HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Emergency Overview
Harmful if swallowed, inhaled, or absorbed through skin.
Causes moderate eye irritation. Avoid breathing dust, vapor
or spray mist. Avoid contact with skin, eye or clothing.
In case of contact with eyes, immediately flush with plenty
of water. Get medical attention if irritation persists.
Potential Health Effects
Based on animal data, eye contact may cause eye irritation
with discomfort, tearing, or blurring of vision.
Based on animal data, repeated or excessive overexposure 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 SWALLOWED: Call poison control center or doctor
immediately for treatment advice. Have person sip a glass
of water if able to swallow. Do not induce vomiting unless
told to do so by a poison control center or doctor.
IF ON SKIN: Take off contaminated clothing. Rinse skin
immediately with plenty of water for 15-20 minutes. Call a
poison control center or doctor for treatment advice.
IF IN EYES: Hold eye open and rinse slowly and gently with
water for 15-20 minutes. Remove contact lenses, if present,
after the first 5 minutes, then continue rinsing. Call a
poison control center or doctor for treatment advice.
IF INHALED: Move person to fresh air. If person is not
breathing, call 911 or an ambulance, then give artificial
respiration, preferably by mouth-to-mouth, if possible.
Call a poison control center or doctor for further treatment
advice.
Have the product container or label with you when calling a
poison control center or doctor. For medical emergencies

FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Not a fire or 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. Keep personnel removed and upwind of fire. Cool
tank/container with water spray. Runoff from fire control may be
a pollution hazard.
If area is exposed to fire and conditions permit, let fire burn
itself out. Burning chemicals may produce by-products more toxic
than the original material. If product is on fire, wear
self-contained breathing apparatus and full protective equipment.
Use water spray. Control runoff.
----------------------------------------------------------------------
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.
Emergency Response - Chemical resistant coveralls, waterproof
gloves, waterproof boots and face/eye protection. If dusting
occurs, use NIOSH approved respirator protection.
Initial Containment
Dike spill. Prevent material from entering sewers, waterways, or
low areas. Follow applicable Federal, State/Provincial and Local
laws/ regulations.
Spill Clean Up
Shovel or sweep up.
Accidental Release Measures
If spill area is on ground near valuable plants or trees,
remove top 2 inches of soil after initial cleanup.

HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
USERS SHOULD: Wash thoroughly with soap and water after
handling and before eating, drinking, chewing gum, using
tobacco or using the toilet. Remove clothing immediately
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.
Handling (Physical Aspects)
Avoid dust generation.
Storage
Store product in original container only. Do not
contaminate water, other pesticides, fertilizer, food or
feed in storage. Store in a cool, dry place.
----------------------------------------------------------------------
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 Worker Protection Standard (WPS) for agricultural
pesticides [40 CFR part 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 of the material that are chemical-resistant to this
product are listed below. If you want more options, follow
the instructions for category A on an EPA chemical-resistant
category selection chart.
Applicators and other handlers must wear:
Long-sleeved shirt and long pants.
Chemical resistant gloves made of any water proof
material such as polyethylene or polyvinylchloride.
Shoes plus socks.
Discard clothing and other absorbent material that have
M0000632 DuPont Page 5
Material Safety Data Sheet
(EXPOSURE CONTROLS/PERSONAL PROTECTION - Continued)
been drenched or heavily contaminated with the product.
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 water proof
material such as polyethylene or polyvinylchloride.
Shoes plus socks.

# Animal Data
CANOPY
Oral LD50 : 1282 mg/kg in rats
Dermal LD50 : > 5,000 mg/kg in rats
4-Hour Inhalation LC50: > 5.3 mg/L in rats
Canopy is a mild to moderate eye irritant, a slight skin
irritant, but is not a skin sensitizer in animals.
METRIBUZIN
Repeated exposures to high doses produced decreased growth
rate, liver and thyroid enlargement, and kidney damage.
NOEL (No-observed-effect-level) was 100 ppm in long-term
feeding studies in dogs and rats.
Animal testing indicates that Metribuzin does not have
carcinogenic, developmental, or reproductive effects.
Metribuzin did not produce genetic damage in bacterial or
mammalian cell cultures or in tests in animals. It did not
produce heritable genetic damage.
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, slight to mild
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 rats and rabbits caused growth
retardation in the fetus at maternally toxic doses.
Developmental toxicity was also observed in fetuses from
rats exposed to maternally toxic doses. 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
M0000632 DuPont Page 7

genetic damage in bacterial or mammalian cell cultures, or
in animals.
