Signal Word: Warning
Hazard Statements: Causes eye irritation. May cause an allergic skin reaction. Toxic to aquatic life with long lasting effects.
Precautionary Statements: Avoid contact with skin and eyes. Wear protective clothing. Wash hands after handling. Prevent release to the environment.
GHS Label: Exclamation mark, Environment symbol
Active Ingredient: Flumetsulam; 70-85%
Other Ingredients: Inert carriers and formulation aids such as surfactants, dispersing agents; 15-30%
Impurities: At typical levels below safety thresholds for reporting
Eye Contact: Remove contact lenses, rinse eyes with plenty of water for at least 15 minutes. Seek medical attention if irritation continues.
Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing. If irritation or swelling develops, seek medical attention.
Inhalation: Move person to fresh air. Keep comfortable for breathing. If symptoms persist, consult a doctor.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Seek immediate medical attention if feeling unwell.
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: Avoid direct streams of water which may spread fire or dissolved product
Fire and Explosion Hazards: Dust may form explosive mixtures with air. Product decomposes at high temperatures releasing toxic fumes (nitrogen oxides, carbon oxides, sulfur oxides).
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Personal Precautions: Wear chemical resistant gloves, protective eyewear, coveralls, and a dust mask or respirator.
Environmental Precautions: Prevent release to drains, surface water, or soil.
Methods for Clean Up: Sweep up and collect for proper disposal. If spilled on land, remove contaminated soil. Clean surface thoroughly after removal.
Safe Handling: Always use in a well-ventilated area. Avoid inhaling dust and contact with skin or eyes. Wash hands before breaks and after work.
Safe Storage: Store in a tightly closed container in a cool, dry, well-ventilated area, away from direct heat or sunlight. Keep away from food, animal feed, and incompatible materials such as strong oxidizers.
Storage Temperature: Above freezing and below 40°C recommended for optimum stability.
Exposure Limits: No specific occupational exposure limits established for Flumetsulam.
Engineering Controls: Provide adequate local exhaust ventilation. Use closed systems for industrial applications.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, chemical-resistant coveralls, respirators with organic vapor/dust cartridges if airborne exposure may occur.
Hygiene Measures: Remove contaminated clothing and wash before reuse. Wash face, hands, and forearms with soap and water after handling.
