FLASH POINT: Not Applicable
FLAMMABLE LIMITS (% BY VOL.): Not Applicable
AUTOIGNITION TEMP.: Not Available
DECOMPOSITION TEMP: Not Available
FIRE EXTINGUISHING MEDIA:
This material will not burn or burns with difficulty. Use an extinguishing
agent suitable for surrounding fires.
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.
Conduct fire fighting and rescue operations from upwind of the fire area.
Evacuate people downwind who may come in contact with smoke, fumes, or
contaminated surfaces. 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. Alert
medical personnel to be ready to treat for pesticide poisoning. Control
run-off water - if water enters a drainage system, advise the authorities
downstream.
Pesticide is attached to clay particles which will not burn but toxic fumes
may be released.

HEALTH HAZARD INFORMATION
---------------------------------------------------------------------------
TOXICITY DATA AND EFFECTS OF OVEREXPOSURE:
ACUTE TOXICITY DATA: The acute oral LD50 of this product in the male
albino rat is 11.7 mg/kg which indicates the material is highly toxic by
ingestion in single doses. Toxicity is primarily related to inhibition of
cholinesterase activity.
The acute dermal LD50 of this product in the male albino rabbit is 10.2
mg/kg which indicates the material is highly toxic by single skin
applications. Repeated exposure may inhibit cholinesterase activity.
Eye Contact: Terbufos (COUNTER) is absorbed through ocular exposure
producing systemic effects.
Inhalation Toxicity: Airborne terbufos (COUNTER) can be absorbed through
lungs to produce cholinesterase-inhibition.
The clinical signs of overexposure observed in animal studies are ataxia,
tremors, depression, diuresis, salivation and diarrhea.
CHRONIC TOXICITY DATA:
Mutagenicity:
No mutagenic activity was observed in COUNTER Tech by all test methods
used. These included Bacterial/Microsome Reverse Mutation (Ames) Test,
in vitro Chinese Hamster Ovary Cells/Hypoxanthine Guanine Phosphoribosyl
Transferase (HGPRT) Mutation Assay, Chromosome Aberrations in Chinese
Hamster Ovary Cells, Rat Hepatocyte Primary Culture/DNA Repair Test, and
Acute in vivo Cytogenetics Assay in Rats.
Teratogenicity:
No fetotoxic effects were found in any of the dose levels tested on rats,
rabbits, mallard duck and bobwhite quail. The reproductive studies in the
rabbit, mallard and bobwhite did show a small degree of maternal toxicity
with a no observable effect limit (NOEL) 0.4 mg/kg, 15ppm and 30ppm
respectively.
Carcinogenicity:
No oncogenic effects were observed at all dosage levels tested in rats and
mice.
Terbufos (the active ingredient in COUNTER) is not listed as a human
carcinogen by IARC, OSHA or NTP.
Note: All chronic toxicity testing is done on the technical material only.
There is no information available on the toxicity of the formulations
relative to that of the technical material.
EMERGENCY AND FIRST AID PROCEDURES:
CALL A PHYSICIAN AT ONCE IN ALL CASES OF SUSPECTED POISONING.
If swallowed: Drink one or two glasses of water and induce vomiting by
touching back of throat with finger. Repeat until vomit is clear. Do not
induce vomiting or give anything by mouth to an unconscious person. Get
medical attention.
If inhaled: Remove to fresh air. If victim is not breathing, give
artificial respiration, preferably mouth-to-mouth. If breathing is
difficult, give oxygen. Get medical attention.
If in eyes: Immediately flush eyes with plenty of water. Get medical
attention.
If on skin: Wash thoroughly with soap and water. Remove contaminated
clothing and shoes. Wash clothing and decontaminate shoes before reuse.
NOTES TO PHYSICIAN: Warning symptoms include weakness, headache, tightness
of chest, blurred vision, nonreactive pinpoint pupils, salivation,
sweating, nausea, vomiting, diarrhea, and abdominal cramps. Give atropine
intramuscularly or intravenously, depending on severity of poisoning, 2
to 4 mg. every 10 minutes until fully atropinized as shown by dilated
pupils, dry flushed skin and tachycardia. Twenty to 30 mg. or more may be
required during the first 24 hours. Never give opiates or phenothiazine
tranquilizers. Clear chest by postural drainage. Artificial respiration or
oxygen administration may be necessary. Observe patient continuously for at
least 48 hours. Allow no further exposure to any cholinesterase inhibitor
until cholinesterase regeneration has taken place as determined by blood
tests. Pralidoxime chloride (2-PAM: PROTOPAM chloride) may be effective as
an adjunct to atropine. Use according to label directions.
---------------------------------------------------------------------------
EXPOSURE CONTROL METHODS
---------------------------------------------------------------------------
During formulation of this product, provide adequate ventilation and
maintain the permissible exposure limit below 0.05 mg/m^3 or the use of a
NIOSH approved toxic dust respirator if necessary.
Wear freshly-laundered, long-sleeved work clothing daily. Wear rubber boots
or rubber shoe covering and gloves (rubber) and goggles while transferring
from package to equipment.
Rubber gloves should be washed with soap and water after each use. Do not
wear the same gloves for other work. Replace gloves frequently.
Administer a cholinesterase blood test program at workplace.
In case of contact, immediately remove contaminated clothing and wash skin
thoroughly with soap and water. Launder clothing before reuse. Wash
thoroughly with soap and water before eating or smoking. Shower at the end
of the work day and change clothing.
Wear a face mask or other respiratory equipment while emptying bags into
hopper. Pour downwind and allow as little free fall as possible while
emptying bags into equipment. DO NOT BREATHE THE DUST.

SPILL OR LEAK PROCEDURES
---------------------------------------------------------------------------
This material contains terbufos. The decontamination solution for this
material consists of 10% household bleach, 5% isopropyl alcohol, and 85%
water.
Wear appropriate protective clothing and personal protective equipment.
(See "Exposure Control".)
Keep away from drains, surface and ground water, and soil.
Shovel or sweep the spilled material into covered containers for proper
disposal. (See "Waste Disposal".) If possible, reuse the material for its
intended purpose.
Decontaminate the spill area and any tools or implements by rinsing several
times with the decontamination solution. Contain and absorb this rinsate
with inert absorbents and place into the same covered container as the
spilled material.
Spills to the soil can be shoveled directly into covered containers for
disposal. 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. Depending on local spill
reporting requirements and the amount released to the environment, it may
be necessary to notify the regulatory authorities.
