First Aid Measures

Inhalation: Move person to fresh air and keep comfortable for breathing. Mild symptoms may fade, but cough or shortness of breath means a hospital visit should follow.
Skin Contact: Wash with plenty of soap and water. Clothing splashed with chemical should get removed; persistent irritation means seeing a doctor.
Eye Contact: Rinse immediately with large amounts of water for at least 15 minutes. Eyelids should stay open for full flush. Medical evaluation is a must.
Ingestion: Rinse mouth, do not induce vomiting unless told to do so by a doctor. Medical attention is crucial even for mild symptoms.
Most Important Symptoms: Eye burning, persistent skin redness, cough, stomach pain if swallowed
Notes for Physicians: Treat based on symptoms; chemical burns possible in both skin and eyes. Respiratory irritation can develop into more serious consequences. Supportive care goes a long way here.

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray. Do not use direct water stream as this may spread chemical or create more hazardous vapor.
Special Hazards: Combustion produces nitrogen oxides, carbon oxides, and silicon oxides. Methanol gas released in fire raises explosion risk.
Protective Equipment: Firefighters must wear self-contained breathing apparatus and protective gear to avoid contact and toxic fumes.
Advice for Firefighters: Approach upwind to keep out of vapor. Remove containers from fire zone if safe. Dike runoff to prevent contamination of water sources.

Accidental Release Measures

Personal Precautions: Avoid direct contact with skin, eyes, and clothing. Respiratory protection needed in poorly ventilated spaces.
Emergency Procedures: Restrict access to spill area, ventilate location, and remove ignition sources.
Cleanup Methods: Absorb with inert material like sand or vermiculite, collect into sealed containers for disposal.
Environmental Precautions: Prevent chemical from entering drains, sewers, or waterways.
Advice for Response Teams: Wear full protective clothing, gloves, goggles, and chemical respirator if aerosolization likely.

Handling and Storage

Safe Handling: Use only in a well-ventilated area. Open containers slowly to control possible pressure buildup. Avoid breathing mist or vapors and wearing gloves is not optional.
Hygiene Measures: Wash hands thoroughly after use. Never eat, drink, or smoke in handling areas.
Storage Conditions: Store in original, tightly closed containers in a cool, dry, well-ventilated area. Keep away from water and acids, which can start a dangerous reaction.
Incompatibilities: Avoid contact with oxidizers, acids, and moisture. Storing near food or feed increases risk of contamination.

Exposure Controls and Personal Protection

Exposure Limits: No workplace exposure limits set for this material; watch for methanol byproduct (TWA 200 ppm)
Ventilation: Local exhaust or general room ventilation should pull vapor away from breathing space.
Respiratory Protection: NIOSH/MSHA approved respirators recommended if vapor exceeds safe concentration.
Hand Protection: Impermeable gloves like nitrile rubber work best. Check regularly for degradation.
Eye Protection: Chemical safety goggles or face shield worn at all times.
Skin and Body Protection: Long sleeve clothing and lab coats reduce risk of spills contacting skin.
Control of Environmental Exposure: Engineering controls must prevent discharge to environment.

pH: Approx. 10 (1% solution in water)
Melting Point/Freezing Point: Below -60°C
Boiling Point: Approx. 259°C
Flash Point: 145°C (closed cup)
Evaporation Rate: No reliable data, expected to be low

Decomposition Temperature: Above 250°C
Viscosity: Low, flows easily at room temperature

Stability and Reactivity

Reactivity: Reacts with moisture, strong acids, oxidizing agents; hydrolyzes to release methanol

Toxicological Information

Acute Toxicity: Oral LD50 (rat): approximately 2295 mg/kg; inhalation and skin toxicity lower, but eye and skin burns possible
Skin Corrosion/Irritation: Causes moderate to severe irritation depending on exposure time
Eye Damage/Irritation: Risk of serious damage and burns
Sensitization: Extended or repeated exposure brings risk of skin sensitization and allergic response
Mutagenicity: Not classified; no confirmed risk based on available data
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Reproductive Toxicity: No clear evidence of reproductive toxicity under typical laboratory conditions, but methanol byproduct poses hazard to unborn children

Symptoms of Exposure: Redness, pain, chemical burns, coughing, headache, dizziness, confusion (from methanol absorption)

Ecological Information

Ecotoxicity: Expected to be moderately toxic to aquatic life; decomposes in water to release methanol, which increases risk
Persistence and Degradability: Hydrolyzes in moist air and water, forming silanols and methanol; breakdown products degrade further under sunlight
Bioaccumulation Potential: Low for parent compound, but methanol can bioaccumulate
Mobility in Soil: Mobile when spilled, can infiltrate soil and reach groundwater
Other Adverse Effects: Discharge to waterways or drains puts aquatic systems at risk if not controlled

Disposal Considerations

Waste Treatment Methods: Dispose of waste in accordance with local, regional, and national regulations. Incineration with proper chemical scrubbers for air emissions often preferred.
Contaminated Packaging: Containers should get triple-rinsed, punctured, and consigned to hazardous waste sites
