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

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, if
Eye Contact:
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.

5. FIRE FIGHTING MEASURES
Fire and Explosion
Flash Point (Test Method): > 221癋
Flammable Limits (% in Air): Lower: Not Applicable Upper: Not Applicable
Autoignition Temperature: 977癋
Flammability: Not Applicable
Unusual Fire, Explosion and Reactivity Hazards
This product may form flammable and explosive hydrogen gas when in contact with galvanized or unlined steel.
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. 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
