SECTION 6 Health Hazard Assessment (Toxicological Information)
Acute Effects from Overexposure
General: WayLay 3.2 AG has low oral, dermal and inhalation toxicity. It is minimally irritating to the eyes and
slightly irritating to the skin.
Ingestion: Vomiting after ingestion of this product may cause aspiration of hydrocarbon solvents into the lungs
that may result in fatal pulmonary edema.
Skin contact: Experience to date indicates that contact with permethrin has rarely produced skin sensations
such as numbing, burning or tingling. These skin sensations are reversible and usually subside within 12
hours. Large toxic doses of WayLay 3.2 AG administered to laboratory animals have produced central
nervous system effects with symptoms that include hypersensitivity to touch and sound, tremors, and clonic
convulsions.
Inhalation: Overexposure to animals via inhalation has also produced symptoms such as squinting eyes,
irregular and rattling breathing and ataxis. Inhalation of hydrocarbon solvent vapors may cause dizziness,
disturbances in vision drowsiness, respiratory irritation, and eye, skin and mucous membrane irritation.
Chronic Effects from Overexposure
No data available for WayLay 3.2 AG. 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鈥檚 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 mutagenicity testing with permethrin. Chronic
exposure to hydrocarbon solvents may cause headaches, dizziness, loss of sensations or feelings, and liver
and kidney damage.
Carcinogenicity: IARC: No NTP: No Other (OSHA): No

SECTION 7 Health Hazard Assessment
First Aid Procedures:
Skin: Wash with plenty of soap and water. Get medical attention if irritation occurs and persists.
Eyes: Flush with water for at least 15 minutes. If irritation occurs and persists, obtain medical attention.
Inhalation: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, obtain medical
attention.
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.
Note to Medical Doctor: WayLay 3.2 AG has low oral, dermal and inhalation toxicity. It is minimally irritating to
the eyes and slightly irritating to the skin. The low oral toxicity of the product compared to the risk of
pneumonitis from aspiration of hydrocarbon solvents suggests vomiting should not be induced. Consideration
should be given to gastric lavage with an endotracheal tube in place. Activated charcoal and cathartic are
recommended and nervous stimulation should be controlled with a sedative, e.g. barbiturates. Reversible
skin sensations (paresthesia) may occur and ordinary skin salves have been found useful in reducing
discomfort. Treatment is otherwise controlled removal of exposure followed by symptomatic and supportive
care.

SECTION 9 Spill or Leak Procedures
ACCIDENTAL RELEASE MEASURES
Isolate and post spill area. Wear protective clothing and personal protective equipment as prescribed in
Section 8 鈥淪pecial Protective Information鈥?. Keep unprotected persons and animals out of the area.
Keep material out of streams and sewers. Dike to confine spill and absorb with an absorbent such as clay,
sand or soil. Vacuum, shovel or pump waste into a drum and label content.
To clean and neutralize spill area, tools and equipment, wash with a suitable solution of caustic or soda ash
and an appropriate alcohol (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 鈥淒isposal
Considerations鈥?.
DISPOSAL CONSIDERATIONS
Open dumping or burning of this pesticide 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 regulatory agencies should be contacted prior to disposal.
Non-returnable containers that 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 rinsate being
incinerated. Do not cut or weld metal containers. Vapors that form may create an explosion hazard.

original containers only. Store at temperatures above 40 F (5 C). If crystals form, warm to room temperature
70 F (21 C) by room heating only for 24-48 hours, and shake occasionally until crystals dissolve and product
appears uniform. Do not use external source of heat for warming container. Keep out of reach of children
and animals. Do not contaminate other pesticides, fertilizers, water, food or feed by storage or disposal.
ENVIRONMENTAL INFORMATION
Unless indicated, the information presented below is for the active ingredient, permethrin.
Physical/Environmental Properties
In soil, permethrin is stable over a wide range of pH values. When applied at agricultural use rates,
permethrin has a moderate rate of degradation in soil. At termiticidal use rates, permethrin degrades at a
slower rate, which is governed by soil characteristics. Due to 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 a
low potential to bioconcentrate (BCF = 500) due to the ease with which it is metabolized.
Environmental Toxicology
Permethrin is highly toxic to fish (LC50 = 0.5ug/L to 315 ug/L) and aquatic arthropods (LC50 = 0.02 ug/L to
7.6 ug/L). Marloe 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.
