Most Important Symptoms: Irritation to exposed tissues, respiratory distress in severe exposure
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray
Unsuitable Extinguishing Media: High pressure water streams, which may spread contaminated runoff
Hazardous Combustion Products: Hydrogen chloride gas, nitrogen oxides, carbon monoxide
Special Protective Equipment: Firefighters need self-contained breathing apparatus, chemical-resistant clothing
Fire Hazards: Fine particulate may ignite in presence of strong ignition sources, hazardous gases possible at high temperatures
Personal Precautions: Evacuate unnecessary personnel, ventilate affected area, use appropriate personal protective equipment
Environmental Precautions: Avoid discharge into drains, surface water, or soil
Spill Response: Collect powdered material using dust-minimizing techniques, transfer to labeled waste container, clean residue with damp paper or cloth and collect for disposal
Precautions for Safe Handling: Avoid formation of dust, work in efficiently ventilated areas, wear skin and eye protection
Hygienic Measures: Wash hands thoroughly after handling, keep work clothing separate from personal garments

Acute Toxicity: Data for similar compounds indicate low to moderate acute toxicity
Effects of Exposure: Eye and skin irritation, upper respiratory tract discomfort, gastrointestinal effects if ingested
Skin Sensitization: Repeated contact could increase sensitivity
Chronic Toxicity: Prolonged exposure may affect liver or kidneys, based on general aromatic amine chemistry
Carcinogenicity: No specific data available, aromatic amines warrant caution for possible carcinogenic risk
Aquatic Toxicity: Data unavailable for this chemical; similar benzophenone derivatives may show moderate toxicity to aquatic organisms
Persistence and Degradability: Reasonable chemical stability may lead to persistence in the environment
Bioaccumulation: Potential for bioaccumulation exists due to lipid solubility profile
Mobility in Soil: Likely to adhere to soil and sediment particles
