Hazards from Combustion: Produces nitrogen oxides, silicon oxides, carbon monoxide, carbon dioxide, possible toxic fumes
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective gear
Special Procedures: Cool containers exposed to heat, prevent run-off from entering drains or waterways
Personal Precautions: Evacuate unnecessary personnel, wear chemical-resistant gloves, eye protection, suitable respiratory equipment
Environmental Precautions: Contain spill to prevent entry into drains, sewers, or water bodies
Methods for Cleaning Up: Absorb with inert material like dry sand or earth, collect in containers for disposal, ventilate area thoroughly, wash spill site after material is removed
Reference for Disposal: Refer to local, regional, national regulations governing chemical disposal
Precautions for Handling: Practice good industrial hygiene, avoid contact with eyes, skin, and clothing, do not inhale vapors or mists, use in well-ventilated areas
Safe Storage Conditions: Keep tightly sealed in original container, store in cool, dry, well-ventilated place out of direct sunlight, keep away from strong oxidizers, acids, moisture
Storage Temperature: 15–25°C recommended for safe handling
Incompatible Materials: Strong acids, strong bases, oxidizing agents, moisture
Occupational Exposure Limits: No established limits available for this compound
Engineering Controls: Use fume hood or local exhaust ventilation, maintain eye wash stations and safety showers nearby
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, chemical splash apron or lab coat, approved respirator for vapors or mists
Hygiene Practices: Avoid eating, drinking, or smoking in work areas, always wash hands after use, remove contaminated clothing before entering clean areas
Physical State: Liquid
Appearance: Colorless to pale yellow
Odor: Ammonia-like
Boiling Point: 279°C (approximate)
Melting Point: Not determined
Flash Point: >110°C (closed cup)
Flammability: Not classified as flammable
Vapor Pressure: <0.5 mmHg at 25°C
Solubility: Partially soluble in water, reacts slowly to form silanols and ethanol
Density: 0.96 g/cm³ at 25°C
pH (1% solution): 10–11 (alkaline)
Viscosity: Low to moderate
Partition Coefficient (n-octanol/water): Not available
Chemical Stability: Stable in sealed containers under recommended conditions, hydrolyzes in presence of moisture
Reactivity: Reacts with acids and strong oxidizing agents, contact with water causes hydrolysis, releasing ethanol
Hazardous Decomposition Products: Ammonia, ethanol, nitrogen oxides, silicon dioxide
Polymerization: Hazardous polymerization not expected under normal conditions
Conditions to Avoid: Moisture, heat, sources of ignition, incompatible materials
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Harmful if swallowed, inhaled, or absorbed through the skin — may cause burns and irritation
Skin Corrosion/Irritation: Causes severe skin burns
Eye Damage/Irritation: Causes serious eye damage
Respiratory Effects: Mist or vapor inhalation can cause respiratory irritation
Sensitization: Not classified as a sensitizer based on available data
Carcinogenicity: Not classified by IARC, NTP, OSHA
Mutagenicity/Reproductive Toxicity: No data indicating a risk
Chronic Effects: Prolonged exposure may cause dermatitis or delayed respiratory symptoms
Ecotoxicity: No comprehensive data, but likely hazardous in large quantities due to pH shift and release of organosilicon compounds
Mobility: May hydrolyze in moist soil or water, products can leach into groundwater
Persistence/Degradability: Silane degrades slowly, hydrolysis products more biodegradable
Bioaccumulative Potential: Expected to have low bioaccumulation
Other Adverse Effects: Ethanol and amines released during hydrolysis can damage local aquatic ecosystems if discharged in quantity
Waste Disposal Methods: Dispose by approved chemical waste incineration, follow national and local laws
Contaminated Packaging: Empty containers and liners hold residues, treat as hazardous waste
Special Precautions: Do not discharge to sewers or waterways
Recycling/Reuse: Not recommended due to residual contamination
