Inhalation: Move away from exposure immediately, supply fresh air, seek medical attention if respiratory irritation persists or worsens.
Skin Contact: Remove contaminated clothing, rinse under running water for at least 15 minutes, use mild soap, and contact medical personnel if irritation continues.
Eye Contact: Rinse eyes thoroughly with gentle stream of water for at least 15 minutes, lift eyelids frequently, seek medical attention urgently.
Ingestion: Do not induce vomiting, rinse mouth, drink water if conscious, call poison control center or doctor promptly.
Most Important Symptoms: Burning sensation, irritation, redness to skin and eyes, coughing or discomfort after inhalation
Suitable Extinguishing Agents: Dry chemical, carbon dioxide, foam, water spray
Hazards Arising from Chemical: May emit toxic fumes, including carbon oxides, nitrogen oxides, silicon oxides upon combustion
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing
Specific Hazards: Vapors may be heavier than air, collect in low lying areas, risk of explosion if heated in confined spaces
Personal Precautions: Evacuate unprotected personnel, ventilate area, wear appropriate respirator, gloves, goggles, and protective clothing
Environmental Precautions: Prevent entry to drains, sewers, soil, and surface water
Cleanup Methods: Absorb with inert material such as sand or vermiculite, place in suitable waste container, seal and label for hazardous disposal
Decontamination: Wash area with detergent and water thoroughly, avoid contact with absorbed material
Handling: Open containers in well-ventilated locations, avoid inhaling vapors, prevent skin and eye contact, do not eat or drink while using product, keep work clothes separate from other laundry
Storage: Store in tightly sealed original containers, keep cool and dry, protect from moisture and direct sunlight, keep away from incompatible materials such as strong oxidizers, acids, and bases, store in designated chemical area with appropriate signage and secondary containment
Occupational Exposure Limits: None established for this chemical. Follow supplier or workplace recommendations, and monitor for signs of irritation.
Engineering Controls: Use local exhaust, maintain eye wash stations, monitor air quality regularly
Personal Protective Equipment: Chemical-resistant gloves (nitrile or butyl rubber), splash goggles, protective clothing, respiratory protection if ventilation inadequate
Hygiene Measures: Wash thoroughly after handling, before eating, and remove contaminated clothing prior to breaks or leaving work area
Appearance: Clear to pale yellow liquid
Odor: Amine-like, slight to moderate
Boiling Point: 270-290°C (estimated)
Melting Point: Less than -50°C
Flash Point: About 120°C (closed cup)
Vapor Pressure: Low at 20°C
Solubility: Hydrolyzes in water, soluble in organic solvents
Relative Density: 1.01–1.05 g/cm³
Viscosity: Low viscosity, flows easily
pH: Not relevant in pure form, may increase in water due to amine group
Auto-ignition Temperature: Not readily self-igniting under normal handling conditions
Chemical Stability: Stable under recommended handling and storage conditions
Reactivity: Hydrolyzes with water, releases methanol
Conditions to Avoid: High heat, moisture, exposure to acids or bases
Incompatible Materials: Strong oxidizers, acids, bases, moisture
Hazardous Decomposition Products: Methanol, carbon oxides, nitrogen oxides, silicon oxides
Routes of Exposure: Ingestion, inhalation, skin, and eye contact
Acute Effects: Harmful if swallowed, inhaled, or absorbed through skin; irritates skin and eyes, causes respiratory irritation
Chronic Effects: No long-term human data available; animal studies point to possible effects on central nervous system and liver at high levels
Sensitization: Not expected, but repeated exposure could increase sensitivity
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Reproductive Effects: Not well studied, avoid unnecessary exposure especially in pregnancy
Toxicity Data - LD50 (oral, rat): Approximately 1000-2000 mg/kg, varies by source
Aquatic Toxicity: Harmful to aquatic organisms; limited biodegradation in water
Mobility in Soil: May leach into soil, hydrolyzes when exposed to moisture
Persistence and Degradability: Hydrolysis produces silanols and methanol; degradation in environment influenced by pH and sunlight
Bioaccumulation Potential: Expected to be low based on log Kow values and rapid hydrolysis, but breakdown products may be more mobile
Other Adverse Effects: Prevent large spills from reaching water systems to avoid ecosystem damage
Disposal Methods: Dispose of as hazardous chemical waste through licensed professional services; incineration with afterburner and scrubber recommended
Container Disposal: Do not reuse containers. Triple rinse then offer for recycling or dispose according to local regulations
Special Precautions: Never dump into drains, sewers, or open environment
Waste Codes: Obtain from local authorities depending on use and region
