Main Ingredient: 2-Chlorofluorobenzene (purity typically exceeds 98%)
Impurities: Possible traces of related halogenated benzenes
Hazardous Components: No significant additives, most hazards stem from the main compound
Inhalation: Remove to fresh air, keep person at rest, medical help needed for breathing trouble
Skin Contact: Wash with soap and water, remove contaminated clothing, seek help for persistent irritation
Eye Contact: Rinse cautiously with water for several minutes, remove lenses, consult a doctor if irritation continues
Ingestion: Rinse mouth, get medical advice, do not induce vomiting
Special Note: Immediate attention helps minimize risk of delayed symptoms
Suitable Extinguishing Methods: Use foam, dry chemical, or carbon dioxide
Specific Hazards: Can produce toxic fumes like hydrogen chloride and hydrogen fluoride upon combustion
Advice for Firefighters: Wear self-contained breathing apparatus and protective clothing
Explosion Risk: Vapors may form explosive mixtures with air in confined spaces
Personal Precautions: Use personal protective equipment, avoid breathing vapors
