Emergency overview: Thermal decomposition and burning may form toxic
by-products. Highly toxic to fish and aquatic organisms. Keep out of drains and watercourses. Potential health effects: Effects from overexposure result from inhalation or
coming into contact with the skin. Contact with this product rarely produces skin sensations such as numbing, burning and tingling. These skin sensations are reversible and usually subside within 12 hours. Medical conditions aggravated by exposure: Skin affections.

Eyes: Flush with water for at least 15 minutes. If irritation occurs and persists,
obtain medical attention. Skin: Wash with plenty of soap and water.
Ingestion: : Drink one or two glasses of water and induce vomiting by
touching the back of the throat with a finger or by giving syrup of ipecac. Never induce vomiting or give anything by mouth to an unconscious person. Contact a medical doctor. Inhalation: Remove to fresh air. If breathing difficulty or discomfort occurs
and persists, obtain medical attention. Note to physician: Permethrin has low oral, dermal and inhalation toxicity,
and is minimally irritating to the eyes and practically non- irritating, to the skin. Reversible skin sensation (paresthesia) may occur and ordinary skin salves has been found useful in reducing discomfort. Treatment is otherwise controlled removal of exposure followed by symptomatic-and supportive care. 5. FIRE-FIGHTING MEASURES
Flash point: Not applicable.
Extinguishing media: Foam or water.
Explosion hazard: Not explosive.
Protective equipment: Wear full protective clothing and self-contained
breathing apparatus. Hazardous decomposition products: Carbon monoxide and carbon dioxide.
Minor quantities of chlorine and hydrogen chloride may be formed. More information: Isolate fire area. Evacuate downwind. Do not breathe
smoke gases generated. Page 2 of 8

Personal protection: Wear protective clothing and personal protective
equipment as prescribed in Section 8."Exposure Controls Personal Protection". Environmental Protection: Isolate and post spill area. Keep unprotected
persons and animals out of the area. Keep material out of streams and sewers. Vacuum or shovel into a drum and label content prior to disposal. Procedure: 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. 7. HANDLING AND STORAGE
Store in a cool, dry, well-ventilated place. Do not use or store near heat, open flame and 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 CONTROL/PERSONAL PROTECTION
Engineering controls: Ventilate all transport vehicles prior to unloading.
Eye/ Face protection: For splash, spray or mist exposure, wear chemical
protective goggles or face shield. Respiratory protection: For splash, spray or mist exposure wear, as a
minimum, a properly fitted half-face air purifying respirator which is approved for pesticides (U>S> NIOSH, MSHA, EU Cen or comparable certification Page 3 of 8

organization). Respirator use and selection must be based on airborne Hand protection: Wear chemical protective gloves made of materials such
as neoprene. Thoroughly wash the outside of gloves with soap and water prior to removal. Inspect regularly for leaks. Work 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 barner suit, such as a rubber rain 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). Personal hygiene: Clean water should be available for washing in case of
eye or skin contamination. Wash skin prior to eating, drinking or smoking. Shower at the end of the workday. 9. PHYSICAL AND CHEMICAL PROPERTIES

Boiling point: Not applicable.
Flash point: Not applicable.

Conditions to avoid: Excessive heat and fire
Hazardous decomposition products: Carbon monoxide and carbon dioxide.
Minor quantities of chlorine and hydrogen chloride may be formed. Hazardous polymerization: Will not occur.
Acute toxicity:
Oral: LD50 = 24000 mg/kg (rat).
Dermal: LD50 > 8000 mg/kg (rabbit).
Inhalation: LC50 = 9.2 mg/l, 4 hr (rat).
Effects from Overexposure: Permethrin has low oral, dermal and inhalation
toxicity, and is minimally irritating to eyes and practically non-irritating to the skin. Experience to date indicates that contact with Permethrin 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 of animals to Permethrin via inhalation has also produces hyperactivity and hypersensitivity. Chronic effects from overexposure: In studies with laboratory animals,
Permethrin did not cause reproductive toxicity or teratogenicity. analysis of chronic feeding studies in both 4/5 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 non-existent or extremely low. Long term feeding studies in animals resulted in increased liver and kidney Page 5 of 8

Physical environmental properties: The formulation is stable at a wide
range of pH values. Permethrin itself has a moderate rate of degradation in soil and the half-life is related to the soil type, microbial population, and 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 Environmental toxicology: Toxic to bees. Permethrin formulation is highly
toxic to fish (LC50+0.5µg/L to 7.6 µg/L). Marine species are often more sensitive than freshwater species. Bacteria, algae, molluscs and amphibians are much more tolerant of Permethrin than 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 up to 500 ppm diet had no effect on bird reproduction. 13. DISPOSAL CONSIDERATIONS
Open dumping or burning of this pesticide or its packaging is prohibited. Dispose of according to label instructions and environment ministry regulations Container which held these pesticides should be cleaned, prior to disposal, by triple-rinsing. Page 6 of 8
