MEDIA: Foam, CO2 or dry chemical. Soft stream water fog
only if necessary. Contain all runoff.
FIRE / EXPLOSION HAZARDS: Moderately combustible. When heated above
the flash point, this material releases vapors which, when mixed with air, can burn or be
explosive.
FIRE FIGHTING PROCEDURES: Isolate fire area. Evacuate downwind. Wear
full protective clothing and self-contained breathing apparatus. Do not breathe smoke,
gases or vapors generated.
HAZARDOUS DECOMPOSITION PRODUCTS: Carbon monoxide and/or
carbon dioxide. Chlorine and hydrogen chloride may be formed.
6. ACCIDENTAL RELEASE MEASURES
http://msds.fmcweb.com/files/61334gdu.htm RELEASE NOTES: Isolate and post spill area. Wear protective clothing and
personal protective equipment as prescribed in Section 8, "Exposure Controls/Personal
Protection". Keep unprotected persons and animals out of the area.
Keep material out of lakes, streams, ponds and sewer drains. Dike to confine spill and absorb with a non-combustible absorbent such as clay, sand or soil. Vacuum, shovel or pump waste into a drum and label contents for disposal. To clean and neutralize spill area, tools and equipment, wash with a suitable solution (i.e., bleach or caustic/soda ash and either ethylene glycol or an appropriate alcohol, i.e., methanol, ethanol or isopropanol). Follow this by washing with a strong soap and water solution. Absorb as above, any excess liquid and add to the drums of waste already collected. Repeat if necessary. Dispose of drummed waste according to the method outlined in Section 13, "Disposal Considerations". 7. HANDLING AND STORAGE
GENERAL PROCEDURES: Store in a cool, dry, well-ventilated place. Do not use
or store near heat, open flame or hot surfaces. Store in original containers only. Keep out
of reach of children and animals. Do not contaminate other pesticides, fertilizers, water,
food or feed by storage or disposal.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS: Use local exhaust at all process locations where vapor or
mist may be emitted. Ventilate all transport vehicles prior to unloading.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: For splash, mist or spray exposure, wear chemical protective
goggles or a face shield.
RESPIRATORY: For splash, mist or spray exposure wear, as a minimum, a properly
fitted half-face or full-face air-purifying respirator which is approved for pesticides (U.S.
NIOSH/MSHA, EU CEN or comparable certification organization). Respirator use and
selection must be based on airborne concentrations.
PROTECTIVE CLOTHING: Depending upon concentrations encountered, wear
coveralls or long-sleeved uniform and head covering. For larger exposures as in the case
of spills, wear full body cover barrier suit, such as a PVC suit. Leather items - such as
shoes, belts and watchbands - that become contaminated should be removed and
destroyed. Launder all work clothing before reuse (separately from household laundry).
WORK HYGIENIC PRACTICES: Clean water should be available for washing
http://msds.fmcweb.com/files/61334gdu.htm in case of eye or skin contamination. Wash skin prior to eating, drinking or using tobacco. Shower at the end of the workday. GLOVES:Wear chemical protective gloves made of materials such as nitrile, neoprene or Viton® brand. Thoroughly wash the outside of gloves with soap and water prior to removal. Inspect regularly for leaks. COMMENTS: Personal protective recommendations for mixing or applying this product
are prescribed on the product label. Information stated above provides useful, additional

ACUTE EFFECTS FROM OVEREXPOSURE: This product has low oral,
dermal and inhalation toxicity. It is moderately irritating to the skin and eyes. Experience
to date indicates that contact with this product has rarely produced skin sensations such
as numbing, burning or tingling. These sensations are reversible and usually subside
within 12 hours. Large, toxic doses administered to laboratory animals have produced
symptoms such as diarrhea, salivation, tremors and intermittent convulsions.
Overexposure to animals, via inhalation, has also produced hyperactivity and
hypersensitivity. Inhalation of aromatic hydrocarbon vapors may cause dizziness,
disturbances in vision, drowsiness, respiratory irritation, and eye, skin and mucous
membrane irritation. Vomiting after ingestion of this product may cause aspiration of
aromatic hydrocarbons into the lungs which may result in fatal pulmonary edema.
