III. Health Hazard Data
EYE: May cause eye irritation, but does not cause irreversible damage to eye tissue.
SKIN CONTACT: May cause moderate skin irritation with prolonged or repeated contact. In rare
instances, exposure to this product may cause numbing, burning and tingling sensations. These effects are
reversible and usually subside within 12 hours.
SKIN ABSORPTION: The acute dermal toxicity is considered to be low. The dermal LD50 for rabbits
is greater than 2000 mg/kg.
INGESTION: The acute oral toxicity is considered to be low. The oral LD50 for rats is greater than 1000
mg/kg. Small amounts that might be swallowed incidental to normal handling operations are not likely to
cause injury; however, swallowing larger amounts may cause serious injury, even death. If aspirated
(liquid enters the lungs), may cause lung damage or even death due to chemical pneumonia.
INHALATION: The acute inhalation toxicity is considered to be low. The inhalation LC50 for rats is
greater than 4 mg/l for 4 hours. Symptoms of excessive exposure includes squinting eyes, irregular and
rattled breathing, ataxia, headache, dizziness, anesthesia, drowsiness, unconsciousness, and other central
nervous system effects.
SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Excessive exposure may produce effects on
the nervous system such as sensitivity to touch and sound, tremors, abnormal movement, and clonic
convulsions. Long-term studies with permethrin in laboratory animal resulted in increased liver and
kidney weights, induction of the liver microsomal drug metabolizing enzyme system, and
histopathological changes in the lungs and liver. Long-term studies with piperonyl butoxide indicated
increased organ weights in the liver, kidney, and adrenal glands.
CANCER INFORMATION: Chronic feeding studies with permethrin in mice and rats indicate limited
evidence of oncogenicity in laboratory animals. Based on comprehensive evaluations of all relevant
health effects data, it was concluded that the oncogenic potential in humans is extremely weak or
nonexistent. A chronic feeding study in mice indicate an increased incidence of benign liver tumors; the
significance of these findings is questionable and under review. The doses that produced this oncogenic
effect in laboratory animals, greatly exceeds human exposure levels for the recommended use of this
TERATOLOGY (BIRTH DEFECTS): The active ingredients in this product did not cause birth
defects in laboratory animal studies. Exposures having no effect on the mothers had no effect on the
fetuses in rabbits and rats. The no-effect levels for permethrin in rabbits and rats were 600 mg/kg and 50
mg/kg, respectively. The no-effect levels for piperonyl butoxide in rabbits and rats were 200 mg/kg and
1000 mg/kg, respectively.

REPRODUCTIVE EFFECTS: Permethrin and piperonyl butoxide did not interfere with fertility in
animal reproduction studies. The no effect level for permethrin in a two-generation rat reproduction study
was 180 mg/kg. The no-effect level for piperonyl butoxide in a two-generation rat reproduction study was
MUTAGENICITY (EFFECTS ON GENETIC MATERIAL): Based on a number of in vivo and in
vitro studies, it was concluded that the active ingredients in this product are not mutagenic.
IV. First Aid Procedures
EYES: Hold eye open and rinse slowly and gently with water for 15 minutes. Remove contact lenses, if
present, after the first 5 minutes, then continue rinsing eye. Call a poison control center or doctor for
SKIN OR CLOTHING: Take off contaminated clothing. Rinse skin immediately with plenty of water
for 15 to 20 minutes. Call a poison control center or doctor for treatment advise.
INGESTION: Immediately call a poison control center or doctor. Do not induce vomiting unless told to
do so by a poison control center or doctor. Do not give any liquid to the person. Do not give anything by
mouth to an unconscious person.
INHALATION: Remove person to fresh air. If person is not breathing, call 911 or an ambulance, then
give artificial respiration, preferably mouth-to-mouth, if possible. Call a poison control center or doctor
for further advise.
NOTE TO PHYSICIAN: This product has low oral, dermal, and inhalation toxicity. It is moderately
irritating to the skin and is may be irritating to the eyes. Reversible skin sensations (paresthesia) may
occur and skin salves have been found useful in reducing discomfort. Contains a petroleum distillate
solvent that can produce a severe pneumonitis or fatal pulmonary edema if aspirated during vomiting.
Consideration should be given to gastric lavage with an endotracheal tube in place. Treatment is
controlled removal of exposure followed by symptomatic and supportive care.

