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, Foam, Dry Chemical, CO2.
Fire Fighting Instructions
Evacuate personnel to a safe area. Wear self-contained breathing
apparatus. Wear full protective equipment. Use 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.
----------------------------------------------------------------------

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Metsulfuron Methyl 60XP
Oral LD50: > 5000 mg/kg in rats
(Very low toxicity)
Skin LD50: > 2000 mg/kg in rabbits
(Slight to moderate toxicity)
Metsulfuron Methyl 60XP is a slight eye irritant, but is
not a skin irritant or skin sensitizer in animal tests.
Metsulfuron Methyl
Inhalation LC50, 4 hr: > 5.3 mg/L in rats
(Very low toxicity)
Single exposures of animals to Metsulfuron Methyl by
inhalation caused body weight loss and other nonspecific
effects.
Repeated applications of Metsulfuron Methyl to the skin of
rabbits caused skin irritation but no other changes were
observed.
Repeated oral doses of Metsulfuron Methyl produced decreased
body weight gain and decreased liver weights when compared
to the control group. Long term administration caused body
weight loss.
Animal testing indicates that Metsulfuron Methyl does not
have carcinogenic, developmental, or reproductive effects.
There is a report indicating that Metsulfuron Methyl
produced genetic damage in a mammalian cell culture test;
however, other tests with Metsulfuron Methyl in bacterial
and mammalian cell cultures and in animals did not produce
genetic damage. The weight of evidence suggests that
Metsulfuron Methyl does not cause genetic damage.
Chlorsulfuron XP
Oral LD50: > 5000 mg/kg in rats
(Very low toxicity)
Skin Absorption LD50: > 2000 mg/kg in rabbits
(Slightly to moderately toxic)
Chlorsulfuron XP 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
M0000643 DuPont Page 7
Material Safety Data Sheet
(TOXICOLOGICAL INFORMATION - Continued)
of a single dose of Chlorsulfuron include lung changes,
weakness and other nonspecific effects.
The effects in animals from repeated exposures by inhalation
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 resulted in decreased body weight gain and slight
hematological changes.
Animal testing indicates that Chlorsulfuron, the active
ingredient, did not show carcinogenic or reproductive
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.
