Skin Contact: Remove contaminated clothing, flush skin with copious water for several minutes, seek medical advice for persistent irritation
Eye Contact: Use eye wash station for at least 15 minutes, keep eyelids open, consult a physician if discomfort persists
Ingestion: Rinse mouth, do not induce vomiting, get medical help immediately; information on possible delayed symptoms should be relayed to responders
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam, water spray for larger fires
Specific Hazards: Combustion releases carbon oxides, hazardous vapors possible if material decomposes
Protective Equipment: Firefighters use full protective gear with self-contained breathing apparatus; skin and eye protection recommended
Special Procedures: Approach from upwind, contain run-off water, prevent entry into water sources and drains
Personal Precautions: Ensure adequate ventilation, avoid breathing dust/vapors, put on chemical-resistant gloves and eye protection
Environmental Precautions: Prevent spillage from entering soil, waterways, and sewer systems; inform authorities if significant release occurs
Cleanup Methods: Collect and transfer spilled material to secure, labeled containers for disposal; wash down area with water and detergent; dispose of contaminated material following regulations
Handling: Use in well-ventilated environments, avoid contact with skin, eyes, and clothing, handle with compatible chemical-resistant gloves and eye protection
Hygiene Measures: Wash thoroughly after handling, do not eat, drink, or smoke near material
Storage Conditions: Store in tightly closed containers, keep in a cool, dry, well-ventilated area away from incompatible substances or open flames; limit exposure to moisture and heat
Engineering Controls: Fume hood or local exhaust ventilation, splash-proof sinks for eye and skin washing
Personal Protection: Gloves (nitrile or neoprene), safety goggles, lab coat or apron, in certain settings a respirator rated for organic vapors
Exposure Limits: No established occupational exposure limits, maintain levels as low as reasonably achievable
Environmental Controls: Use closed systems where possible, monitor air quality for vapors, provide spill kits

Reactivity: Non-reactive under standard conditions, highly exothermic with strong oxidants
Routes of Exposure: Inhalation, skin absorption, ingestion, eye contact
Acute Effects: Eye and skin irritation, possible headache or dizziness after inhalation
Chronic Effects: No data on reproductive toxicity or carcinogenicity, repeated contact may cause dermatitis
LD50 (Oral, Rat): Estimated >2000 mg/kg based on structurally similar compounds
Sensitization: Not classified as skin sensitizer
Further Effects: No data suggesting mutagenicity or teratogenicity; standard laboratory care reduces risk
Ecotoxicity: Limited data, low anticipated acute aquatic toxicity
Persistence and Degradability: Readily biodegradable in environmental conditions
Bioaccumulation Potential: Expected to be low, low log Kow value
Mobility in Soil: Moderate mobility, unlikely to persist
