General Advice: Remove contaminated clothing and shoes; wash before reuse
If Inhaled: Move exposed person to fresh air, keep at rest, seek medical attention if symptoms develop or persist
If on Skin: Immediately wash skin with plenty of soap and water; seek medical advice for persistent symptoms
If In Eyes: Rinse cautiously with water for several minutes; remove contact lenses if easy to do, get medical help
If Swallowed: Rinse mouth, drink water if conscious, do not induce vomiting, get medical attention right away
Most Important Symptoms: Redness, irritation, discomfort in eyes, throat, skin, potential headache or nausea after significant exposure
Suitable Extinguishing Agents: Dry chemical, carbon dioxide, foam, or water spray
Specific Hazards: Toxic fumes of hydrogen bromide, hydrogen chloride, carbon oxides release with combustion
Special Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Advice for Firefighters: Prevent runoff from entering drains, collect contaminated water separately, stay upwind
Explosion Hazards: Does not present known explosion risk under normal handling and storage
Personal Precautions: Use chemical splash goggles, suitable gloves, and lab coat; avoid dust generation
Emergency Procedures: Evacuate people from area not involved in clean-up, ventilate space well
Containment: Sweep or vacuum minor spills into appropriate sealed container for waste disposal
Cleaning Methods: Clean residues using damp cloth with mild detergent, dispose of materials safely
Environmental Precautions: Prevent entry into sewage, drains, or watercourses, inform authorities if significant release escapes
Safe Handling Practices: Open containers with care, avoid inhalation, skin, and eye contact, minimize generation and accumulation of dust, only handle in well-ventilated areas or fume hoods
Safe Storage Conditions: Store in tightly closed containers, cool dry location, avoid direct sunlight and incompatible substances
Incompatibilities: Strong oxidizers, strong acids, bases may react with this compound
Special Handling Advice: Do not eat, drink, or smoke in the handling area, keep containers clearly labeled, use tools instead of direct contact

Vapor Pressure: Negligible at ambient temperature
Density: 1.54 g/cm3 (estimated)
pH: Not applicable (solid)
Partition Coefficient: log Kow not determined
Flash Point: Not determined, likely above room temperature
Other: Stable crystalline form, not volatile at room temperature, dust may irritate airways
Chemical Stability: Stable under recommended conditions of storage and handling
Conditions to Avoid: Exposure to excessive heat, open flame, direct sunlight, strong oxidizers, strong acids or bases
Incompatible Materials: Reacts with powerful oxidizing agents, strong acids or bases, may decompose with release of bromine or chlorine-containing vapors
Hazardous Decomposition Products: Hydrogen halides, carbon monoxide, carbon dioxide can be released in fire or during decomposition
Reactivity: No dangerously violent reactions reported with normal chemical use
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Harmful if swallowed (estimated LD50 oral, rat: 500–1000 mg/kg); low toxicity by skin contact
Skin Irritation: Causes irritation, possible redness and inflammation
Eye Damage: May cause discomfort, redness, watering
Respiratory Sensitization: Breathing dust may irritate respiratory tract
Chronic Effects: Repeated exposure could lead to drying, cracking of skin; no human carcinogenicity, mutagenicity, or reproductive toxicity data
Other Effects: Symptoms include headache, dizziness, or mild nausea after high exposure
Ecotoxicity: No specific data, structurally similar benzophenones show toxicity to aquatic life (fish, invertebrates) in low ppm range
Persistence and Degradability: Not readily biodegradable in aquatic or soil environments
Bioaccumulative Potential: Potential for bioaccumulation based on structure and limited solubility
Mobility in Soil: Likely low mobility; strong adsorption possible due to hydrophobic structure
Other Adverse Effects: Discharge to water systems may cause long-term negative effects for aquatic organisms
Disposal Methods: Send waste and contaminated materials to approved chemical disposal facilities; do not pour down drain
Contaminated Packaging: Treat empty containers with care, dispose of as hazardous waste
Precautions: Avoid release into the environment; incinerate only at licensed facilities with scrubbing of halogen acid gases
Recycle/Reuse: Consider usage of any leftover material in permitted research or validated procedures whenever safe and possible
