3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
http://www.fmc-apgspec.com/msds/Cynoff%20EC.htm 01/09/2002
CYNOFF?EC INSECTICIDE Page 3 of 12
IMMEDIATE CONCERNS: - Amber liquid with a soapy odor.
- Slightly combustible. May support combustion at elevated temperatures.
- Thermal decomposition and burning may form toxic by-products.
- For large exposures or fire, wear personal protective equipment.
- Highly toxic to fish and aquatic organisms. Keep out of drains and water courses.
- Expected to be moderately irritating to the skin and eyes.
POTENTIAL HEALTH EFFECTS: Effects from overexposure result from inhalation or coming into
contact with the eyes or skin. Symptoms of overexposure include decreased activity, tremors,
convulsions, loss of bladder control, incoordination, and increased sensitivity to sound. Contact with
cypermethrin may produce skin sensations such as numbing, burning and tingling. These skin sensations
are reversible and usually subside within 12 hours.
MEDICAL CONDITIONS AGGRAVATED: None presently known.
4. FIRST AID MEASURES
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
expected to be moderately irritating to the eyes and skin. It contains cypermethrin, a pyrethroid
insecticide. Do not administer milk, cream or other substances which contain vegetable or animal
fats, as they enhance absorption. Central nervous system stimulation should be controlled with
sedation by, e.g., barbiturates. The formulation contains phenylsulfonate, a corrosive material.
Consideration should be given to gastric lavage with an endotracheal tube in place. 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.

6. ACCIDENTAL RELEASE MEASURES
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 of caustic or
soda ash, and an appropriate alcohol (i.e., methanol, ethanol or isopropanol). Follow this by washing
with a strong soap and water solution. Absorb, as above, any excessive 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 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 butyl rubber, nitrile 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 guidance for individuals whose
use or handling of this product is not guided by the product label.

ACUTE EFFECTS FROM OVEREXPOSURE: This product has low oral, dermal and
inhalation toxicity. It is expected to be moderately irritating to the eyes and skin. Large doses of
cypermethrin ingested by laboratory animals produced signs of toxicity including loss of motor
control, tremors, decreased activity, urinary incontinence, incoordination, increased sensitivity to
sound and convulsions. Experience to date indicates that contact with cypermethrin may produce
skin sensations such as numbing, burning or tingling. These sensations are reversible and usually
subside within 12 hours. Contact with phenylsulfonate may be corrosive to the skin and severely
irritating to the eyes. Exposure to butanol vapors may produce headaches, drowsiness and irritation
of the nose and throat. Excessive exposures to butanol liquid or vapors may result in contact
dermatitis and irritation of the mucous membranes.
CHRONIC EFFECTS FROM OVEREXPOSURE: No data available for the formulation. In
studies with laboratory animals, cypermethrin did not cause reproductive toxicity, teratogenicity,
neurotoxicity or carcinogenicity in male and female rats and male mice. Cypermethrin caused an
increase in benign lung tumors in female mice at 1600 ppm in the diet. The EPA concluded on a
weight of evidence approach that cypermethrin represents a low oncogenic potential to female mice
at this dose level (approximately 228 mg/kg/day). Liver enlargement is often noted in laboratory
animals that have ingested large doses of cypermethrin during their life span. An overall absence of
genotoxicity has been demonstrated in tests of mutagenicity, DNA damage and chromosome
aberrations. Disturbances in hearing and balance have been reported in workers exposed to butanol
vapors.

12. ECOLOGICAL INFORMATION
Unless otherwise indicated, the data presented below are for the active ingredient.
ENVIRONMENTAL DATA: When applied at agricultural use rates, cypermethrin has a moderate
rate of degradation in the soil. At termiticidal use rates, cypermethrin degrades at a slower rate
which is governed by soil characteristics (e.g., pH). The rate of cypermethrin hydrolysis is somewhat
faster under alkaline conditions than at neutral or acidic pH. Cypermethrin has a high affinity for
organic matter and a Log Pow of 5.0, but has demonstrated a low potential for bioconcentration
(BCF = 17). Cypermethrin is not mobile in soil.
ECOTOXICOLOGICAL INFORMATION: Cypermethrin is considered highly toxic to fish and
aquatic arthropods, and has LC50 values which range from 0.004 礸/L to 3.6 礸/L. The aquatic
arthropods tended to be some of the more sensitive species. Care should be taken to avoid
contamination of the aquatic environment. Cypermethrin is slightly toxic to birds and oral LD50
values are greater than 10,248 mg/kg.
