NOTE TO PHYSICIAN: Endosulfan is a central nervous system stimulant absorbable by mouth,
inhalation, or through contact with skin. It may cause convulsions. There is no specific antidote.
Diazepam I.V. is the drug of choice. Barbituric acid derivatives such as Phenobarbital may be used
additionally. A neuromuscular blocking agent may be used if convulsions persist. This type of drug may
be used only if complete control of respiration can be maintained. Epinephrine derivatives are absolutely
contraindicated. This formula contains petroleum hydrocarbons (xylene range aromatic solvent). Care
should be taken to prevent aspiration because of the possibility of chemical pneumonia or pulmonary
edema due to the organic solvent in the formulation.
5. FIRE FIGHTING MEASURES
o
FLASH POINT AND METHOD: 62.2 C (TCC)
EXTINGUISHING MEDIA: Foam, CO2 or dry chemical. Soft stream water fog only if necessary. Contain
all runoff.
FIRE/EXPLOSION HAZARDS: Moderately combustible. When heated above the flash point, this material
releases vapors which, when mixed with air, can burn or be explosive.
FIRE FIGHTING PROCEDURES: Isolate fire area. Evacuate downwind. Wear full protective clothing and
self-contained breathing apparatus. Do not breathe smoke, gases, or vapors generated.
HAZARDOUS DECOMPOSITION PRODUCTS: Carbon monoxide, carbon dioxide, hydrogen chloride,
and oxides of sulfur.
6. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES: 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 lakes, streams, ponds, and sewer drains. Dike to confine spill and absorb with a non-
combustible absorbent such as clay, sand, or soil. Vacuum, shovel, or pump waste into a drum and label
contents for disposal.
To clean and neutralize spill area, tools, and equipment, wash with a suitable solution of caustic or 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
GENERAL PROCEDURES: Store in a cool, dry, well-ventilated place. Do not use or store near heat,
open flame, or hot surfaces. Keep out of reach of children and animals. Store in original containers only.

DERMAL LD50: 256 mg/kg (rabbit)
ORAL LD50: 44.9 mg/kg (rat)
INHALATION LC50: 22 mg/L/4 hr. (rat)
ACUTE EFFECTS FROM OVEREXPOSURE: This product is highly toxic if swallowed, inhaled, or
absorbed through the skin. It is moderately irritating to the eyes and skin. Signs of toxicity in laboratory
animals included tremors, convulsions, decreased locomotion, chromorhinorrhea, and oral discharge.
Inhalation of aromatic hydrocarbon vapors may cause dizziness, disturbances i vision, drowsiness,
n
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 the formulation. 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 non-mutagenic
in a battery of tests. Chronic exposure to aromatic hydrocarbons may cause headaches, dizziness, loss
of sensation or feelings (such as numbness), and liver and kidney damage. Inhalation of xylene vapors at
high doses has also resulted in an increased incidence of malformations and decreases in fetal weight in
laboratory animals.
12. ECOLOGICAL INFORMATION
Unless otherwise indicated, the data presented below are based on the active ingredient.

ENVIRONMENTAL DATA: 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 a- and ?isomers degrade at
different rates, with the ?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.
ECOTOXICOLOGICAL INFORMATION: Endosulfan is considered highly toxic to fish with LC50 values of
1.0 to 10.0 礸/L. Crustaceans and mollusks are less sensitive with LC50 values of 10 to 1600 礸/L.
Endosulfan is slightly toxic to birds and oral LD50 values range from 200 to 1000 mg/kg.
13. DISPOSAL CONSIDERATIONS
DISPOSAL METHOD: Open dumping or burning of this material 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 environmental laws, rules, standards, and
regulations. However, because acceptable methods of disposal may vary by location and regulatory
requirements may change, the appropriate agencies should be contacted prior to disposal.
EMPTY CONTAINER: Non-returnable containers that 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.
