5. FIRE-FIGHTING MEASURES
Suitable extinguishing media: foam, dry chemical, carbon dioxide (CO2).
Extinguishing media which must not be used for safety reasons: water.
Special protective equipment for firefighters: In the event of fire, wear self-contained breathing
apparatus.
Specific methods: (on small fires) If area is heavily exposed to fire and if conditions permit, let
fire burn itself out since water may increase the area contaminated. Cool containers / tanks with spray
water.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Use personal protective equipment.
Environmental precautions: Do not flush into surface water or sanitary sewer system.
Methods for cleaning up: Clean up promptly by sweeping or vacuum. If spill area is on ground near
valuable plants or trees, remove 5 cm of top soil after initial clean-up. Use approved industrial
vacuum cleaner for removal. Shovel into suitable container for disposal.
7. HANDLING AND STORAGE
Handling
Technical measures/Precautions: Provide appropriate exhaust ventilation at places where dust is formed.
Safe handling advice: Use personal protective equipment. Keep away from heat and sources of ignition.
Storage
Technical measures/Storage conditions: Keep in a dry, cool and well-ventilated place. Keep containers
dry and tightly closed to avoid moisture absorption and contamination. Store in a place accessible by
authorized persons only.
Incompatible products: No materials to be specially mentioned.
Packaging material: No materials to be specially mentioned.
Further information: Keep out of reach of children.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering measures: Ensure adequate ventilation, especially in confined areas.
Control parameters:
Tribenuron methyl; DuPont鈥檚 acceptable exposure limit: AEL(8-h TWA) = 1 mg/m3; DuPont(1999)
Metsulfuron methyl; DuPont鈥檚 acceptable exposure limit: AEL(8-h and 12-h TWA) = 10 mg/m3; DuPont(1999)
Personal protective equipment
Respiratory protection: effective dust mask.
Eye protection: safety glasses.
Hand protection: protective gloves.
Hygiene measures: Wash hands before breaks and immediately after handling the product. Keep away from
food, drink and animal feeding stuffs. When using, do not eat, drink or smoke. For environmental
protection remove and wash all contaminated protective equipment before re-use. Dispose of rinse water
in accordance with local and national regulations.