CHRONIC EFFECTS FROM OVEREXPOSURE: No data available for the
formulation. In studies with laboratory animals, permethrin did not cause reproductive
toxicity or teratogenicity. Analysis of chronic feeding studies in both mice and rats with
permethrin resulted in the conclusion that permethrin's potential for induction of
oncogenicity in experimental animals is low and that the likelihood of oncogenic effects
in humans is nonexistent or extremely low. Long-term feeding studies in animals
resulted in increased liver and kidney weights, induction of the liver microsomal drug
metabolizing enzyme system and histopathological changes in the lungs and liver. An
overall absence of genotoxicity has been demonstrated in mutagenicity testing with
permethrin. Chronic exposure to aromatic hydrocarbons may cause headaches, dizziness,
loss of sensations or feelings (such as numbness), and liver and kidney damage.
Inhalation of xylene vapors at high doses has also resulted in an increased incidence of
malformations and decreases in fetal weight in laboratory animals. Damage from xylene
may be potentiated by alcohol. Under the conditions of 2-year inhalation studies,
conducted by the National Toxicology Program (NTP), there was clear evidence of
carcinogenic activity of ethylbenzene in male rats based on increased incidences of renal
tubule neoplasms. The incidences of testicular adenoma were also increased. There was
some evidence of carcinogenic activity in female rats based on increased incidences of
renal tubule adenomas. There was some evidence of carcinogenic activity in male mice
based on increased incidences of alveolar/bronchiolar neoplasm. There was some
evidence of carcinogenic activity in female mice based on increased incidences of
hepatocellular neoplasms. Studies conducted by the International Agency for Research
on Cancer (IARC) showed that there is inadequate evidence in humans for the
carcinogenicity of ethylbenzene and that there is sufficient evidence in experimental
animals; therefore, the overall evaluation shows that ethylbenzene is possibly
carcinogenic to humans (Group 2B).

Unless otherwise indicated, the data presented below are for the active ingredient. ENVIRONMENTAL DATA: Permethrin is stable at a wide range of pH values.
Permethrin has a moderate rate of degradation in soil and the half-life is related to the
soil type, microbial population, concentration in the soil and the aerobic condition of the
soil. Because of its high affinity for organic matter (Koc = 86,000), there is little
potential for movement in soil or entry into ground water. Permethrin has a Log Pow of
6.1, but because of the ease with which biological systems degrade the molecule, the
potential for bioconcentration and accumulation in the environment is low (BCF = 500).
ECOTOXICOLOGICAL INFORMATION: Permethrin is highly toxic to fish
(LC50 = 0.5 µg/L to 315 µg/L) and aquatic arthropods (LC50 = 0.02 µg/L to 7.6 µg/L).
Marine species are often more sensitive than the freshwater species. Bacteria, algae,
mollusks and amphibians are much more tolerant of permethrin than the fish and
arthropods. Care should be taken to avoid contamination of the aquatic environment.
Permethrin is slightly toxic to birds and oral LD50 values are greater than 3600 mg/kg.
Longer dietary studies showed that concentrations of up to 500 ppm in the diet had no
effect on bird reproduction.
13. DISPOSAL CONSIDERATIONS
DISPOSAL METHOD: Open dumping or burning of this material or its packaging
is prohibited. If spilled material cannot be disposed of by use according to label
instructions, an acceptable method of disposal is to incinerate in accordance with local,
state and national environmental laws, rules, standards and regulations. However,
because acceptable methods of disposal may vary by location and regulatory
requirements may change, the appropriate agencies should be contacted prior to disposal.
EMPTY CONTAINER: Non-returnable containers which held this material should
be cleaned, prior to disposal, by triple rinsing. Containers which held this material may
be cleaned by being triple-rinsed, and recycled, with the rinsate being incinerated. Do
not cut or weld metal containers. Vapors that form may create an explosion hazard.