VI. Environmental Protection
IN CASE OF SPILLS OR LEAKS: Wear protective clothing as described in Section VII (Personal
Protection and Precautions) of this MSDS. Absorb liquid with material such as clay, sand, sawdust, or
dirt. Sweep up and place in a suitable container for disposal and label the contents. Area can be
washed down with a suitable solution of bleach or soda ash and an appropriate alcohol (methanol,
ethanol, or isopropanol). Follow this by washing with a strong soap and water solution. Absorb any
excess liquid as indicated above, and add to the disposal container. Keep product, contaminated
materials and wash water out of streams and sewers. Wash exposed body areas thoroughly after

DISPOSAL METHOD: Do not contaminate food, feed, or water by storage or cleaning of equipment.
Wastes resulting from the use of this product may be disposed of on site, if approved waste handling
facilities are available, or at an approved waste handling facility.
PHYSICAL ENVIRONMENTAL PROPERTIES: In soil, permethrin is stable over a wide range of
pH values. 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. Piperonyl butoxide is reported
to have a maximum half-life of 4.3 days in soil and from 0.55 to 1.64 days in aqueous environments.
Gravitational settling remove piperonyl butoxide released in the atmosphere as an aerosol. Gaseous
piperonyl butoxide degrades in the atmosphere with an estimated half-life of 3.4 hours. It is reported that
piperonyl butoxide has a low potential for environmental bioconcentration.
ENVIRONMENTAL TOXICOLOGY: Permethrin is highly toxic to fish (LC50 = 0.5 碌g/L to 315
碌g/L) and aquatic invertebrates (LC50 = 0.02 碌g/L to 7.6 碌g/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 3,600 mg/kg.
Longer dietary studies showed that concentrations of up to 500 ppm in the diet had no effect on bird
reproduction. Piperonyl butoxide is acutely toxic to fish (LC50 = 3.94 mg/L to 6.12 mg/L) and highly
toxic to aquatic invertebrates (LC50 0.23 mg/L to 0.51 mg/L). Care should be taken to avoid
contamination of aquatic environments. Piperonyl butoxide has a low to very low toxicity to birds with an
acute oral LD50 greater than 2,250 mg/kg and longer-term dietary studies at LC50 values greater than

Permethrin None established.
Piperonyl Butoxide None established
5 mg/m3 (oil mist).
VENTILATION: Provide general and/or local exhaust ventilation to control airborne levels below the
exposure guideline. Ventilate all transport vehicles prior to unloading.
RESPIRATORY PROTECTION: Atmospheric levels should be maintained below the exposure
guideline. For most conditions, no respiratory protection should be needed; however, if the exposure
guideline is exceeded, use an air-purifying respirator approved for pesticides (U.S. NIOSH/MSHA, EU
CEN, or comparable certification organization).

EYE/FACE PROTECTION: Use chemical protective goggles or a face shield.
SKIN PROTECTION: Wear coveralls or long-sleeved shirt and long pants, chemical protective gloves
(nitrile, neoprene, or Viton庐 brand), head covering and shoes plus socks. For increased exposures, wear a
full body cover barrier suit, such as a PVC rain suit. Contaminated leather articles, such as shoes, belts,
and watchbands, should be removed and destroyed. Launder all work clothing before reuse. Keep work
clothing separated from household laundry.
SPECIAL PRECAUTIONS FOR HANDLING AND STORAGE: See product label. Harmful if
swallowed, inhaled, or absorbed through the skin. Do not get in eyes, on skin, or on clothing. Wash
thoroughly with soap and water after handling and before eating or smoking. Avoid breathing dust vapor,
or spray mist. Store in a cool, dry place and away from heat. Keep out of reach of children and animals.
Keep away from food, feedstuffs, and water supplies.
