stinging.

Ingestion Hazards
Acute Ingestion Hazards: Moderately toxic by ingestion.

Section 4: First Aid Measures

First Aid for Eye: Use fingers to ensure that eyelids are separated and that the eye is
being irrigated. Get medical attention if irritation develops or
persists.

First Aid for Skin: In case of skin contact, wash affected areas with soap and water.
Contact a physician if irritation develops.

First Aid for Inhalation: If inhaled, remove to fresh air. If breathing is difficult, give oxygen.
Call a physician immediately.

First Aid for Ingestion: Contact a physician or Poison Control Center. If ingested, do not
induce vomiting unless directed to do so by medical personnel.

Note to Physician: Published data indicate vitamin E acetate can prevent and/or mitigate
symptoms of parasthesia caused by synthetic pyrethroids. In case of
human or animal poisoning, please contact the poison control center
at (800) 414-0244. Please also notify Bayer at (877) 258-2280.

Flammable Limits:
Upper Explosion Limit Not Applicable
(UEL %):
Lower Explosion Limit Not Applicable
(LEL %):
Extinguishing Media:
Suitable: Water, Foam, Dry Chemical

Special Fire Fighting Firefighters should be equipped with self-contained breathing

Procedures: apparatus to protect against potentially toxic and irritating fumes. Do
not allow fire fighting water to enter sewer, surface waters, or
ground water systems.

Section 6: Accidental Release Measures

Spill or Leak Procedures: Evacuate and keep unnecessary people out of spill area. Use
appropriate personal protective equipment during clean up. Avoid
creating dusty conditions. Collect and place in appropriately marked
sealable containers for disposal. Wash spill area with soap and water.
Do not allow spilled material or wash water to enter sewers, surface
waters, or groundwater systems. Collect wash water for approved
disposal.

Section 7: Handling and Storage

Storage Temperature:
Minimum: 0 °F
Maximum: 100 °F

Shelf Life: Contact Bayer for specific information.

Special Sensitivity: Not Established

Handling/Storage Precautions: Store separate from food products. Store in a dry place in orginal or
waterproof containers. Store in an area designated specifically for
pesticides.

Section 8: Exposure Controls/Personal Protection

Personal Protection Equipment

Eye Protection Requirements: Chemical safety goggles or glasses.

Skin Protection Requirements: Gloves, long sleeved shirts and pants., Highly chemically resistant
gloves (such as flexible laminated, eg. Silver Shield)

Ventilation Requirements: Under normal conditions of use, special ventilation is not required.

Respirator Requirements: A NIOSH approved air purifying respirator with organic vapor
cartridges and particulate prefilter can be used to minimize exposure.

Additional Protective Emergency showers and eye wash stations should be available. Note
Measures: that thorough washing with soap and water does not always totally
remove cyfluthrin from the hands. Waterless hand cleaner use is
often more effective than soap and water. Sensitive areas of the skin
and mucous membranes can become contaminated indirectly.
Educate and train employees in the safe use and handling of this
product. Follow all label instructions. Launder clothing separately
after use. Employees should wash their hands and face before eating,
drinking, or using tobacco products.

Section 11: Toxicological Information

Toxicity Data for Cylence Ultra

Toxicity Note: No data available for this product.

Toxicity Data for beta-Cyfluthrin

Acute oral toxicity: LD50 = 84 - 380 mg/kg bw (Male Rat)

LD50 = 77 - 651 mg/kg bw (Female Rat)

Acute dermal toxicity: LD50 = > 5,000 mg/kg bw (Rat)

Acute inhalation toxicity: LC50 = 0.08 mg/L, 4 hrs, aerosol (Rat)

LC50 = 0.53 mg/L, 4 hrs, dust/particulate (Rat)

Eye Irritation: Slightly irritating (Rabbit)

Skin Irritation: Slightly irritating (Rabbit)

Sensitization: non-sensitizer dermal (Guinea pig)

Repeated Dose Toxicity: In a 13 week dog study, beta-Cyfluthrin was administered at dietary
concentrations of 10, 60 or 360 ppm. Effects included vomiting and
diarrhea after feeding, decreased body weight gain, and motor
disturbances in the hind limbs. The no-observed effect-level
(NOEL) was 60 ppm. In a 13 week study using rats, beta-Cyfluthrin
was administered at dietary concentrations of 30, 125 or 500 ppm.
Effects included reduced body weight gains and feed consumption,
uncoordinated gait, and skin injuries of the neck and head from
excessive preening due to the local irritant effect of the test material.
The NOEL was 125 ppm. In a 4 week inhalation study, rats were
exposed to beta-Cyfluthrin at liquid aerosol concentrations of 0.2,
2.7 or 23.5 mg/m3. Effects observed included ungroomed fur,
piloerection, hyper- and hypoactivity, reduced body weight gains,
reduced organ weights (thymus and spleen), and hematological
changes. The NOEL was 0.2 mg/m3 based on decreased body
weight gains.

Mutagenicity: No mutagenic effects were determined in various in vivo and in vitro

tests.

Developmental In a developmental toxicity study, beta-Cyfluthrin was administered
Toxicity/Teratogenicity: orally to rats during gestation at doses of 3, 10 or 40 mg/kg. At the
lethal and maternally toxic dose of 40 mg/kg, there was a decrease in
fetal body weights and an increased incidence of skeletal findings.
The NOELs for maternal and developmental toxicity were 3 and 10
mg/kg, respectively.

Neurotoxicity: In a 13 week neurotoxicity screening study, beta-Cyfluthrin was

administered to rats at dietary concentrations of 30, 125, or 400 ppm.
Effects observed included reduced body weight and food
consumption, ataxia, repetitive chewing and pawing, increased
activity and reactivity, and red nasal stain. There were no
micropathologic findings within the neural tissues or skeletal
muscle. The NOEL for subchronic neurotoxicity was 400 ppm, the
highest dose tested. The overall NOEL was 30 ppm.

Toxicity Data for Heterocyclic compound

Acute oral toxicity: LD50 = 6,150 mg/kg bw (Rat)

Acute dermal toxicity: LD50 = 200 mg/kg bw (Rabbit)
