Other Ingredients: Solvents, emulsifiers, or carriers present in formulated products (refer to specific product label for composition); may include xylene, emulsifiers, surfactants
Impurities: May contain trace amounts of unreacted starting materials or degradation products
Inhalation: Move exposed person to fresh air; if symptoms persist seek medical attention; use supportive care for difficulty breathing
Skin Contact: Remove contaminated clothing and wash skin thoroughly with soap and water; seek medical advice for persistent irritation or allergic response
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, keeping eyelids open; get medical attention if irritation continues
Ingestion: Rinse mouth, do not induce vomiting unless instructed by a physician or poison control; never give anything by mouth to an unconscious person; seek immediate medical advice
Notes to Physician: Treat symptoms; consider possibility of respiratory distress; monitor for allergic reactions or neurological symptoms
Suitable Extinguishing Media: Dry chemical, CO2, foam, or water spray in large amounts
Unsuitable Extinguishing Media: Direct water jet for small fires as it may spread contamination
Specific Hazards: Emits toxic fumes (carbon monoxide, nitrogen oxides, hydrogen fluoride) during combustion; risk of hazardous runoff to environment
Protective Equipment: Firefighters use self-contained breathing apparatus (SCBA) and full protective gear
Advice for Firefighters: Move containers from fire area if safe; cool containers with flooding amounts of water; avoid runoff or release to sewers and waterways
Personal Precautions: Keep out unnecessary personnel; wear recommended protective clothing including gloves, goggles, and respirator
Environmental Precautions: Avoid contamination of water sources; prevent further leakage or spillage if safe; alert authorities in case of large spills impacting water bodies
Cleanup Methods: Use inert absorbent (sand, earth, vermiculite) to mop up; collect material in sealed, labelled container for disposal; flush residue with water and detergent; ventilate area
Decontamination: Wash contaminated surfaces and equipment with detergent; avoid washing into sewers
Precautions for Safe Handling: Ensure adequate ventilation; avoid contact with skin, eyes, and clothing; prevent inhalation of dust, vapor, or spray; do not eat, drink, or smoke in work area; use dedicated equipment for mixing and application
Storage Conditions: Store in original, tightly closed container; keep in cool, dry, well-ventilated location away from food, feed, and incompatible materials (oxidizing agents, acids); avoid exposure to direct sunlight and high temperatures
Incompatibilities: Strong oxidizers, acids, strong bases; materials causing excessive heat
Safe Transfer: Employ safe transfer techniques to avoid spills or dust generation; maintain labeling
Occupational Exposure Limits: No specific limit established for flucythrinate; limit exposure as for other hazardous pesticides
Engineering Controls: Use local exhaust ventilation at points of dust, vapor, or mist generation; containment where possible
Personal Protective Equipment: Respiratory protection suitable for pesticide application (N95 or better); chemical-resistant gloves (nitrile, neoprene); long-sleeved clothing; safety goggles; face shield if risk of splashing
Hygiene Measures: Wash thoroughly after handling, before eating or drinking, and after removing protective clothing; keep contaminated clothing separate; launder before reuse
Environmental Controls: Prevent release to the environment; use application methods that minimize exposure
Appearance: Off-white to pale yellow crystalline solid (technical grade); emulsifiable concentrate or wettable powder for commercial formulations
Odor: Slight aromatic or chemical odor
Melting Point: 62–64°C
Boiling Point: Decomposes before boiling
Density: 1.24–1.27 g/cm3 (at 20°C)
Solubility: Low in water (~0.0002 mg/L at 20°C); soluble in organic solvents such as acetone, xylene, methanol
pH: 5–7 (1% aqueous solution)
Vapor Pressure: Very low (5 x 10−6 Pa at 25°C)
Partition Coefficient (log Pow): 6.2–6.6
Flashpoint: >95°C (for most formulated products)
Chemical Stability: Product remains stable under recommended storage conditions; excessive heat or long-term light exposure may cause degradation
Reactivity: Not highly reactive under normal circumstances; avoid strong oxidizers and acids
Hazardous Reactions: Under fire conditions, toxic gases such as hydrogen fluoride, nitrogen oxides, carbon oxides may form
Decomposition Products: Thermal decomposition yields hazardous fumes; risk increases with high temperature
Polymerization: Does not self-polymerize
Acute Oral Toxicity: LD50 (rat) 10–40 mg/kg (highly toxic)
Acute Dermal Toxicity: LD50 (rat) 200–1000 mg/kg
Acute Inhalation Toxicity: LC50 (rat, 4h) >0.25 mg/L
Skin Irritation: Causes moderate irritation; risk of allergic skin reaction in sensitive individuals
Eye Irritation: Causes conjunctival irritation and mild corneal injury
Chronic Toxicity: Animal studies show nervous system effects from repeated exposures; some evidence of liver and kidney impacts
Carcinogenicity: Not classified as carcinogen in standard animal studies; lack of evidence in humans
Symptoms of Exposure: Headache, nausea, numbness, muscle twitching, abnormal sensation around mouth, respiratory irritation; long-term effects possible with chronic exposure
Toxicity to Fish: Extremely toxic to fish (LC50 < 0.01 mg/L for rainbow trout and carp)
Toxicity to Aquatic Invertebrates: Very toxic to daphnia and other small aquatic organisms
Toxicity to Birds: Moderately toxic to birds; LD50 (mallard duck) ~500 mg/kg
Toxicity to Bees: Highly toxic to bees (contact and oral LD50 < 0.1 μg/bee)
Environmental Persistence: Breaks down slowly in soil and water; may accumulate and persist under some conditions
Bioaccumulation: Lipophilic nature leads to potential for bioconcentration in aquatic and terrestrial food chains
Degradability: Degrades by microbial action; photolysis (sunlight) can speed degradation on surfaces
Mobility in Soil: Low; binds strongly to soil particles, low leaching to groundwater
