3. Hazards Identification
Fire: Combustible under specific conditions. Liquid formulations containing
organic solvents may be flammable. Gives off irritating or toxic fumes (or
gases) in a fire.
Atrazine can affect when breathed in and by passing through the skin. It
should be handled as a carcinogen--with extreme caution. Contact may
irritate the eyes and skin.
Atrazine may cause a skin allergy. If allergy develops, very low future
exposures can cause itching and a skin rash.
Exposure to very high levels may affect the nervous system.
4. First Aid Measures
Skin: Rinse and then wash skin with water and soap.
Eyes: First rinse with plenty of water for several minutes (remove contact
lenses if easily possible), and then take to a doctor.
Inhalation: Refer for medical attention.
Ingestion: Rinse mouth. Refer for medical attention.
Note to physician: There is no specific antidote for Atrazine. If this product is
ingested, induce emesis or lavage stomach. The use of an aqueous slurry of
activated may be considered.
Antidote: not applicable
5. Fire-Fighting Measures
Flash point: >200 degree F
Extinguishing media: Powder, water spray, foam, carbon dioxide.
Fire fighting procedures: Assure protective clothing is worn and self-
contained breathing apparatus is used, Prevent runoff if possible.
Measures of personal protection: safety glasses or goggles, rubber gloves,
shoes plus socks, long-sleeved shirt, and long pants and hats.
6. Accidental Release Measures
Personal cautions: safety glasses or goggles, rubber gloves, shoes plus
socks, long-sleeved shirt, and long pants and hats.
Cleaning methods
EX: clear the material in time. Transfer to a properly labeled deposit that will
be closed and sealed until the recovery of elimination of the product.
Environmental cautions
EX: prevent the contamination of the floor and of beds of water.
7. Handling And Storage:
Storage: Provision to contain effluent from fire extinguishing. Separated from
food and feedstuffs.
Technical protective measures:
Fire and explosion protection: the area must be far from fire and flammable
materials, high temperature and strong oxidizers.
8. Exposure Controls / Personal Protection
Personal protective equipment
Respiratory protection: Ventilation
Protective gloves: safety gloves.
Eye protection: Safely spectacles.
Industrial hygiene: Industrial hygienists are available to answer your
questions regarding the control of chemical exposures using exhaust
ventilation, special work practices, good housekeeping, good hygiene
practices, and personal protective equipment including respirators. In
addition, they can help to interpret the results of industrial hygiene survey
data.

11. Toxicological Information
Contact with the skin: cause a skin allergy.
Contact with the eyes: irritate
Acute toxicity:
Oral LD50 (Rat) = 1,075-1,886 mg/kg
Dermal LD50 (Rabbit) = >5,000 mg/kg
Chronic toxicity: Some 40% of rats receiving oral doses of 20 mg/kg/day for 6
months died with signs of respiratory distress and paralysis of the limbs.
Structural and chemical changes in the brain, heart, liver, lungs, kidney,
ovaries, and endocrine organs were observed. Rats fed 5 or 25 mg/kg/day of
atrazine for 6 months exhibited growth retardation. In a 2-year study with
dogs, 7.5 mg/kg/day caused decreased food intake and increased heart and
liver weights. At 75 mg/kg/day, there were decreases in food intake and body
weight gain, increased adrenal weight, lowered blood cell counts, and
occasional tremors or stiffness in the rear limbs.
Reproductive effects: Dietary doses of atrazine given to rats on days 3, 6 and
9 of gestation up to about 50 mg/kg/day caused no adverse reproductive
effects.
Teratogenic effects: Atrazine does not appear to be teratogenic. In mice,
atrazine did not cause abnormalities in fetuses whose dams were given
doses of 46.4 mg/kg/day during days 6 through 14 of gestation.
Mutagenic effects: The weight of evidence from more than 50 studies
indicates that atrazine is not mutagenic.
Carcinogenic effects: Atrazine did not cause tumors when mice were given
oral doses of 21.5 mg/kg/day from age 1 to 4 weeks, followed by dietary
doses of 82 mg/kg for an additional 17 months. However, mammary tumors
were observed in rats after lifetime administration of high doses of atrazine.
Thus, available data regarding atrazine's carcinogenic potential are
inconclusive.
Organ toxicity: Lethal doses of atrazine in test animals have caused
congestion and/or hemorrhaging to the lungs, kidneys, liver, spleen, brain,
and heart. Long-term consumption of high levels of atrazine has caused
tremors, changes in organ weights, and damage to the liver and heart.
12. Ecological And Ecotoxicological Information
Effects on birds: Atrazine is practically nontoxic to birds. The LD50 is greater
than 2000 mg/kg in mallard ducks. At dietary doses of 5000 ppm, no effect
was observed in bobwhite quail and ring-necked pheasants.
Effects on aquatic organisms: Atrazine is slightly toxic to fish and other
aquatic life. Atrazine has a low level of bioaccumulation in fish. In whitefish,
atrazine accumulates in the brain, gall bladder, liver, and gut.
Effects on other organisms: Atrazine is non-toxic to bees.
13. Disposal Considerations
Spillage disposal: Do not wash away into sewer. Sweep spilled substance
into containers; if appropriate, moisten first to prevent dusting. Carefully
collect remainder, then remove to safe place.
