In case of fire: Use alcohol-resistant foam, dry chemical, or carbon dioxide for extinction.
Chemical Name: 2,2,3,4,4,4-Hexafluorobutyl Methacrylate
Concentration: 98–100%
Impurities: Trace stabilizer (e.g., hydroquinone, ≤0.1%)
CAS Number: 364-57-6
Inhalation: Move person to fresh air. Provide oxygen or artificial respiration if required. Seek medical attention if respiratory symptoms develop.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with plenty of water and soap. Seek medical care for persistent irritation.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek medical help if irritation persists.
Ingestion: Rinse mouth. Do not induce vomiting. Seek immediate medical advice.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide
Special Hazards: Vapors may form explosive mixtures with air. Combustion releases carbon oxides, hydrogen fluoride, toxic fumes.
Protective Equipment: Full protective gear, self-contained breathing apparatus
Precautions: Cool exposed containers with water spray. Avoid inhalation of combustion products.
Personal Precautions: Evacuate area if vapors are present. Eliminate ignition sources. Wear chemical-resistant gloves, safety goggles, and suitable protective clothing.
Environmental Precautions: Prevent spills from entering drains, soil, or water bodies.
Methods for Cleaning Up: Contain spillage with inert material (sand, earth). Collect in suitable containers for disposal. Ventilate area and wash spill site after material clean up is complete.
Handling: Work in areas with proper ventilation or fume extraction. Keep containers tightly closed. Use spark-proof tools and explosion-proof equipment. Avoid contact with skin, eyes, and clothing.
Storage: Store in a cool, dry, well-ventilated area away from direct sunlight, heat, and incompatible materials like strong oxidizers, acids, and bases. Keep in original container, securely sealed, and labeled.
Occupational Exposure Limits: No occupational exposure limit established specifically for this compound; handle with precaution due to irritation and inhalation risks.
Engineering Controls: Use mechanical ventilation or local exhaust to keep airborne concentrations below exposure limits. Employ closed system operation if possible.
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, lab coat or chemical-resistant clothing, suitable respiratory protection if ventilation is inadequate.
Hygiene Measures: Avoid eating, drinking, or smoking while handling. Wash hands thoroughly after use.
