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

Notes to Physician
There is no specific antidote if this product is ingested.
Contact with eyes may require specialized ophthalmologic attention.
Persons suffering with temporary allergic skin reactions may respond to treatment with oral antihistamines and topical or
oral steroids.

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 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. 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

RIDOMIL GOLD/BRAVO
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
chemical-resistant footwear. For overhead exposure, wear chemical-resistant headgear.
Inhalation: A particulate filter respirator may be necessary until effective engineering controls are installed to comply
with occupational exposure limits. Use a NIOSH approved respirator with any HE filter.
Use a self-contained breathing apparatus in cases of emergency spills, when exposure levels are unknown, or
under any circumstances where air-purifying respirators may not provide adequate protection.

in absolute liver and kidney weights.
Neurotoxicity: No evidence in regulatory studies.
Liver effects at high dose animal tests.
Mefenoxam:
Carcinogenicity
Chlorothalonil: No evidence of carcinogenicity in dogs after administration for up to one year. Treament related
increases in the incidence of renal tubular adenoma and carcinoma were observed in rats and male
mice. Squamous cell adenomas and carcinomas were also observed in the forestomach of both
species. The forestomach tumors seen in rodent studies are not relevant to human health, as humans
do not possess an anatomical equivalent of the rodent forestomach. The relevance of renal tumors
to human health is unclear, although metabolism data suggest that the dog, a species that is resistant
to chlorothalonil-induced renal injury, may be more representative of humans than the rat. IARC
identifies chlorothalonil as a 2B carcinogen (possibly carcinogenic to humans).
Mefenoxam: None observed.
Other Toxicity Information
Studies on rats and mice have suggested that technical chlorothalonil (97%), when fed at high levels in the diet, may have
oncogenic potential to these laboratory animals. However, neither chlorothalonil nor its metabolites interact with DNA and
thus are not mutagenic. Tumor formation has been related to a non-genotoxic mechanism of action for which threshold
levels have been established in rats and mice. Comprehensive dietary and worker exposure studies have shown exposure
levels for humans to be well below these threshold levels. In addition, surveillance of chlorothalonil plant workers for over
twenty years has not demonstrated any increase in oncogenic potential to humans.
May cause sensitization by skin contact. Exposure of the skin to chlorothalonil may result in weak contact dermatitis.
Toxicity of Other Components
Amorphous Silica
Amorphous Silica is listed as an IARC (Group 3) carcinogen not classifiable as a human carcinogen (No Data
Available) with limited animal evidence. Prolonged exposure to amorphous silica may cause damage to respiratory
system and irritation to skin and eyes.
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.
