FIRE CONTROL TACTICS:
Wear self-contained, positive pressure breathing apparatus
and full fire fighting protective clothing.
Keep unnecessary people away. Use as little water as
possible. Dike area of fire to prevent pesticide run-off.
Use spray or fog - solid stream may cause spreading. Do
not decontaminate personnel or equipment, or handle broken
packages or containers without protective equipment as
specified in the Exposure Control Section. Decontaminate
emergency personnel with soap and water before leaving the
fire area.
Avoid breathing dusts, vapors and fumes from burning
materials. Control run-off water - if water enters a
drainage system, advise the authorities downstream.
This product is a Class III combustible liquid, based on
its flash points. Storage areas must conform to NFPA 30
and NFPA 70, or local standards, whichever is more
stringent.

HEALTH HAZARD TOXICITY DATA AND
INFORMATION EFFECTS OF OVEREXPOSURE:
ACUTE TOXICITY DATA:
The acute oral LD<50> in rats for the combined sexes was
shown to be 3956 mg/kg b.w., indicating that the material
is slight to moderately toxic by ingestion in single
doses.
The acute dermal LD<50> in rabbits was shown to be greater
than 2200 mg/kg b.w. (highest dose tested), indicating
that the product is only slightly toxic by dermal
MSDS SHEET NO. AG09129-3 PAGE 3
_______________________________________________________________________________
application in a single dose.
The material was determined to be mildly irritating to
rabbit skin and eyes and shown to be a non-skin sensitizer
in appropriate guinea pig studies.
Acute inhalation studies in rats demonstrated that the
LC<50> was greater than 5.35 mg/L (actual) of air over a 4
hour exposure period.
CHRONIC TOXICITY DATA:
This material as formulated has not been tested for
chronic toxicity, however, the chronic toxicity of
Pendimethalin is as follows:
Mutagenicity:
In an evaluation of data from a battery of six
genotoxicity tests, pendimethalin was judged to be
nongenotoxic.
Teratogenicity:
No teratogenic or fetotoxic effects were observed in rats
or rabbits.
Reproduction:
No reproductive effects were observed in a
three-generation reproduction study conducted in rats.
Oncogenicity:
No oncogenic effects were observed at all dosage levels
tested in the lifetime (18 months) mouse study. The
highest dose tested was 5000 ppm in the diet.
A marked depression in body weight gain, and statistically
significant increase in benign thyroid proliferative
lesions were observed at the highest dose tested (5000
ppm) in the lifetime (24 months) rat study.
EMERGENCY AND FIRST AID PROCEDURES:
: Do not induce vomiting. Get medical
attention.
: Flush eyes with large amounts of tap water.
Get medical attention if irritation persists.
: Wash skin with plenty of soap and water.
Get medical attention if irritation persists.
: Remove subject to fresh air.

NOTES TO PHYSICIAN:
Because of increased risk of chemical pneumonia or
pulmonary edema caused by aspiration of aromatic
hydrocarbons into the lungs, vomiting should be induced
only under professional supervision.
Pendimethalin is a strongly orange-red colored compound -
virtually an aniline dye. Cases have been described of
orange-yellow coloration of the urine following heavy
exposure of workers to the dust of this compound. Despite
its structure as both a nitro-compound and aromatic amine,
exposure to pendimethalin is NOT associated with
methemoglobinemia.
_______________________________________________________________________________
EXPOSURE During formulation of this product, the following good
CONTROL METHODS industrial hygiene practice is recommended:
Provide adequate local ventilation and maintain a
Permissible Exposure Limit (PEL) below the level
recommended for the various components of the product. If
vapor levels exceed the PEL, an approved pesticide
respirator should be worn until engineering control are
achieved.
Chemical goggles or some other form of eye protection
should be worn to prevent exposure to the eyes. Wear
rubber gloves when handling this material. An apron or
impermeable covering should be worn where splashing could
occur.
Wash thoroughly with soap and water after handling.
Remove contaminated clothing and wash before reuse.
For end-users, please refer to the product label for
personal protective clothing/equipment.
_______________________________________________________________________________
SPILL OR LEAK Wear appropriate protective clothing and personal
PROCEDURES protective equipment. (See "Exposure Control".)
Keep away from drains, surface and ground water, and soil.
Dike spill area to prevent spill from spreading. Absorb
the spilled material with an inert absorbent such as
granular clay or sawdust. Shovel or sweep the absorbed
spill into covered containers for proper disposal. (See
"Waste Disposal".)
Rinse the spill area and any tools or implements several
times with soapy water. Contain and absorb this rinsate
with inert absorbents and place into the same disposal
container as the spilled material.
Small spills to the soil can be shoveled directly into
covered containers for disposal. In the event of a large
spill, contact American Cyanamid for guidance on available
MSDS SHEET NO. AG09129-3 PAGE 5
_______________________________________________________________________________
clean-up options. Depending on the amount released to the
environment, it may be necessary to notify the regulatory
authorities.
If the spill occurred to a body of water, immediately
notify the appropriate authorities downstream of the spill
so that they can decide what if any further action is
needed.
____________________________________________________________________________
WASTE DISPOSAL: To avoid disposal, all attempts should be
made to use this product completely, in
accordance with its registered use. If
this is not possible, handle with care,
and dispose in a safe manner.
Follow all applicable community, national
or regional regulations regarding waste
management methods.
Empty containers or liners may retain some
product residues. DO NOT REUSE. Triple
rinse the container or liner thoroughly
and render it unusable by crushing or
puncturing. Dispose of both the container
and the rinsate in a safe manner.
It is the ultimate responsibility of the
waste generator to determine at the time
of disposal whether this product and/or
"empty" container residue meets any
hazardous waste criteria.
_______________________________________________________________________________
SPECIAL HANDLING AND STORAGE:
PRECAUTIONS Do not store below 40F. Do not contaminate water, food
or feed by storage or disposal. Store in a secure, dry,
well-ventilated separate area; away from children,
livestock and food products.
Not for use or storage in or around the home.
Keep away from sources of ignition and protect from
exposure to fire and heat.
Segregate from oxidizers and incompatible materials listed
in the Reactivity Data Section.
This material is a Class III combustible liquid, based on
its flash points. Storage areas must conform to NFPA 30
and NFPA 70, or local standards, whichever is more
stringent.
