4. FIRST AID MEASURES
Have the product container, label or Material Safety Data Sheet with you when calling Syngenta (800-888-8372), a poison
contol center or doctor, or going for treatment.
If swallowed: Call Syngenta (800-888-8372), a poison control center or doctor immediately for treatment
Ingestion:
advice. Have the person sip a glass of water if able to swallow. Do not induce vomiting unless told to do so
after calling 800-888-8372 or by a poison control center or doctor. Do not give anything by mouth to an
unconscious person.
If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses,
Eye Contact:
if present, after 5 minutes, then continue rinsing eye. Call Syngenta (800-888-8372), a poison control center
or doctor for treatment advice.
Skin Contact: If on skin or clothing: Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-
20 minutes. Call Syngenta (800-888-8372), a poison control center or doctor for treatment advice.
If inhaled: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give artificial
Inhalation:
respiration, preferably mouth-to-mouth if possible. Call Syngenta (800-888-8372), a poison control center or
doctor for further treatment advice.
Notes to Physician
There is no specific antidote if this product is ingested.
Treat symptomatically.

None known.
5. FIRE FIGHTING MEASURES
Fire and Explosion
Flash Point (Test Method): Not Applicable
Flammable Limits (% in Air): Lower: % Not Applicable Upper: % Not Applicable
Autoignition Temperature: Not Available
Flammability: Not Applicable
Unusual Fire, Explosion and Reactivity Hazards
During a fire, irritating and possibly toxic gases may be generated by thermal decomposition or combustion.
In Case of Fire
Use 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. Water runoff can cause
environmental damage. If water is used to fight fire, dike and collect runoff.
6. ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Control the spill at its source. Contain the spill to prevent from spreading or contaminating soil or from entering sewage
and drainage systems or any body of water. Clean up spills immediately, observing precautions in Protective Equipment
Section. Sweep up material and place in a compatible disposal container. Scrub area with hard water detergent (e.g.
commercial products such as Tide, Joy, Spic and Span). Pick up wash liquid with additional absorbent and place into
compatible disposal container. Once all material is cleaned up and placed in a disposal container, seal container and
arrange for disposition.
7. HANDLING AND STORAGE
Store the material in a well-ventilated, secure area out of reach of children and domestic animals. Do not store food, beverages
or tobacco products in the storage area. Prevent eating, drinking, tobacco use, and cosmetic application in areas where there is
a potential for exposure to the material. Wash thoroughly with soap and water after handling.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
THE FOLLOWING RECOMMENDATIONS FOR EXPOSURE CONTROLS/PERSONAL PROTECTION ARE INTENDED FOR
THE MANUFACTURE, FORMULATION, PACKAGING AND USE OF THIS PRODUCT.
FOR COMMERCIAL APPLICATIONS AND/OR ON-FARM APPLICATIONS CONSULT THE PRODUCT LABEL.
Prevent eating, drinking, tobacco usage and cosmetic application in areas where there is a potential for
Ingestion:
exposure to the material. Wash thoroughly with soap and water after handling.
Eye Contact: Where eye contact is likely, use chemical splash goggles.
Skin Contact: Where contact is likely, wear chemical-resistant (such as nitrile or butyl) gloves, coveralls, socks and
chemical-resistant footwear. For overhead exposure, wear chemical-resistant headgear.
Inhalation: A respirator is not normally required when handling this substance. Use effective engineering controls to
comply with occupational exposure limits.
In case of emergency spills, use a NIOSH approved respirator with any N, R, or P or HE filter.

Toxicity of Other Components
Kaolin Clay
Long term exposure to high concentrations of this dust may produce x-ray evidence of dust in the lungs.
Continued long term overexposure may affect respiratory function in some individuals.

Effects of overexposure: No information found for this material. It is anticipated that inhalation of significant
quantities of this material will produce decreased lung capacity as is typical of nuisance dusts. Individuals who
are sensitized to formaldehyde might exhibit allergic reactions from contact with this material.
