Fire/Explosion Hazard Like most organic powders or crystals, under severe dusting conditions this material may form explosive mixtures in air. Extinguishing Media Water Spray. Dry Chemical. Fire Fighting Instructions Wear self-contained breathing apparatus. Wear full protective equipment. Use water spray. Runoff from fire control may be a pollution hazard. If area is heavily exposed to fire and if conditions permit, let fire burn itself out since water may increase the area contaminated. Hazchem code 2Z 6. ACCIDENTAL RELEASE MEASURES Spill precautions Spill containment Spill clean-up 7. HANDLING AND STORAGE Use appropriate Personal Protective Equipment during clean up.(see Section 8) Dyke spill. Prevent liquid from entering the sewers, waterways, or low areas. Shovel or sweep up. DO NOT flush with water. Place material in a clean, dry container and cover for disposal. Wash contaminated areas with water and detergent. Prevent liquid from entering sewers, waterways or low areas. Soak up with sawdust, sand or other absorbent material. Shovel or sweep up. Never return to container for reuse. (See section 13 for disposal instructions.). Handling Storage Avoid skin and eye contact. Avoid inhaling the vapour, or spray mist. Wash thoroughly after handling. Wash clothing after use. Store in the closed, original container in a dry, well ventilated area, as cool as possible out of direct sunlight and under lock and key. Keep from contact with fertilisers, fungicides and seeds. Do not store with Classes 1, 2, 3.2, 4 or 5 substances. Stores containing more than 100 kg of this product, either alone or in aggregate with other hazardous substances are subject to requirement of an emergency management response plan, secondary containment and signage.

Do not consume food, drink or tobacco in the areas where they may become contaminated with this material. AEL (DuPont) 10mg/m3 (8 and 12 hr TWA) total dust. AEL (DuPont) 5mg/m3 (8 and 12 hr TWA) respirable dust. Avoid contact with eyes by wearing safety glasses or chemical splash goggles as needed. Where there is potential for airborne exposures in excess of applicable limits, wear NIOSH/MSHA approved pesticide respirator. Where there is potential for skin contact have available and wear as appropriate, impervious gloves, apron, pants, jacket, and overalls. 9.

(Rabbits): LD50 greater than 2,000 mg/kg. Slightly toxic Product was not a skin irritant to rabbits. Tests on guinea pigs indicate mild irritant but not a skin sensitise. (Rat) (active ingredient) LC50 greater than 5 mg/l (4-hour exposure). Moderately toxic. (Rats): LD50 greater than 5,000 mg/kg. Very low toxicity. DuPont (New Zealand) Limited Page 3 of 6

4 Chronic Effects Reproduction 2-year Rat Study Dietary concentrations were 0, 25, 250 or 2,500 ppm Chlorimuron-ethyl. This compound was not oncogenic at any dose. The no-observable-effect-level (NOEL) was 250 ppm based on transient anemia observed during the first year of the study and on slight body and organ weight changes. Study in Rats Dietary concentrations were 0, 25, 250 or 2,500 ppm for a 2-generation, 4-litter study. Reproduction and lactation performance was not affected at any dose. The NOEL for maternal and fetotoxicity was 250 ppm. This was based on reduced maternal and foetal body weights and a compromised nutritional state among offspring at the high dose. Teratology Studies Rats were dosed via incubation at 0, 30, 150 or 600 mg/kg/day. The NOEL for maternal and fetotoxicity was 30 mg/kg/day based on reduced food consumption and body weight gain Human Effects 12. ECOLOGICAL INFORMATION and increased frequency of foetal variations. There was a slight increase in the number of foetal malformations in the presence of overt maternal toxicity at the high dose. Although this was not statistically significant, it was considered to be a weak teratogenic response. In this study, Chlorimuron ethyl was not demonstrated to be a unique hazard. Rabbits were dosed via incubation at 0, 15, 60 or 300 mg/kg/day. There were no teratogenic effects at any dose. The NOELs for maternal and fetotoxicity were 60 and 15 mg/kg/day, respectively. These were based on reduced body weight gain and increased frequency of foetal variations due to retarded development. The foetal effects were only produced at maternally toxic doses; therefore, this product was not uniquely hazardous. Based on data from animal tests, prolonged ingestion of high doses of Chlorimuron ethyl may include abnormal liver function as detected by laboratory tests; or anemia. Otherwise no acceptable information is available to confidently predict the effects of excessive human exposure to this compound. Individuals with pre-existing diseases of the liver may have increased susceptibility to the toxicity of excessive exposures.
