3. HAZARDS IDENTIFICATION
Symptoms of Acute Exposure
Causes mild eye and skin irritation. Allergic skin reactions are possible.
Hazardous Decomposition Products
Can decompose at high temperatures forming toxic gases.
Physical Properties
Appearance: Yellow granules
Odor: Odorless
Unusual Fire, Explosion and Reactivity Hazards
This product is considered electrically conductive. Static electricity, mechanical sparks, open flames and certain hot
surfaces (greater than 680掳F [360掳C]) can serve as ignition sources for this material.
During a fire, irritating and possibly toxic gases may be generated by thermal decomposition or combustion.
4. FIRST AID MEASURES
Product Name: Page: 1
BARRICADE 65WG HERBICIDE
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.
Medical Condition Likely to be Aggravated by Exposure
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 Flammable
Unusual Fire, Explosion and Reactivity Hazards
This product is considered electrically conductive. Static electricity, mechanical sparks, open flames and certain hot
surfaces (greater than 680掳F [360掳C]) can serve as ignition sources for this material.
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 it from spreading, contaminating soil, or entering sewage and
drainage systems or any body of water. Clean up spills immediately, observing precautions outlined in Section 8. If a
solid, sweep up material and place in a compatible disposal container. If a liquid, 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.
Handle this material only in electrically conductive equipment. Electrically ground and bond this equipment as well as any

worker who could contact a dust cloud formed of this material. Eliminate the presence of mechanical sparks and other
ignition sources where dust clouds of this material could form. Bulk bags (FIBC) used to contain this material should be
either type B or type C. If type C bags are used make sure they are electrically grounded before powder is discharged from the
bag. This material is considered explosion class (Kst) 2. This material can energetically decompose at approximately 383掳F
(195掳C). Do not store or process at temperatures above 320掳F (160掳C).
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: 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.
