3. Hazards Identification
---------------------------------------------------------------------------
Emergency Overview:
Amber liquid with an aromatic hydrocarbon odor.
Moderately combustible. May support combustion if heated above the
product's flash point (40C/103F).
Thermal decomposition and burning may form toxic by-products.
For large exposures or fire, wear personal protective equipment.
Highly toxic to fish and aquatic organisms. Keep out of drains and water
courses.
High oral toxicity, and moderate inhalation and dermal toxicity.
Potential Health Effects: Effects from overexposure result from either
swallowing, breathing, or absorption through the skin. Symptoms of
overexposure include headache, weakness, abdominal cramps, nausea,
excessive salivation, perspiration, blurred vision, tearing, pin-point
pupils, convulsions, tremor, and coma.
Medical Conditions Aggravated by Exposure: None presently known.
---------------------------------------------------------------------------
4. First Aid Measures
---------------------------------------------------------------------------
Eyes: Flush with water for at least 15 minutes. If irritation occurs and
persists, obtain medical attention.
Skin: Wash with plenty of soap and water. Get medical attention if
irritation occurs and persists.
Inhalation: Remove to fresh air. If breathing difficulty or discomfort
occurs and persists, contact a medical doctor.
Ingestion: Rinse mouth with water. Dilute by giving 1 or 2 glasses of
water. Do not induce vomiting. Never give anything by mouth to an
unconscious person. See a medical doctor immediately.
Note to Medical Doctor: Thiodan Cottonseed Oil is highly toxic if swallowed
and moderately toxic if inhaled or absorbed through the skin. It is
minimally irritating to the eyes and skin. Endosulfan is a central nervous
system stimulant, absorbable through oral, inhalation, or dermal routes. It
may cause convulsions. Central nervous system stimulation can be controlled
with diazepam (i.v.) or barbituric acid derivatives. Epinephrine is
contraindicated due to cardiac muscle stimulation. This product contains
light aromatic hydrocarbons that can produce severe pneumonitis or fatal
pulmonary edema if aspirated. Consideration should be given to gastric
lavage with an endotracheal tube in place. Treatment is otherwise
controlled removal of exposure followed by symptomatic and supportive care.
---------------------------------------------------------------------------
5. Fire Fighting Measures
---------------------------------------------------------------------------
Flash Point: 40C (103F) (CC)
Extinguishing Media: Foam, CO2, or dry chemical. Soft stream water fog only
if necessary. Contain all runoff.
Degree of Fire/Explosion Hazard: Moderately combustible. When heated above
the flash point, this material released vapors which, when mixed with air,
can burn or be explosive.
Special Fire Fighting Procedures: Isolate fire area. Evacuate downwind.
Wear full protective clothing and self-contained breathing apparatus. Do
not breathe smoke, gases, or vapor generated.
Hazardous Decomposition Products: Sulfur dioxide, hydrogen chloride, carbon
dioxide, carbon monoxide, and hydrochloric acid.
---------------------------------------------------------------------------
6. Accidental Release Measures
---------------------------------------------------------------------------
Isolate and post spill area. Wear protective clothing and personal
protective equipment as prescribed in Section 8, "Exposure
Controls/Personal Protection." Keep unprotected persons and animals out of
the area.
Keep material out of streams and sewers. Dike to confine spill and absorb
with an absorbent such as clay, sand, or soil. Vacuum, shovel, or pump
waste into a drum and label contents.
To clean and neutralize spill area, tools, and equipment, wash with a
solution of caustic/soda ash and an appropriate alcohol (i.e., methanol,
ethanol, or isopropanol). Follow this by washing with a strong soap and
water solution. Absorb, as above, any excess liquid and add to the drums of
waste already collected. Repeat if necessary. Dispose of drummed waste
according to the method outlined in Section 13, "Disposal Considerations."
---------------------------------------------------------------------------
7. Handling and Storage
---------------------------------------------------------------------------
Store in a cool, dry, well-ventilated place. Do not use or store near heat,
open flame, or hot surfaces. Store in original containers only. Keep out
of reach of children and animals. Do not contaminate other pesticides,
fertilizers, water, food, or feed by storage or disposal.
---------------------------------------------------------------------------
8. Exposure Controls/Personal Protection
---------------------------------------------------------------------------
Personal protective recommendations for mixing or applying this product are
prescribed on the product label. Information stated below provides useful,
additional guidance for individuals whose use or handling of this product
is not guided by the product label.
Ventilation: Use local exhaust at all process locations where vapor or mist
may be emitted. Ventilate all transport vehicles prior to unloading.
