FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Flammable limits in Air, % by Volume
LEL : 0.092 g/L
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

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.

TOXICOLOGICAL INFORMATION

Animal Data
Oust XP
Inhalation 4 hour LC50: > 5.3 mg/L in rats
(Very low toxicity by inhalation)
Skin absorption LD50: > 5000 mg/kg in rabbits
(Slightly to moderately toxic by contact)
Oral LD50: > 5000 mg/kg in rats
(Very low toxicity by ingestion)
M0000620 DuPont Page 6
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
Oust XP is a slight to mild skin irritant, and a mild eye
irritant, but is not a skin sensitizer in animals.
Single inhalation exposure with Oust XP (Sulfometuron Methyl 75%)
in rats caused slight to moderate body weight loss, nasal and
ocular discharge, and other nonspecific effects.
Single high oral doses of Oust XP (Sulfometuron Methyl 75%)
produced no clinical signs of toxicity and no lesions were
observed during pathological examination of tissue.
Repeated oral studies with the active ingredient, Sulfometuron
Methyl, caused decreased body weight gain, liver changes, red
blood cell hemolysis, and altered white blood cell counts.
Long-term exposure caused mild hemolytic anemia, decreased body
weight, alteration of clinical chemical parameters, and changes in
the bile duct.
Animal testing indicates that the active ingredient, Sulfometuron
Methyl, does not have carcinogenic effects. In a two generation
rat reproduction study with the active ingredient, Sulfometuron
Methyl, decreased numbers of pups were observed at the 5000 ppm
level, a dose that was also maternally toxic. No reproductive
effects were observed at 500 ppm.
Sulfometuron methyl did not produce developmental toxicity when
tested in animals. Sulfometuron methyl did not produce genetic
damage in bacterial or mammalian cell cultures.
Telar DF Herbicide
Oral LD50: > 2000 mg/kg in rats
Skin Absorption LD50: > 5000 mg/kg in rats
(Slightly toxic)
Telar DF Herbicide is a mild reversible skin irritant, and a very
mild eye irritant, and is not a skin sensitizer in animals.
Chlorsulfuron
Inhalation 4 hour LC50: > 5.5 mg/L in rats
(Very low toxicity by inhalation)
Toxicity described in animals from the oral administration of a
single dose of Chlorsulfuron include lung changes, weakness and
other nonspecific effects.
The effects in animals from repeated inhalation exposures to
Chlorsulfuron include decreased weight gain, reversible kidney and
spleen effects, and bone marrow changes.
Repeated oral dosing caused decreased weight gain, and
hematological and clinical chemical changes. Long-term dosing
(500 ppm) resulted in decreased body weight gain, and slight
hematological changes.
M0000620 DuPont Page 7
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
Animal testing indicates that Chlorsulfuron, the active
ingredient, did not show reproductive or carcinogenic effects.
Developmental toxicity has been observed but only at maternally
toxic dose levels.
Chlorsulfuron did not produce genetic damage in bacterial or
mammalian cell cultures. It did not produce heritable genetic
damage.
