HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Emergency Overview
CAUTION! Causes moderate eye irritation. Harmful if
absorbed through the skin. Avoid contact with skin,
eyes or clothing. Wash thoroughly with soap and water
after handling and before eating, drinking, chewing gum,
or using tobacco. Remove and wash contaminated clothing
before reuse.
Potential Health Effects
Based on animal data, repeated or excessive overexposure to
Chlorimuron Ethyl by ingestion may cause abnormal liver function
with altered enzyme levels in blood, or alterations in blood cell
counts and/or anemia.
Carcinogenicity Information
None of the components present in this material at concentrations
equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH
as a carcinogen.
----------------------------------------------------------------------
FIRST AID MEASURES
----------------------------------------------------------------------
First Aid
IF IN EYES: Hold open eye and rinse slowly and gently
with water for 15-20 minutes. Remove contact lenses,

minutes. Call a poison control center or doctor for
treatment advice.
IF INHALED: No specific intervention is indicated, as the
product is not likely to be hazardous by inhalation.
Consult a physician if necessary.
IF SWALLOWED: No specific intervention is indicated, as the
product is not likely to be hazardous by ingestion. Consult

FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Not a fire or explosion hazard.
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.
----------------------------------------------------------------------
ACCIDENTAL RELEASE MEASURES
----------------------------------------------------------------------
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)
sections before proceeding with clean-up. Use appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Initial Containment
Dike spill. Prevent material from entering sewers, waterways, or
low areas.
Spill Clean Up
Shovel or sweep up. Dispose of in an approved container.
For minor spills, leaks, etc., follow all precautions
indicated on the label and clean up immediately. Take
special care to avoid contamination of equipment and
facilities during clean up procedures and disposal of
wastes. In the event of a major spill, fire or other
emergency, call 1-800-441-3637 day or night.
Accidental Release Measures
If spill area is on ground near valuable plants or trees
remove top 2 inches of soil after initial cleanup

if pesticide gets inside. Then wash thoroughly and put on
clean clothing. Remove PPE immediately after handling this
product. Wash the outside of gloves before removing. As
soon as possible, wash thoroughly and change into clean
clothing.

in a cool, dry place. Keep out of reach of children.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
When handlers use closed systems, enclosed cabs or aircraft
in a manner that meets the requirements listed in the
Workers Protection Standard (WPS) for agricultural
pesticides [40 CFR part 170 Section 170.240(d)(4-6)], the
handler PPE requirements may be reduced or modified as
specified in the WPS.
Important: When reduced PPE is worn because a closed system
is being used, handlers must be provided all PPE specified
above for "Applicators and Other Handlers" and have such PPE
immediately available for use in an emergency, such as a
spill or equipment breakdown.
Personal Protective Equipment
Some materials that are chemical resistant to this product
are listed above. If you want more options, follow the
instructions for Category A on an EPA chemical resistance
category selection chart.
Applicators and other handlers must wear:
- Long-sleeved shirt and long pants.
- Chemical Resistant Gloves made of any waterproof
material such as polyethylene or polyvinyl chloride.
M0000695 DuPont Page 5
Material Safety Data Sheet
(EXPOSURE CONTROLS/PERSONAL PROTECTION - Continued)
- Shoes plus socks.
Follow manufacturer鈥檚 instructions for cleaning/maintaining
PPE. If no such instructions for washables, use detergent
and hot water. Keep and wash PPE separately from other
laundry.
PPE required for early entry into treated areas that is
permitted under the Worker Protection Standard and that
involves contact with anything that has been treated, such
as plants, soil, or water, is:
- Coveralls.
- Chemical Resistant Gloves made of any waterproof
material such as polyethylene or polyvinyl chloride.
- Shoes plus socks.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Oral LD50: > 5000 mg/kg in rats
Skin Absorption LD50: > 2000 mg/kg in rabbits
Inhalation 4-hour LC50: > 5 mg/L in rats
Based on data from components, this product is a mild eye
irritant, but is not a skin irritant or a skin sensitizer in
animals.
CHLORIMURON ETHYL
Repeated applications of Chlorimuron Ethyl to the skin
of rabbits for 21 days at doses up to and including the
limit dose resulted in no significant toxicological effects.
Repeated and long-term ingestion of Chlorimuron Ethyl by
rats, mice, and dogs caused liver effects, anemia, altered
clinical chemistry, and/or decreased body weight at higher
exposure levels. In rats and mice, Chlorimuron Ethyl has
not caused carcinogenicity.
Exposure of pregnant rabbits caused developmental delays in
the fetus at maternally toxic doses. However, studies in
rats produced no evidence of developmental toxicity.
Reproductive data in rats show nutritional and organ effects
in offspring only at levels which produce other toxic
effects in the adult animal. There were no effects on
fertility or lactation indices in rats. Tests have shown
that Chlorimuron Ethyl does not cause genetic damage in
bacterial or mammalian cell cultures, or in animals.
THIFENSULFURON METHYL
Repeated ingestion exposures to Thifensulfuron Methyl caused
decreased body weight and organ weight changes, and some
blood chemistry changes, including increased blood urea
M0000695 DuPont Page 7
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
nitrogen and decreased protein and globulins. Long-term
exposures caused an increase in liver weights, decreased
body weight gain, and a decreased level of sodium in the
blood when compared to the control group.
No carcinogenic effects were observed in animal tests with
Thifensulfuron Methyl. Animal data show developmental
effects only at exposure levels producing toxic effects in
the adult animal. Tests in animals demonstrate no
reproductive toxicity. Thifensulfuron Methyl does not
produce genetic damage in bacterial or mammalian cell
cultures or animals.
