General Tips: Move the exposed individual to fresh air. Remove contaminated clothing. Seek medical advice for any symptoms. Inhalation: Remove victim to fresh air. Keep at rest in a position comfortable for breathing. Seek medical attention if symptoms such as coughing, shortness of breath, or dizziness occur. Skin Contact: Immediately wash affected skin with plenty of soap and water for at least 15 minutes. Remove contaminated clothing and shoes. Seek medical help if irritation persists. Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical advice if irritation remains. Ingestion: Rinse mouth with water. Do NOT induce vomiting. Seek immediate medical attention. Give nothing by mouth to an unconscious person.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, water spray Unsuitable Extinguishing Media: Do not use a solid water stream, as it may spread the fire Hazards from Combustion: Vapors can form explosive mixtures with air. May emit toxic fumes including nitrogen oxides, carbon monoxide, carbon dioxide, and other irritating fumes under fire conditions. Protective Equipment for Firefighters: Wear full protective clothing and self-contained breathing apparatus (SCBA). Special Firefighting Procedures: Cool fire-exposed containers with water spray. Move containers from fire area if safe to do so. Evacuate area and fight fire from a safe distance.
Personal Precautions: Evacuate unprotected personnel. Provide adequate ventilation. Wear suitable personal protective equipment including gloves, eye protection, and an organic vapor respirator. Avoid inhaling vapors and contact with skin and eyes. Environmental Precautions: Prevent runoff from entering drains, sewers, or watercourses. Inform appropriate authorities if release threatens the environment or public safety. Methods for Clean-Up: For small spills, absorb with inert absorbent materials such as sand, earth, or vermiculite and place in a sealed, labeled disposable container. For large spills, dike far ahead of liquid spill for later disposal. Clean contaminated surface thoroughly. Wash spill area with plenty of water after material pick-up is complete. Containment: Stop leak if it can be done safely. Prevent further leakage or spillage if safe to do so.
Precautions for Safe Handling: Avoid breathing vapors or mist. Avoid contact with skin, eyes, and clothing. Use only in well-ventilated areas. Ground and bond container and receiving equipment to reduce static discharge. Keep away from sources of ignition – no smoking. Use spark-proof tools and explosion-proof equipment. Conditions for Safe Storage: Store in a tightly closed container in a cool, dry, well-ventilated area away from heat, sparks, open flames, and strong oxidizing agents. Keep container tightly sealed when not in use. Store away from acids and halogens. Keep separate from incompatible materials. Storage Temperature: Store at ambient temperature (15–25°C) unless otherwise specified.
Exposure Limits: No occupational exposure limits established for this compound, but handle with precautions recommended for aliphatic amines. Engineering Controls: Use local or general exhaust ventilation. Ensure eye wash stations and safety showers are easily accessible in the area of use. Personal Protective Equipment (PPE): Wear liquid-resistant gloves (nitrile, neoprene), chemical splash goggles, face protection, and lab coat or chemical-resistant clothing. Use an approved air-purifying respirator if airborne concentrations approach unsafe levels. Hygiene Measures: Do not eat, drink, or smoke during use. Remove and wash contaminated clothing before reuse. Wash hands and face thoroughly after handling.

Chemical Stability: Stable under recommended storage conditions. Reactivity: Reacts with acids to form salts and with strong oxidizing agents, producing possible risk of fire or explosion. Conditions to Avoid: Heat, flames, sparks, static discharge, and direct sunlight. Incompatible Materials: Strong oxidizing agents, strong acids, acid chlorides, acid anhydrides, and halogens. Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides, and irritating/aliphatic vapors.
Routes of Exposure: Inhalation, skin absorption, ingestion, and eye contact. Acute Toxicity: LD50 (oral, rat): 220 mg/kg (based on similar aliphatic amines). LD50 (dermal, rabbit): 750 mg/kg (estimated). LC50 (inhalation, rat): Not available, but expected to be hazardous based on volatility and amine toxicity. Skin Corrosion/Irritation: Causes irritation, redness, pain, and possible blistering. Eye Damage/Irritation: Contact may result in severe irritation, redness, pain, and possible corneal damage. Respiratory Sensitization: Irritating to respiratory tract, causing coughing, sore throat, and headaches. Prolonged or repeated exposure may aggravate pre-existing lung or skin conditions. Germ Cell Mutagenicity: Data not available. Not expected to be mutagenic at low exposures. Carcinogenicity: Not listed as carcinogenic by IARC, OSHA, or NTP. Reproductive Toxicity: No evidence of reproductive toxicity from existing animal studies. STOT – Single Exposure: May cause respiratory tract irritation, drowsiness, or dizziness. STOT – Repeated Exposure: Prolonged exposure may result in damage to liver or kidneys. Aspiration Hazard: No data available.
Toxicity to Aquatic Life: Harmful to aquatic organisms based on similar amines. Estimated LC50 (fish, 96h): 68 mg/L; EC50 (daphnia, 48h): 54 mg/L. Persistence and Degradability: Readily biodegradable under aerobic conditions. Bioaccumulative Potential: Low. Minimal accumulation in aquatic organisms expected based on water solubility and partition coefficient. Mobility in Soil: High mobility anticipated due to water miscibility. Likely to leach into groundwater if released into environment. Other Adverse Effects: Products of degradation include nitrogen compounds that may contribute to eutrophication in water bodies.
Waste Disposal Methods: Collect and dispose of waste in accordance with local, regional, and federal regulations. Do not dispose of in household garbage, storm drains, or watercourses. Incineration is the preferred method for significant quantities, with suitable emission controls. Contaminated Packaging: Triple rinse and puncture containers before disposal. Send to a licensed drum reconditioner or incinerator. Special Precautions: Ensure disposal is carried out in a controlled environment. Avoid environmental contamination by thoroughly decontaminating surfaces and equipment used.