Work Clothing: Depending upon concentrations encountered, wear coveralls or
long-sleeved uniform and head covering. For larger exposures as in the case
of spills, wear full body cover barrier suit, such as a PVC rain suit.
Leather items -- such as shoes, belts, and watchbands -- that become
contaminated should be removed and destroyed. Launder all work clothing
before reuse (separately from household laundry).
Eye Protection: For splash, mist, or spray exposure, wear chemical
protective goggles or a face shield.
Respiratory Protection: For splash, mist, or spray exposure, wear, as a
minimum, a properly fitted half-face or full-face air-purifying respirator
which is approved for pesticides (U.S. NIOSH/MSHA, EU CEN, or comparable
certification organization). Respirator use and selection must be based on
airborne concentrations.
Gloves: Wear chemical protective gloves made of materials such as rubber,
nitrile, or PVC. Thoroughly wash the outside of gloves with soap and water
prior to removal. Inspect regularly for leaks.
Personal Hygiene: Clean water should be available for washing in case of
eye or skin contamination. Wash skin prior to eating, drinking, or using
tobacco. Shower at the end of the workday.

11. Toxicological Information
---------------------------------------------------------------------------
Rat Acute Oral: LD50 = 40.7 mg/kg
Rabbit Acute Dermal: LD50 > 930 mg/kg
Rat Acute Inhalation: LC50 = 0.4 mg/L/4hr
Acute Effects From Overexposure: Thiodan Cottonseed Oil is highly toxic
if swallowed and moderately toxic if inhaled or absorbed through the
skin. It is minimally irritating to the eyes and skin. Signs of toxicity
in laboratory animals included tremors, clonic convulsions, decreased
locomotion, and oral discharge. Inhalation of aromatic hydrocarbon vapors
may cause dizziness, disturbances in vision, drowsiness, respiratory
irritation, and eye, skin, and mucous membrane irritation. Vomiting after
ingestion of this product may cause aspiration of aromatic hydrocarbons
into the lungs, which may result in fatal pulmonary edema.
Chronic Effects From Overexposure: No data available for Thiodan Cottonseed
Oil. In chronic studies with laboratory animals, endosulfan showed no
evidence of carcinogenicity. Endosulfan caused toxic nephropathy in
rat chronic feeding studies. In a two-generation reproduction study
with laboratory animals, endosulfan caused decreased litter weights at
the highest dose. Endosulfan was nonmutagenic in a battery of tests.
Chronic exposure to aromatic hydrocarbons may cause headaches, dizziness,
loss of sensations or feelings (such as numbness), and liver and kidney
damage. Inhalation of xylene vapors at high doses have also resulted in
an increased incidence of malformations and decreased fetal weight in
laboratory animals. Damage from xylene vapors may be potentiated by
alcohol.
Carcinogenicity:
IARC: No
NTP: No
Other (OSHA): No
---------------------------------------------------------------------------
12. Environmental Information
---------------------------------------------------------------------------
The information presented below is for the active ingredient, endosulfan.
Physical/Environmental Properties: In natural waters, endosulfan is more
readily degraded at pH 7 (half-life = 5 weeks) than at pH 5.5 (half-life =
5 months). The half-life in soils varies with soil type and environmental
conditions, with 120 days being average under agricultural conditions.
The alpha - and beta -isomers degrade at different rates, with the beta
-isomer being more persistent. Endosulfan has a slight potential for
movement in soils, however, the potential is decreased with increasing
organic matter content of the soil. The bioconcentration factor for
endosulfan varies by species and length of exposure, but is generally less
than 100.
Environmental Toxicology: Endosulfan is considered highly toxic to fish
with LC50 values of 1.0 to 10.0 mu g/L. Crustaceans and mollusks are less
sensitive with LC50 values of 10 to 1600 mu g/L. Endosulfan is slightly
toxic to birds, and oral LD50 values range from 200 to 1000 mg/kg.
---------------------------------------------------------------------------
13. Disposal Considerations
---------------------------------------------------------------------------
Open dumping or burning of this pesticide or its packaging is prohibited.
If spilled material cannot be disposed of by use according to label
instructions, an acceptable method of disposal is to incinerate in
accordance with local, state, and national laws and regulations. However,
because acceptable methods of disposal may vary by location and regulatory
requirements may change, the appropriate regulatory agencies should be
contacted prior to disposal.
Nonreturnable containers which held this material should be cleaned, prior
to disposal, by triple-rinsing. Containers which held this material may
be cleaned by being triple-rinsed and recycled, with the rinsate being
incinerated. Do not cut or weld metal containers. Vapors that form may
create an explosion hazard.
