Section 3: Hazards Identification
Primary Routes of Entry: Eye and skin contact.
Causes irreversible eye damage. Prolonged or frequent repeated skin contact may cause allergic reaction
in some individuals.
Symptoms of Acute Exposure
Large, toxic doses of the active ingredient in this product administered to laboratory animals have
produced central nervous system effects with symptoms that include diarrhea, salivation, bloody nose,
tremors and intermittent convulsions. Overexposure to permethrin via inhalation also produced
hyperactivity and hypersensitivity.
Section 4: First Aid Measures
Ingestion: Call a physician or Poison Control Center. Do not induce vomiting or give anything by
mouth to an unconscious person. Drink promptly a large quantity of skim milk, egg whites, gelatin
solution, or, if these are not available, large quantities of water. Avoid alcohol. This product contains
aromatic petroleum solvent. Aspiration may be a hazard.

Eye Contact: Flush eyes with plenty of water. Get medical attention.
Skin Contact: Wash with plenty of soap and water. Call a physician if irritation persists.
Inhalation: Move person to fresh air. Apply artificial respiration if necessary, preferably mouth to
mouth. Get immediate medical attention.
Notes to Physician
Induction of emesis is not recommended due to the large amount of petroleum solvent in this product,
which could cause chemical pneumonia if aspirated. If ingested, lavage stomach, taking care to avoid
aspiration of stomach contents into lungs. Check for possible mucosal damage before beginning gastric
lavage. This product contains a pyrethroid. If a small amount is ingested, or if treatment is delayed, oral
administration of large amounts of activated charcoal and a cathartic is probably sufficient therapy. Do
not administer milk, cream or other substances containing vegetable of animal fats, which enhance the
absorption of lipophilic substances.
Section 5: Fire Fighting Measures
Fire and Explosion
105-112oF (TCC)
Flash Point (Test Method):
Upper: 12.6 @ 77 oF (approximate 鈥? solvent)
Flammable Limits (% in air): Lower: 1.9
o
Autoignition temperature: 880 F (approximate 鈥? solvent)
Unusual Fire, Explosion and Reactivity Hazards
The solvent in this product is a combustible liquid. Can form combustible mixtures at temperatures that
are at or above the flash point.
In case of Fire
Use water fog, dry chemical, foam or CO2 extinguishing media. Wear full protective clothing and self-
contained breathing apparatus. Evacuate nonessential personnel from the area to prevent human
exposure to fire, smoke, fumes or products of combustion. Prevent use of contaminated buildings, area
and equipment until decontaminated. Use as little water as possible to prevent spread of contaminated
runoff.
Section 6: Accidental Release Measures
Wear chemical safety glasses with side shields or chemical goggles, rubber gloves, rubber boots, long-
sleeved shirt, long pants, to prevent contact with spilled material. For small spills, cover the spill with an
absorbent material such as pet litter. Sweep up and place in an approved chemical container. Wash the
spill area with water containing a strong detergent, absorb with pet litter or other absorbent material,
sweep up and place in a chemical container. Seal the container and handle in an approved manner. Flush
the area with water to remove any residue. Do not allow wash water to contaminate water supplies.
Section 7: Handling and Storage
Store the material in a well-ventilated, secure area, out of the reach of children and domestic animals. Do
not store food, beverages or tobacco products in the storage area. Prevent eating, drinking, tobacco
usage, and cosmetic application in areas where there is a potential for exposure to the material. Always
wash thoroughly after handling.

Toxicity of Other Components:
Petroleum solvent: The supplier reports that inhalation of high vapor concentrations (over 1,000
ppm) may cause nervous system effects such as headaches, dizziness, anesthesia and respiratory
tract irritation
Emulsifiers: Cause severe eye irritation, which could lead to permanent eye damage. Prolonged
or repeated skin contact may cause discomfort and local redness. Mist can irritate the respiratory
tract, experienced as nasal discomfort and discharge with chest pain and coughing.
Section 12: Ecological Information
