Signal Word: Warning
Pictograms: Flame, exclamation mark, environment
Routes of Exposure: Inhalation, skin, eyes, ingestion
Acute Symptoms: Dizziness, headache, nausea, coughing, skin redness, irritation
Long-Term Effects: Repeated or prolonged exposure could affect liver or kidneys, chronic inhalation may impair respiratory health
Component: 2-Fluorotoluene
Concentration: >99%
Impurities: Trace amounts of other fluoro-toluenes, benzyl derivatives
Hazardous Components: 2-Fluorotoluene only
Solvent: No added solvent
Inhalation: Move to fresh air, keep at rest, seek medical attention if symptoms persist or worsen, provide oxygen if breathing is difficult
Skin Contact: Remove contaminated clothing, wash skin thoroughly using soap and water, consult a healthcare provider for persistent irritation
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical advice if redness or discomfort continues
Ingestion: Rinse mouth with water, do not induce vomiting, get medical attention promptly, keep person calm and at rest
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Media: Water jet may spread fire
Fire Hazards: Vapors can form explosive mixtures with air, combustion produces toxic gases (hydrogen fluoride, carbon monoxide, carbon dioxide)
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear, keep containers cool with water spray to prevent explosion, stay upwind to avoid inhalation of fumes
Special Protective Equipment: Chemically resistant boots and gloves, helmet, face shield, breathing apparatus recommended
Personal Precautions: Evacuate area, ventilate, eliminate ignition sources, use personal protective equipment to avoid exposure
Environmental Precautions: Prevent entry into drains, surface water, or soil, notify authorities if product contaminates environment
Spill Cleanup Methods: Absorb with inert materials like sand or vermiculite, collect in sealed containers for disposal, use non-sparking tools
Decontamination: Clean area with detergent and water, ventilate
Handling: Keep away from heat, sparks, open flames, and static discharge, use explosion-proof electrical equipment, avoid inhalation of vapors, use only in well-ventilated areas, do not eat, drink, or smoke while handling
Storage: Store in tightly closed containers in a cool, flameproof, and dry location, segregate from oxidizing agents, store away from incompatible materials like acids, ensure adequate ventilation
Transfer Precautions: Ground and bond containers when transferring liquid to prevent static discharge
Workplace Limits: No established occupational exposure limit for 2-Fluorotoluene, but recommended to keep vapor concentration as low as possible
Engineering Controls: Use chemical fume hood, local exhaust ventilation to maintain airborne concentrations below recommended levels
Personal Protective Equipment (PPE): Chemical-resistant gloves, safety goggles or face shield, flame-retardant lab coat or apron, respirator if ventilation is inadequate, closed footwear
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before eating or leaving the work area, do not reuse contaminated PPE
