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
Wear self-contained breathing apparatus. Wear full protective
equipment. 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.

gloves, waterproof boots and face/eye protection. If dusting
occurs, use NIOSH approved respirator protection.
Initial Containment
Follow applicable Federal, State/Provincial and Local laws/
regulations.
Prevent material from entering sewers, waterways, or low areas.
Spill Clean Up
Shovel or sweep up.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
DuPont Express Herbicide (with TotalSol soluble granules):
Oral LD50: > 5000 mg/kg in rats
Skin absorption LD50: > 5000 mg/kg in rats
Inhalation 4 hour LC50: > 5.0 mg/L in rats
DuPont Express Herbicide (with TotalSol soluble granules) is
a moderate skin sensitizer, but is not an eye or skin
irritant in animals.
TRIBENURON METHYL:
The effects in animals from a single ingestion exposure to
Tribenuron Methyl include severe weight loss and decreased
food consumption. Repeated ingestion doses caused body
weight loss, increased liver and thyroid/parathyroid
weights, altered clinical chemical parameters, but no
significant gross or microscopic treatment related effects
were noted. Long-term dosing caused body weight loss,
alteration in clinical chemical parameters, and testicular
atrophy (considered to be biologically insignificant).
Tribenuron Methyl produced an increased incidence of mammary

(TOXICOLOGICAL INFORMATION - Continued)
tumors in female rats at dose levels also producing other
significant effects. Developmental effects occurred in the
rat, but only at a dose also toxic to the dam. No
reproductive effects were observed in rats. Tribenuron
Methyl did not produce genetic damage in bacterial or
mammalian cell cultures or in animals.

DISPOSAL CONSIDERATIONS
----------------------------------------------------------------------
Waste Disposal
Do not contaminate water, food, or feed by disposal. Wastes
resulting from the use of this product may be disposed of on
site or at an approved waste disposal facility.
ENVIRONMENTAL HAZARDS
Do not apply directly to water, or to areas where surface
water is present, or to intertidal areas below the mean high
water mark. Do not contaminate water when cleaning
equipment or disposing of equipment washwaters.
Container Disposal
For Plastic Containers: Triple rinse (or equivalent). Then
offer for recycling or reconditioning, or puncture and
dispose of in a sanitary landfill, or incineration, or, if
allowed by State and local authorities, by burning. If
burned, stay out of smoke.
For Fiber Sacks: Completely empty fiber sack by shaking and
tapping sides and bottom to loosen clinging particles. Empty
residue into manufacturing or application equipment. Then
dispose of sack in a sanitary landfill or by incineration if
allowed by State and local authorities.
For Fiber Drums with Liners: Completely empty liner by
shaking and tapping sides and bottom to loosen clinging
M0000679 DuPont Page 7
Material Safety Data Sheet
(DISPOSAL CONSIDERATIONS - Continued)
particles. Empty residue into application equipment. Then
dispose of liner in a sanitary landfill or by incineration
if allowed by State and local authorities. If drum is
contaminated and cannot be reused, dispose of in the same
manner.
For Bags Containing Water-Soluble Packets: Do not reuse the
outer box or the resealable plastic bag. When all water-
soluble packets are used, the outer packaging should be
clean and may be disposed of in a sanitary landfill or by
incineration, or if allowed by State and local authorities,
by open burning. If burned, stay out of smoke. If the
resealable plastic bag contacts the formulated product in
any way, the bag must be triple rinsed with clean water.
Add the rinsate to the spray tank and dispose of the outer
wrap as described above.
For Metal Containers (non aerosol): Triple rinse (or
equivalent) the container. Then offer for recycling or
reconditioning, or puncture and dispose of in a
sanitary landfill, or by other procedures approved by
State and local authorities.
