Inhalation: Remove person to fresh air without delay. If breathing is difficult, trained personnel may give oxygen. Seek medical attention if breathing remains affected.
Skin Contact: Take off contaminated clothing and shoes. Rinse skin immediately with plenty of water for at least 15 minutes. Use soap for thorough cleaning. See healthcare provider if irritation persists.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Get medical advice if discomfort continues.
Ingestion: Rinse mouth with water. Never give anything by mouth to an unconscious person. Do not induce vomiting. Seek medical attention without delay.
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry chemical powder, or water spray.
Unsuitable Extinguishing Media: Avoid high volume water jet.
Special Hazards: Flammable vapors may form in confined, unventilated concentrations. Heating can release irritating and potentially toxic gases such as oxides of nitrogen, silicon oxides, and carbon oxides.
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective suit.
Fire Fighting Instructions: Move containers from fire area if almost safe. Use water spray to keep unopened containers cool.
Personal Precautions: Use engineered ventilation to minimize vapor build-up. Wear chemical-resistant gloves, goggles, and impervious clothing. Evacuate unprotected people from spill area.
Environmental Precautions: Prevent release into sewers, drains, soil, and waterways.
Clean-up Methods: Contain spilled liquid with sand or earth. Collect in suitable, labeled containers for proper disposal. Wash area with soap and water. Ventilate spill area well.
Precautions for Safe Handling: Avoid contact with skin, eyes, and clothing. Work in a fume hood or well-ventilated environment. Do not breathe vapors or mists. Remove contaminated clothing before entering eating areas.
Storage Conditions: Store in tightly closed containers in a cool, dry, well-ventilated place. Keep away from heat, sparks, open flames, and sources of ignition. Segregate from acids, oxidizers, and moisture.
Incompatible Materials: Water, moisture, strong acids, and strong oxidizing agents.
Special Handling Notes: Use clean, dedicated equipment. Practice good industrial hygiene by cleaning up spills immediately.
Exposure Limits: No official occupational exposure limits for Bis[3-(Triethoxysilyl)Propyl]Amine
Engineering Controls: Use local exhaust or process enclosure where possible. Avoid generating vapors.
Personal Protective Equipment:
—Eye Protection: Chemical splash goggles or face shield
—Hand Protection: Nitrile, neoprene, or butyl rubber gloves
—Skin Protection: Lab coat or chemical resistant coveralls
—Respiratory Protection: Use NIOSH-approved organic vapor respirator under conditions where airborne concentrations are high
—Hygiene Measures: Wash hands before breaks and after handling, do not eat or drink in work area
Appearance: Clear to yellowish liquid

Auto-Ignition Temperature: 280°C
Decomposition Temperature: Not determined
Viscosity: 19–25 mPa·s at 25°C
Chemical Stability: Stable under recommended storage temperatures/conditions.
Possibility of Hazardous Reactions: Moisture initiates slow hydrolysis, releasing ethanol. Reaction with strong oxidizers may generate exothermic conditions.
Incompatible Materials: Water, moisture, acids, oxidizing agents. Mixing with water causes hydrolysis and potential for pressure build-up in sealed containers.
