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
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.
