HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Emergency Overview
DANGER! CAUSES EYE DAMAGE. Corrosive, causes irreversible
eye damage. Harmful if swallowed. Do not get in eyes or on
clothing. Wash thoroughly with soap and water after
handling.
# Potential Health Effects
Based on animal data, eye contact with Velpar L may cause
corneal opacity or clouding of the eye.
Based on animal data, skin contact with Hexazinone may cause
skin irritation with discomfort or rash.
Based on data from animal testing, ingestion of large
amounts of Hexazinone may cause effects on the liver.
Significant skin permeation and systemic toxicity after
contact appears unlikely.
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 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 eye. Call
a poison control center or doctor for treatment advice.
IF ON SKIN OR CLOTHING: 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 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 the poison control center or doctor. Do
not give anything by mouth to an unconscious person.
INHALATION: No specific intervention is indicated, as the
compound is not likely to be hazardous by inhalation.
Consult a physician if necessary.

TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
VELPAR L
Oral LD50: 4120 mg/kg in rats
Dermal LD50: > 5000 mg/kg in rabbits
Inhalation 4 hour LC50: > 5.0 mg/L in rats
VELPAR L is corrosive to the eye. It was slightly
irritating to the skin, but is not a skin sensitizer in
animals.
HEXAZINONE
Repeated skin applications indicated no irritation or
systemic activity.
Repeated dosing by ingestion of excessive dietary levels of
Hexazinone resulted in weight loss, alterations in liver
weights alterations in blood chemical measurements, and
alterations in enzyme activities. No evidence of
pathological organ damage was observed. Long-term dosing
produced decreased weight gain, alterations in hematology,
clinical chemistry, and blood enzyme levels, increased liver
weights in some species, and pathological liver changes.
Animal data showed that chronic, excessive dietary exposure
to Hexazinone produced a slight, equivocal increase in liver
tumors in female mice.
Animal data show developmental effects only at exposure
levels producing other toxic effects in the adult animal.
Animal testing indicates Hexazinone does not have
reproductive effects. The weight of evidence from a battery
of cell culture and laboratory animal tests indicates
Hexazinone does not cause genetic toxicity.

DISPOSAL CONSIDERATIONS
----------------------------------------------------------------------
Waste Disposal
Treatment, storage, transportation, and disposal must be in
accordance with applicable Federal, State/Provincial, and Local
regulations.
Do not contaminate water, food or feed by disposal. Waste
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 disposing of
equipment wastewaters.
The active ingredient, hexazinone, in this product is known
to leach through soil into ground water under certain
conditions as a result of agricultural use. Use of this
chemical in areas where soils are permeable, particularly
where the water table is shallow, may result in ground-water
contamination.
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 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 the State and
local authorities.
Container Refilling and Disposal (For Containers up to
250 gal): This is a refillable container. If the container
is to be refilled, do not rinse with any material or
introduce any pesticide other than VELPAR L. Reseal and
return the container to any authorized DuPont refilling
facility. If the container is not to be refilled, triple
rinse (or equivalent) and offer for recycling or
reconditioning, or puncture and dispose of in a sanitary
landfill, or by incineration, or by open burning, if
allowed by state and local authorities. If burned, keep
out of smoke.
