Special Fire-Fighting Procedures: Evacuate downwind areas, use water spray to cool exposed containers, contain runoff
Additional Advice: Avoid inhaling smoke or combustion products
Personal Precautions: Evacuate unprotected personnel from area, ventilate the area, avoid breathing vapors, wear appropriate personal protection (see Exposure Controls)
Environmental Precautions: Prevent further leakage, avoid discharge into soil, sewers, or natural water bodies
Containment Methods: Contain spill with inert, non-combustible absorbent material (sand, diatomaceous earth), transfer to properly-labelled waste container
Clean-Up Procedures: Sweep up carefully, collect spilled material, dispose of in accordance with regulations
Decontamination: Wash area with water to remove residues, avoid creating dust or aerosols
Precautions for Safe Handling: Wear chemical resistant gloves and goggles, work in well-ventilated space, avoid contact with skin, eyes, clothing, keep away from ignition sources, do not breathe vapors or mist, wash hands after handling
Conditions for Safe Storage: Store in tightly closed, original container, in cool, dry, and well-ventilated area, keep away from direct sunlight, heat, oxidizers, acids, and moisture; inert gas blanketing recommended if available
Incompatibilities: Strong oxidizing agents, strong acids, water (hydrolysis may occur upon contact)
Storage Temperature: Keep below 40°C/104°F if possible
Other Storage Protocols: Clear labelling of containers, secure against overturning, secondary containment as required for flammable liquids
Occupational Exposure Limits: No established limit for this compound; maintain levels as low as possible

Decomposition Temperature: >200°C
Viscosity: 1-3 mPa·s
Chemical Stability: Stable under recommended conditions, reacts slowly with water and moist air
Possibility of Hazardous Reactions: Contact with strong oxidants, acids, or bases accelerates decomposition; hydrolyzes forming methanol, may release flammable or toxic gases in fire

Incompatible Materials: Oxidizing agents, strong acids, moisture, strong bases
Hazardous Decomposition Products: Methanol, cyclohexylamine, nitrogen oxides, siloxanes, carbon monoxide, carbon dioxide
Acute Toxicity: Oral LD50 (rat): estimated 500-2000 mg/kg, inhalation or dermal data not specifically reported
Skin Corrosion/Irritation: Causes skin irritation, repeated or long-term contact may lead to dermatitis

Reproductive Toxicity: Not classified as toxic to reproduction
Specific Target Organ Toxicity (Single/Repeated Exposure): May cause respiratory tract irritation
Aspiration Hazard: Not classified, but viscosity and volatility suggest possible aspiration risk if ingested
Other Effects: Prolonged or repeated exposure may cause effects to liver, kidneys, or central nervous system
Ecotoxicity: Limited acute aquatic toxicity data; hydrolysis products may pose risk to aquatic organisms; methanol and siloxanes may affect water organisms
Persistence and Degradability: Hydrolyzes in water over time, primary decomposition yields methanol and aminoalkyl silanes which are biodegradable under aerobic conditions
Bioaccumulative Potential: Not expected to bioaccumulate; hydrolysis products have moderate bioaccumulation risk
