3. HAZARDS IDENTIFICATION
Symptoms of Acute Exposure
May cause eye irritation. Harmful if inhaled, swallowed or absorbed through the skin.
Hazardous Decomposition Products
Flammable hydrogen gas may be formed on contact with aluminum. See "Conditions to Avoid", Section 10.
Can decompose at high temperatures forming toxic gases.
Physical Properties
Appearance: Dark brown liquid

Notes to Physician
To be effective, treatment for ingestion of the product must begin IMMEDIATELY. Treatment consists of binding the
active ingredient, diquat, in the gut with suspensions of activated charcoal or bentonite clay, administration of cathartics
to enhance elimination and removal of diquat from the blood by charcoal hemoperfusion or continuous hemodialysis.
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 Applicable
Flammability: Not Applicable
Unusual Fire, Explosion and Reactivity Hazards
This product may form flammable and explosive hydrogen gas when in contact with aluminum.
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
This product reacts with aluminum to produce flammable hydrogen gas. Do not mix or store in containers or systems made of
aluminum or having aluminum fittings.
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.
