Extinguishing Media: [] Foam [] Alcohol Foam [X] Dry Chemical
[X] Water Spray [] Other [] CO2
Special Fire-Fighting Procedures: Wear self-contained breathing apparatus. Use water spray. Cool tank/container with water
spray. If area is heavily exposed to fire and if conditions permit, let fire burn itself out since water may increase the area
contamination. Dike runoff from entering drains, sewers or water sources.
Unusual Fire and Explosion Hazards: Under severe dusting conditions, this material may form explosive mixtures in the air.
5. HAZARDS IDENTIFICATION
Primary Route(s) of Entry: Skin, eyes, inhalation, ingestion.
Signs & Symptoms of Exposure
Acute: May irritate eyes, nose, throat and skin. Not a skin sensitizer. Produced very mild conjunctival irritation and slight
corneal cloudiness in rabbits. Eyes were normal within 4 days.
Chronic: NOEL in diet was established at 500 ppm. Test animals experienced a moderate reduction in body weight in a daily
feeding study over two years.
Dietary: Administration of 0, 100, 500, and 2,500 ppm chlorsulfuron to male and female young adult dogs for 6 months
produced a no-observable-effect level (NOEL) of 2,500 ppm in the diet. No compound-related changes in nutritional, clinical,
biochemical, gross or histopathological observations were made.
Administration of 0, 100, 500, and 2,500 ppm chlorsulfuron to male and female weanling rats for 2 years produced a NOEL of
100 ppm in the diet based on mild to moderate reduction in mean body weights and weight gains in male rats from the higher
dose groups.
Oncogenicity studies conducted with male and female mice by dietary administration of 0, 100, 500 and 5,000 ppm chlorsulfuron
for 2 years showed no compound-related behavioral, clinical, hematological, gross pathological, or histological abnormalities.
Chlorsulfuron was not oncogenic at any level. The overall NOEL was 500 ppm as a body weight reduction occurred in the 5,000
ppm level.
Reproduction: (rats) The dietary presence of chlorsulfuron at 500 ppm had no adverse effect on the reproduction or lactation
performance of young adult rats (3-generation, 2-litters per generation).
Teratogenicity: Not teratogenic in rats at 2,500 ppm or up to 75 mg/kg in rabbits.
Mutagenicity: Not mutagenic in Ames bacterial assay, Chinese Hamster Ovary mammalian cell assay, rat dominants lethal assay,
in vitro cytogenetic assay, or DNA repair assay.
No data is available to confidently predict the effects of overexposure to humans; however, based on animal studies, human health
effects of overexposure by inhalation, ingestion, or skin or eye contact may initially include: eye irritation with discomfort, tearing
or blurring of vision, or irritation of the upper respiratory passages.
Emergency First-Aid Procedures
Eyes: Flush eyes with plenty of water for 15 minutes. Call a physician.
Skin: Wash with soap and water. Wash contaminated clothing before reuse.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. Call a physician.
Ingestion: Immediately give two glasses of water and induce vomiting. Never give anything by mouth to an unconscious person.
Call a physician.
Toxicity Information:
Oral LD50: 5,000 mg/kg (acute, rat) Dermal LD50: >2,000 mg/kg (acute, rabbit)
Inhalation LC50: (rat): ND Eye Irritation: Moderate but reversible.
Skin Irritation: Not a skin irritant or sensitizer.
Positive Teratogen or Mutagen Carcinogen (NTP): No Potential Carcinogen (IARC or OSHA): No
6. REACTIVITY
Stability: Stable at normal temperatures and storage conditions.
Conditions to Avoid: Avoid high temperatures for storage.
Incompatibility: None reasonably foreseeable.
Hazardous Decomposition Products: May produce noxious gases at very high temperatures.
Hazardous Polymerization: [X] Will not occur [ ] Will occur
7. SPILL, LEAK, AND DISPOSAL PROCEDURES

large spills.
Waste Disposal Method: Dispose according to Federal EPA procedures as outlined in the Resource Conservation Recovery act
(RCRA) and follow state and local guidelines. Triple rinse and puncture containers as required.

9. HANDLING AND STORAGE
Precautions: Store in a cool, dry place if possible. Separate from other pesticides, fertilizers, seed, feed, foodstuffs, and away from
drains, sewers, and water sources.
Other Precautions: Use only with adequate ventilation. Keep away from heat, sparks and flames. Keep container tightly closed.
Do not consume food, drink or tobacco in the areas where they may become contaminated with this material.
