Specific Hazards from Fire: Emits toxic fumes (nitrogen oxides, carbon monoxide, carbon dioxide), vapors may form explosive mixtures with air, vapor is heavier than air and may spread along floors
Special Protective Equipment: Self-contained breathing apparatus (SCBA), full protective gear including chemical-resistant gloves and boots
Fire Fighting Procedures: Move containers from fire area if safe, use water to cool containers, avoid inhaling fumes
Personal Precautions: Evacuate non-essential personnel, ventilate area, stop leak if safe
Protective Equipment: Chemical-resistant gloves, goggles, lab coat, respirator if vapor exposure exceeds limits
Environmental Precautions: Prevent entry into drains, sewers, surface and ground waters
Clean-up Methods: Absorb with inert material such as sand or earth, use spark-proof tools, place in labeled containers for disposal, ventilate and wash site after material pickup is complete
Emergency Procedures: Contact local authorities if large spill, prevent vapors from accumulating in low areas
Handling: Use only in fume hood or well-ventilated area, avoid contact with skin and eyes, keep away from heat, flames, and sources of ignition, do not eat, drink, or smoke during handling, ground and bond containers when transferring
Storage: Store in tightly closed, properly labeled containers in cool, dry, well-ventilated area away from incompatible materials, keep away from sunlight, oxidizing agents, acids, strong bases, segregate from foodstuffs
Incompatibilities: Strong oxidizing agents, acids, halogens, acid anhydrides, chloroformates
Exposure Limits: No ACGIH or OSHA PEL specific to compound, recommend ceiling values based on amine class: approx 5 ppm
Engineering Controls: Local exhaust ventilation, eyewash stations, safety showers
Respiratory Protection: Approved organic vapor respirator if exposure limits may be exceeded
Skin Protection: Chemical-resistant gloves (nitrile, neoprene), long-sleeved lab coat or chemical apron
Eye Protection: Chemical splash goggles, face shield when splash risk exists
General Hygiene: Wash hands before breaks, after handling, and after removing gloves and protective equipment

Symptoms: Irritation of eyes and skin, burning sensation, cough, sore throat, headache, dizziness, drowsiness, nausea, vomiting
Carcinogenicity: No data indicating carcinogenicity
Reproductive Toxicity: No data; comparable amines have low risk but long exposure not recommended
