4. FIRST AID MEASURES
EYES: Flush with water for at least 15 minutes. If irritation occurs and persists, obtain medical
attention.

INGESTION: Drink plenty of water. Never give anything by mouth to an unconscious person. If any
discomfort persists, obtain medical attention.
INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, obtain
medical attention.
NOTES TO MEDICAL DOCTOR: This product is expected to have low oral, dermal and
inhalation toxicity, and to be mildly irritating to the skin and eyes. Treatment is otherwise controlled
removal of exposure followed by symptomatic and supportive care.
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Foam, CO2 or dry chemical. Soft stream water fog only if
necessary. Contain all runoff.
FIRE / EXPLOSION HAZARDS: Slightly combustible. This material may support
combustion at elevated temperatures.
Page 2 of 8
SULFENTRAZONE SODIUM SALT IN WATER (F18-17-7) Date: 11/24/2004
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.
6. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES: This solution, in contact with an acidic material, will cause sulfentrazone
technical to precipitate out.
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.
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
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. Do not contaminate other materials,
or allow this material to be contaminated, by improper storage or handling.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS: Use local exhaust at all process locations where vapor or
mist may be emitted. Ventilate all transport vehicles prior to unloading.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: For splash, mist or spray exposure, wear chemical protective goggles
or a face shield.
RESPIRATORY: For splash, spray or mist exposure wear, as a minimum, a properly
fitted half-face or full-face air-purifying respirator with dust/mist/fume cartridges (approved by
U.S. NIOSH/MSHA, EU CEN or comparable certification organization). Respirator use and
selection must be based on airborne concentrations.
PROTECTIVE 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 or laminate suit. Leather items - such as shoes,

SULFENTRAZONE SODIUM SALT IN WATER (F18-17-7) Date: 11/24/2004
belts and watchbands - that become contaminated should be removed and destroyed. Launder all
work clothing before reuse (separately from household laundry).
GLOVES: Wear chemical protective gloves such as Silvershield庐 brand or neoprene.
Thoroughly wash the outside of gloves with soap and water prior to removal. Inspect regularly for
leaks.
WORK HYGIENIC PRACTICES: 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
EYE EFFECTS: Expected to be mildly irritating. No data available for the salt.
sulfentrazone: Mildly irritating (rabbit)
Page 4 of 8
SULFENTRAZONE SODIUM SALT IN WATER (F18-17-7) Date: 11/24/2004
SKIN EFFECTS: Expected to be non-irritating No data available for the salt.
sulfentrazone: Non-irritating (rabbit)
DERMAL LD50: sulfentrazone: > 2,000 mg/kg (rabbit)
ORAL LD50: sulfentrazone: 2,689 mg/kg (rat)
INHALATION LC50: sulfentrazone: > 4.13 mg/l (4 h) Maximum attainable concentration - zero
mortality
SENSITIZATION: No data available for the salt.
sulfentrazone: Non-sensitizing (guinea pig) Skin
ACUTE EFFECTS FROM OVEREXPOSURE: This product is expected to have low
oral, dermal and inhalation toxicity, and to be mildly irritating to the eyes and non-irritating to the skin.
Signs of toxicity in laboratory animals included clonic convulsions, ataxia, hypersensitivity to touch,
chromorhinorrhea, abdominogenital staining, decreased locomotion, lacrimation, nasal discharge and
squinting eyes.
CHRONIC EFFECTS FROM OVEREXPOSURE: This product was not mutagenic
in the Ames mutagenicity assay. Sulfentrazone was not carcinogenic in lifetime feeding studies with
laboratory animals, nor was it found to be mutagenic in a battery of tests. In a reproduction study,
sulfentrazone produced adverse effects on the growth and survival of the offspring, decreased male fertility
and oligospermia at 25 mg/kg/day, and 35 mg/kg/day. Sulfentrazone was found to be fetotoxic in oral and
dermal developmental toxicity studies; the fetal NOELS were 10 mg/kg/day and 100 mg/kg/day,
respectively. At labeled use rates and practices of mixing and applying, expected exposure to farm workers
is at least one hundred times lower than the doses that produced effects in laboratory animals.
CARCINOGENICITY:
NTP: Not listed
IARC: Not listed
OSHA: Not listed
OTHER: Not Listed (ACGIH)
12. ECOLOGICAL INFORMATION
No data available for the formulation. Data presented below are based on sulfentrazone technical.
ENVIRONMENTAL DATA: Sulfentrazone is stable in soil (half-life = 18 months). In water,
sulfentrazone is stable to hydrolysis over the pH range of 5 to 9, however, it will readily undergo photolysis
(half-life < 0.5 day). Sulfentrazone has a low affinity for organic matter (Koc = 43), but is mobile only in
soils with high sand content. The potential for sulfentrazone to bioaccumulate is very low, having a Log
Pow of 1.48, and a bioconcentration factor of 1.1 - 2.0.

ECOTOXICOLOGICAL INFORMATION: Sulfentrazone is slightly toxic to fish and
aquatic arthropods, with LC50 values ranging from 60.4 mg/L to > 130 mg/L. Sulfentrazone has a very low
order of toxicity to upland game birds (oral LD50 > 2,250 mg/kg).
13. DISPOSAL CONSIDERATIONS
DISPOSAL METHOD: Open dumping or burning of this material or its packaging is prohibited.
If spilled material cannot be recovered and reused, 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 agencies should be
contacted prior to disposal.
EMPTY CONTAINER: 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.
