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

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

Notes to Physician
There is no specific antidote if this product is ingested.
Treat symptomatically.
Probable mucosal damage may contraindicate gastric lavage.
Medical Condition Likely to be Aggravated by Exposure
Not available.
5. FIRE FIGHTING MEASURES
Fire and Explosion
Flash Point (Test Method): > 212癋
Flammable Limits (% in Air): Lower: % Not Applicable Upper: % Not Applicable
Autoignition Temperature: Not Available
Flammability: Not Flammable
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 outlined in Section 8.
Cover entire spill with absorbing material and place into 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. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
Skin Contact: Where contact is likely, wear chemical-resistant (such as nitrile or butyl) gloves, coveralls, socks and

FLEXSTAR
chemical-resistant footwear. For overhead exposure, wear chemical-resistant headgear.
Inhalation: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels
below exposure limits. A NIOSH-certified combination air-purifying respirator with an N, P or R 95 or HE
class filter and an organic vapor cartridge may be permissible under certain circumstances where airborne
concentrations are expected to exceed exposure limits. Protection provided by air-purifying respirators is
limited. Use a pressure demand atmosphere-supplying respirator if there is any potential for uncontrolled
release, exposure levels are not known, or under any other circumstances where air-purifying respirators
may not provide adequate protection.
