General Advice: Move affected person to fresh air; remove contaminated clothing and shoes.
Inhalation: Remove to fresh air quickly; seek medical attention if any symptoms persist or worsen.
Skin Contact: Wash thoroughly with plenty of water and mild soap; seek medical attention if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes, holding eyelids open; seek urgent medical care if irritation continues.
Ingestion: Rinse mouth—do not induce vomiting; seek immediate medical attention.
Most Important Symptoms/Effects: Immediate symptoms may include irritation, pain, or swelling; delayed effects could stem from repeated exposure.
Suitable Extinguishing Media: Use dry chemical powder, foam, or carbon dioxide; avoid water streams that may spread fire.
Special Hazards: Vapors may form explosive mixtures with air; combustion releases carbon oxides, silicon dioxide, and irritating fumes.
Advice for Firefighters: Wear positive-pressure self-contained breathing apparatus and full protective gear; keep containers cool with water spray.
Hazard Combustion Products: Carbon monoxide, carbon dioxide, silicon oxides, small quantities of formaldehyde during incomplete combustion.
Flash Point: Typically between 85°C to 90°C; always check actual lot specification.
Personal Precautions: Equip all team members with chemical-resistant gloves and goggles; ventilate spill area immediately.
Spill Cleanup: Absorb with earth, sand or other non-combustible material; collect in appropriate waste containers.
Environmental Precautions: Prevent from entering drains, surface water, or soil; inform authorities if large spills occur.
Methods for Containment: Dike area to contain the spill; clean thoroughly with detergents, avoid creating static discharge in the area.
Decontamination: Wash contaminated surfaces and dispose of cleaning agents as hazardous waste.
Safe Handling: Handle only in well-ventilated spaces; avoid breathing vapor or mist; use spark-proof tools and explosion-proof equipment.
Storage Conditions: Store in original, tightly closed container; keep away from ignitable sources; store below 40°C; protect from moisture and hydrolysis.
Incompatible Materials: Strong oxidizers, water, alcohols, acids, and bases; avoid long-term exposure to humid atmosphere.
Transfer Precautions: Prevent static build-up by grounding and bonding containers and equipment.
Exposure Limit Values: No specific occupational exposure limit established; maintain as low as reasonably possible.
Engineering Controls: Use local exhaust ventilation; fume hood recommended for laboratory tasks.
Personal Protection—Respiratory: Wear NIOSH-approved organic vapor respirator if ventilation is inadequate.
Personal Protection—Skin: Chemical-resistant gloves (nitrile, neoprene), apron, and boots as needed.
Personal Protection—Eyes: Chemical safety goggles or full-face shield.
General Hygiene: Wash hands thoroughly before breaks and after handling; do not eat, drink, or smoke around chemical.
Appearance: Clear, colorless to slightly yellowish liquid.
Odor: Mild ether-like or solvent smell.
Odor Threshold: Not determined.
pH: Not applicable (not soluble in water).
Melting Point: Below -50°C.
Boiling Point: Around 285°C.
Flash Point: 85-90°C (closed cup).
Evaporation Rate: Slower than butyl acetate.
Flammability: Flammable liquid and vapor.
Vapor Pressure: Less than 1 mmHg at 20°C.
Vapor Density: Estimated greater than air (air = 1).
Relative Density: About 1.06 g/mL at 25°C.
Solubility: Hydrolyzes slowly in water; soluble in alcohols, ethers, and many organics.
Partition Coefficient (n-octanol/water): Expected high; may bioaccumulate.
Auto-ignition Temperature: Above 240°C.
Decomposition Temperature: Not precisely defined; avoid high heat.
Chemical Stability: Stable when kept dry and tightly closed; hydrolyzes on moisture exposure.
Conditions to Avoid: Contact with water or humid air, elevated temperatures, sources of ignition.
Hazardous Reactions: Violent reaction on contact with strong oxidizing agents; forms flammable gases when hydrolyzed by water.
Decomposition Products: Methyl ethers, ethylene glycol derivatives, and silicon oxides; possible low-level formaldehyde in fire conditions.
Polymerization: Not known to occur under normal handling.
Acute Toxicity: LD50 (oral, rat): estimated near 5,000 mg/kg; LD50 (dermal, rabbit): similar range.
Skin Corrosion/Irritation: Causes moderate irritation; repeated contact may cause dermatitis.
Serious Eye Damage/Irritation: Eye exposure can provoke severe discomfort, redness, and tearing.
Respiratory or Skin Sensitization: No strong evidence for sensitization, but precaution matters.
Chronic Toxicity: Repeated or prolonged inhalation/skin contact may harm health.
Carcinogenicity: Not classifiable regarding carcinogenic potential.
Mutagenicity and Reproductive Toxicity: No data showing significant risk in standard tests.
Ecotoxicity: Direct aquatic toxicity data sparse; similar silanes show moderate risk to aquatic life in concentrated spills.
Persistence and Degradability: Hydrolyzes in water to produce silanols and glycols, both degrade in environment.
Bioaccumulative Potential: Some potential due to high partition coefficient; bioaccumulation not expected to be severe.
Mobility in Soil: Expected to bind to soil minerals after hydrolysis; low mobility as parent compound.
Other Adverse Effects: Releases semi-volatile organic compounds slowly; not likely to contribute significantly to ozone formation.
Waste Treatment Methods: Use licensed hazardous waste contractor for disposal; incinerate only in equipped facilities.
Product Disposal: Dispose content/container in accordance with national regulations and environmental authority requirements.
Contaminated Packaging: Handle empty containers as hazardous waste due to residue; do not reuse for other chemicals.
Special Precautions: Avoid discharge to sewer; prevent environmental release.
