Ingestion: Rinse mouth with water. Do not induce vomiting. Get medical assistance promptly.
Suitable Extinguishing Media: Dry chemical powder, CO2, alcohol-resistant foam, water spray
Hazards from Combustion: Can release toxic fumes such as phosphorus oxides, nitrogen oxides, carbon oxides on burning
Protective Equipment: Firefighters should wear self-contained breathing apparatus and complete protective clothing
Special Procedures: Cool surrounding containers with water spray; avoid inhaling smoke or combustion products
Personal Precautions: Don gloves, goggles, lab coat; avoid all direct contact
Spill Procedures: Sweep up the spill, contain and collect as dry as possible; place in proper waste container
Environmental Precautions: Prevent entry into streams, storm sewers, or soil; clean up promptly to minimize environmental exposure
Ventilation: Use adequate exhaust or fume hoods
Handling: Avoid ingestion, inhalation, and direct skin or eye contact; wash hands thoroughly after handling; use in ventilated space
Storage: Keep in tightly closed container, stored in a cool, dry, and well-ventilated area; segregate from incompatible substances such as strong oxidizers
Special Considerations: Label storage areas and containers clearly; keep away from heat and sources of ignition
Engineering Controls: Use chemical fume hood or local exhaust
Personal Protective Equipment: Wear impervious gloves, chemical splash goggles, long-lab coats
Respiratory Protection: If exposure limits are exceeded or irritation experienced, use an approved respirator
Hygiene Measures: Wash thoroughly after handling, before eating, drinking, or smoking; keep work area clean
Appearance: Colorless to pale yellow viscous liquid or crystalline solid (room temperature may influence form)
Odor: Faint, slightly amine-like
Melting Point: 40–70 °C (estimate, form dependent)
Boiling Point: Decomposes before boiling
