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.
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: 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. Large spills should be covered to prevent
dispersal. For dry material, use a wet sweeping compound or water to prevent the formation of dust. If
water is used, prevent runoff or dispersion of excess liquid by diking and absorbing with a non-combustible
absorbent such as clay, sand or soil. Vacuum, shovel or pump all waste material, including absorbent, 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
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.

PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: For dust exposure, wear chemical protective goggles or a face shield.
RESPIRATORY: For dust exposures 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.
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 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).
GLOVES: Wear chemical protective gloves made of materials such as butyl rubber, nitrile 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, chewing gum, or using tobacco. Shower at
the end of the workday.

skin. Signs of toxicity in laboratory animals included tremors, convulsions, salivation, diarrhea, coma,
hypoactivity and piloerection.
Effects observed in laboratory animals after acute inhalation of toluene included mucous membrane
irritation, motor incoordination, prostration, changes in respiratory rate, changes in serum and blood

AUTHORITY鈩? MTZ HERBICIDE (F18-58-2) Date: 04/18/2007
enzyme activities, elevated blood glucose and packed cell volume, decreased body weight and death.
Vomiting after ingestion of this product may cause aspiration of toluene into the lungs, which may result in
fatal pulmonary edema.
CHRONIC EFFECTS FROM OVEREXPOSURE: No data available for the
formulation. 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.
In studies with laboratory animals, metribuzin did not cause carcinogenicity, genotoxicity, it had no
reproductive effects, and no developmental toxicity effects. Metribuzin can cause depression of the central
nervous system, and target organs are the thyroid gland and the liver.
Repeated overexposure to crystalline silica for extended periods has caused acute silicosis. The
International Agency for Research on Cancer (IARC) has classified crystalline silica, inhaled in the form of
quartz or cristobalite from occupational sources, as carcinogenic to humans (Group 1). The National
Toxicology Program (NTP) has classified respirable crystalline silica (quartz, cristobalite and tridymite) as
"reasonably anticipated to be carcinogenic". The American Conference of Governmental Industrial
Hygienists (ACGIH) has concluded that sulfuric acid, contained in strong inorganic acid mists, is a
'Suspected Human Carcinogen' (A2 - limited evidence of carcinogenicity in humans and sufficient evidence
of carcinogenicity in experimental animals with relevance to humans).
Chronic exposure to toluene may cause headaches, dizziness, loss of sensations or feelings (such as
numbness), and liver and kidney damage. Inhalation of toluene vapors at high doses have also resulted in an
increased incidence of malformations and decreased fetal weight in laboratory animals.

12. ECOLOGICAL INFORMATION
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.
Metribuzin is moderately persistent in soil. The half-life varies according to soil type and climactic
conditions with soil half-lives of 30 - 120 days. Metribuzin is poorly bound to most soils and soluble in
water with a potential for leaching in many soil types. Microbial degradation is the major mechanism for
loss from soil. The half-life of metribuzin in pond water is approximately 7 days.
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 waterfowl (dietary LC50 > 5620 ppm) and upland game birds (oral LD50 > 2,250 mg/kg).
Metribuzin is moderately to slightly toxic to birds, and slightly toxic to fish:

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
