COMMAND 480 EC HERBICIDE

SECTION 2: Hazards identification

OSHA EMERGENCY OVERVIEW: • Straw yellow liquid with an aromatic solvent odor. • Moderately combustible. May support combustion if heated above the product's flash point (see Section 9, "Physical and Chemical Properties" below). • Thermal decomposition and burning may form toxic by-products. • For large exposures or fire, wear personal protective equipment. • Slightly to moderately toxic to fish and aquatic organisms. Keep out of drains and water courses. • Moderately irritating to the eyes.

Potential health effects

Effects from overexposure result from either swallowing, inhaling or coming into contact with the eyes or skin. Symptoms of overexposure include decreased activity, tearing eyes, bleeding from the nose and incoordination.

FIRST AID MEASURES EYES: Flush with water for at least 15 minutes. If irritation occurs and persists, contact a medical doctor. SKIN: Wash with plenty of soap and water. Get medical attention if irritation occurs and persists. INGESTION: Do not induce vomiting and do not give liquids of any kind to the person. Never give anything by mouth to an unconscious person. INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, contact a medical doctor. NOTES TO MEDICAL DOCTOR: This product is expected to have low oral, dermal and inhalation toxicity. It is expected to be moderately irritating to the eyes and slightly irritating to the skin. Direct contact with eyes may produce corneal damage, especially if not washed out immediately. Contains aromatic hydrocarbons that may produce a severe pneumonitis if aspirated during vomiting. Consideration should be given to gastric lavage with an endotracheal tube in place. 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: 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. 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 tools and equipment, wash with a 20% solution of potassium hydroxide in methanol. Follow by washing with strong soap and rinsing with water, and add both solutions to the drums of waste already collected. To clean and neutralize spill areas, spray the area with a 20% solution of potassium hydroxide in methanol. Cover the treated area with plastic and let stand for 24 hours. Remove the covering and place in a drum for later disposal. Wash the area, three times, with a strong soap and rinse with water. If spill occurs on a wooden surface, repeat the entire process again. Absorb, as above, any excess liquid and add to the drums of waste already collected. Dispose of drummed waste according to the method outlined in Section 13,

TOXICOLOGICAL INFORMATION

EYE EFFECTS: Expected to be moderately irritating. (rabbit) SKIN EFFECTS: Expected to be slightly irritating. (rabbit) DERMAL LD50: No data available. Similar product: > 2,000 mg/kg (rabbit) ORAL LD50: No data available. Similar product: 1,406 mg/kg (rat) INHALATION LC50: No data available. Similar product: 4.47 mg/l (4 h) (rat) ACUTE EFFECTS FROM OVEREXPOSURE: This product is expected to have low oral, dermal and inhalation toxicity. It is expected to be moderately irritating to the eyes and slightly irritating to the skin. Large dosages of clomazone ingested by laboratory animals produced signs of toxicity including ataxia, decreased activity, oral discharge, lacrimation, bloody tears, and nasal discharge. Inhalation of aromatic hydrocarbon vapors may cause dizziness, disturbances in vision, drowsiness, 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. Ingestion of calcium dodecylbenzene sulfonate may cause irritation of the mouth and stomach. Prolonged contact may cause skin irritation or a drying affect. Exposure to butanol vapors may produce headaches, drowsiness and irritation of the nose and throat. Excessive exposures to butanol liquid or vapors may result in contact dermatitis and irritation of the mucous membranes. No data available for the formulation Clomazone technical: Freshwater fish: 96-hour LC50 = 19 mg/L (Rainbow trout) (slightly toxic) Freshwater fish: 96-hour LC50 = 34 mg/L (Bluegill sunfish) (slightly toxic) Estuarine invertebrates: 96-hour LC50 = 8.9 mg/L (Pink shrimp) (moderately toxic) Estuarine fish: LC50 = 6.3 mg/L (Atlantic silverside, moderately toxic) - 41 mg/L (Sheepshead minnow, slightly toxic) Estuarine invertebrate: LC50 = 0.57 mg/L (Mysid) (highly toxic) Waterfowl / Upland game birds: Oral LD50 >2510 mg/kg; Dietary LC50 >5620 ppm (low toxicity) Care should be taken to avoid contamination of the aquatic environment. 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. 14. TRANSPORT INFORMATION U.S. DEPARTMENT OF TRANSPORTATION (DOT) PACKAGING TYPE: Non-Bulk

Potential chronic health

FROM OVEREXPOSURE No data available for the formulation. In studies with laboratory animals, clomazone did not cause reproductive toxicity,

Teratogenic Effects

or carcinogenicity. Liver enlargement and elevated cholesterol levels are often noted in laboratory animals that have ingested large doses of clomazone during their lifespan. An overall absence of genotoxicity has been demonstrated in tests of mutagenicity, DNA damage and chromosome aberrations. Chronic exposure to aromatic hydrocarbons may cause headaches, dizziness, loss of sensations or feelings (such as numbness), and liver and kidney damage. Chronic exposure to trimethylbenzenes may cause CNS changes, asthmatic bronchitis and blood dyscrasias. Disturbances in hearing and balance have been reported in workers exposed to butanol vapors. Inhalation of xylene vapors at high doses has also resulted in an increased incidence of malformations and decreases in fetal weight in laboratory animals. Damage from xylene may be potentiated by alcohol.

ECOLOGICAL INFORMATION

Unless otherwise indicated, the data presented below are for the active ingredient(s). ENVIRONMENTAL DATA: No data available for the formulation. Clomazone has a moderate rate of degradation in soil (half-life = 24 days), and is stable to hydrolysis over a wide range of pH. The bioconcentration potential for clomazone is low, with a Log Pow of 2.5, and a measured bioconcentration factor (BCF) of 27 - 40. Field studies showed that clomazone does not significantly leach below 15 cm in soil and is, therefore, not expected to enter groundwater.
