(0=Insignificant 1=Slight 2=Moderate 3=High 4=Extreme)
SECTION 4. FIRST AID
Eyes: Flush eyes thoroughly with water for several minutes. Remove contact lenses, if present, after initial
1-2 minutes and continue flushing for several additional minutes. If effects occur, consult a physician,
preferably an ophthalmologist.
Skin: Wash skin with plenty of water.
Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by medical
personnel.
Note to Physician: The decision of whether to induce vomiting or not should be made by a
physician. If lavage is performed, suggest endotracheal and/or esophageal control. Danger from lung
aspiration must be weighed against toxicity when considering emptying the stomach. No specific
antidote. Treatment of exposure should be directed at the control of symptoms and the clinical
conditions of the patient.
Inhalation: Move person to fresh air; if effects occur, consult a physician.

SECTION 5. FIRE AND EXPLOSION HAZARDS
Flash Point: 210潞F (99潞C).
Test Method: PMCC
LFL Flammable Limits (based on solvent; 77掳F (25掳C)): 1.8% approximately.
UFL Flammable Limits: 11.8% approximately.
Autoignition Temperature: Not available.
Flammability Classification: Nonflammable.
Known Hazardous Products of Combustion: Nitrogen oxides, carbon monoxide, carbon dioxide, and
fluorinated hydrocarbons.
Properties that Initiate/Contribute to Intensity of Fire: Not available.
Potential For Dust Explosion: None.
Reactions that Release Flammable Gases or Vapors: None known.
Potential For Release of Flammable Vapors: Not known.
Unusual Fire & Explosion Hazards: Closed containers may explode due to pressure build-up
when subjected to excessive heat or intense fire.
Extinguishing Media: Water, CO2, or dry chemicals.
Special Firefighting Procedures: Dense smoke emitted when burned without sufficient oxygen.
Keep people away. Isolate fire area and deny unnecessary
entry. Closed containers may explode due to pressure build-up
when subjected to excessive heat or intense fire. Containers
exposed to intense heat from fires should be kept cool with
water to prevent container weakening or rupture. Move
container away from fire area if this is possible without hazard.
Contain firewater run-off if possible. Firewater run-off if not
contained may cause environmental damage.
Wear positive-pressure self contained breathing apparatus
(SCBA) and protective fire fighting clothing (includes fire
fighting helmet, coat, pants, boots and gloves).
SECTION 6. SPILLS AND LEAKS
Containment: Product is toxic to fish. Prevent product spillage from entering drinking water supplies or streams.
Clean Up: Collect liquid or absorb onto non-reactive absorbent material and package for disposal according to
local, state and federal regulations.
Evacuation: Not necessary but restrict entry.
Reporting: When spills of trifluralin and naphthalene exceed the RQ it must be reported as a priority pollutant
under the CERCLA spill reporting requirements.
SECTION 7. STORAGE AND HANDLING
Storage: Store in original container only. Store above 40潞F; avoid freezing. If frozen, poor weed control
may result. Do not store near heat or open flame. Do not contaminate water, food or feed. Do
not stack pallets more than two (2) high.
Transfer Equipment: Transfer product using chemical-resistant plastic or stainless steel tanks, pumps, valves, etc.
SECTION 8. PERSONAL PROTECTIVE EQUIPMENT
Eyes: Protective eyewear.
Skin: Long sleeved shirt and long pants; chemical-resistant gloves such as Barrier Laminate or Viton; shoes
plus socks.
Respiratory: Atmospheric levels should be maintained below the exposure guidelines (see Section 2). When
respiratory protection is required for certain operations, use a NIOSH approved air-purifying respirator.
Ventilation: Provide general and/or local exhaust ventilation to control airborne levels below the exposure
guidelines.

SECTION 10. STABILITY AND REACTIVITY
Stability: Stable under recommended storage conditions.
Conditions To Avoid: Avoid freezing. Do not store near heat or open flame.
Incompatibility: Avoid contact with strong oxidizers.
Hazardous Decomposition Products: May include but are not limited to carbon dioxide, carbon monoxide,
nitrogen oxides, and fluorinated hydrocarbons.
Hazardous Polymerization: Not known to occur.
SECTION 11. POTENTIAL HEALTH EFFECTS
Acute Effects:
Eyes: May cause moderate eye irritation. Corneal injury is unlikely.
Skin: Brief contact may cause slight skin irritation with local redness. May cause drying or flaking of the
skin. Prolonged skin contact is unlikely to result in absorption of harmful amounts. The LD50 for
skin absorption in rabbits is >5000 mg/kg. Has caused allergic skin reactions when tested in
guinea pigs.
Ingestion: Low toxicity if swallowed. Small amounts swallowed incidental to normal handling operations
are not likely to cause injury; however, swallowing larger amounts may cause injury. Aspiration
into the lungs may occur during ingestion or vomiting, causing lung damage or even death due to
chemical pneumonia. The oral LD50 for rats is 3738 mg/kg.
Inhalation: No adverse effects are anticipated from single exposure to vapor. The LC50 for rats is 5.59 mg/L
(males) and >6.05 mg/L (females) for 4 hours.
Systemic (Other For trifluralin, in animals, effects have been reported on the following organs: blood, kidney and
Target Organ) liver. For the solvent, in animals, effects have been reported on the following organs: lungs,
Effects: stomach, thyroid gland and urinary tract. Cataracts and other eye effects have been reported in
humans repeatedly exposed to naphthalene vapor or dust.
Cancer A low incidence of urinary tract tumors was seen in only 1 of 5 chronic studies in rats with
Information: trifluralin. Trifluralin is not anticipated to be a carcinogenic risk to man. Contains naphthalene,
which has caused cancer in some laboratory animals.
Teratology (Birth Trifluralin did not cause birth defects in animals; other fetal effects occurred only at doses toxic to
Defects): the mother.

SECTION 12. ECOLOGICAL INFORMATION
Movement & Partitioning:
Based largely or completely on information for trifluralin: Bioconcentration potential is moderate (BCF between 100
and 3000 or Log Pow between 3 and 5). Potential for mobility in soil is slight (Koc between 2000 and 5000).
Based largely or completely on information for Aromatic 200: Bioconcentration potential is high (BCF is >3000 or
Log Pow between 5 and 7).
Degradation & Persistence:
Based largely or completely on information for trifluralin: Based on the stringent OECD test guidelines, this material
cannot be considered as readily biodegradable; however, these results do not necessarily mean that the material is not
biodegradable under environmental conditions.
Based largely or completely on information for Aromatic 200: Biodegradation may occur slowly under aerobic
conditions (in the presence of oxygen).
Ecotoxicology:
Based largely or completely on information for trifluralin: Material is very highly toxic to aquatic organisms on an
acute basis (LC50 or EC50 <0.1mg/L in most sensitive species).
Based largely or completely on information for Aromatic 200: Material is highly toxic to aquatic organisms on an acute
basis (LC50 or EC50 is between 0.1 and 1mg/L in most sensitive species). Material is practically non-toxic to birds on a
dietary basis (LC50 is>5000ppm). Material is practically non-toxic to birds on an acute basis (LD50 is >2000 mg/kg)
SECTION 13. DISPOSAL
Do not contaminate food, feed, or water by storage or disposal. Wastes are toxic. Improper disposal or excess waste, spray
