3. HAZARDS IDENTIFICATION
Symptoms of Acute Exposure
May cause mild eye irritation.
Hazardous Decomposition Products
Can decompose at high temperatures forming toxic gases.
Physical Properties
Appearance: Off-white/buff/beige liquid
Odor: Not available
Unusual Fire, Explosion and Reactivity Hazards
This product will burn with flames if ignited. This product has a minimum ignition energy between 100 and 300 millijoules.
Mechanical sparks, open flames, and certain hot surfaces can serve as ignition sources for this material. Eliminate the presence
of mechanical sparks and other ignition sources where dust clouds of this material could form.
During a fire, irritating and possibly toxic gases may be generated by thermal decomposition or combustion.

Ingestion: If swallowed: Call a poison control center of 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 a poison control
center or doctor. Do not give anything by mouth to an unconscious person.
Eye Contact: If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses,
if present, after 5 minutes, then continue rinsing eye. Call a poison control center or doctor for treatment
advice.
Skin Contact: If on skin or clothing: Take of contaminated clothing. Rinse skin immediately with plenty of water for 15-
20 minutes. Call a poison control center of doctor for treatment advice.
Inhalation: If inhaled: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give artificial
respiration, preferably mouth-to-mouth if possible. Call a poison control center or doctor for further
treatment advice.

5. FIRE FIGHTING MEASURES
Fire and Explosion
Flash Point (Test Method): Does not flash
Flammable Limits (% in Air): Upper: % Not Applicable Lower: % Not Applicable
Auto ignition Temperature: Not Available
Flammability: Not Applicable
Unusual Fire, Explosion and Reactivity Hazards
This product will burn with flames if ignited.
This product has a minimum ignition energy between 100 and 300 millijoules. Mechanical sparks, open flames, and certain
hot surfaces can serve as ignition sources for this material. Eliminate the presence of mechanical sparks and other ignition
sources where dust clouds of this material could form.
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. 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
Product Name: CAMBISTAT 2SC Page: 2
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 is not considered electrically conductive at low relative humidity.
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 AND PACKAGING OF THE PRODUCT.
FOR COMMERCIAL APPLICATIONS AND/OR ON-FARM APPLICATIONS CONSULT THE PRODUCT LABEL
Ingestion: Prevent eating, drinking, tobacco usage and cosmetic application in areas where there is a potential for
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.
