First Aid Measures

Eye Contact: Rinse with plenty of clean water for several minutes; remove contact lenses if present; seek medical attention immediately
Skin Contact: Wash with soap and water; remove contaminated clothing; seek medical attention if irritation develops or persists
Inhalation: Move victim to fresh air; keep at rest; consult a physician if breathing becomes difficult
Ingestion: Rinse mouth, do not induce vomiting; get medical support as soon as possible
Notes to Physician: Treat symptomatically; consider delayed effects from chemical exposure

Fire-Fighting Measures

Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, or water spray
Unsuitable Media: Direct water jet may spread chemical
Unusual Fire Hazards: Vapors may form explosive mixtures with air; containers can rupture or explode under intense heat
Special Protective Equipment: Self-contained breathing apparatus and full protective clothing recommended
Decomposition Products: Carbon oxides, silicon oxides, formaldehyde, and other toxic fumes
Advice for Firefighters: Use water spray to cool exposed containers; prevent runoff from entering sewers or waterways

Accidental Release Measures

Personal Precautions: Evacuate area; use personal protective equipment including gloves, goggles, and respirators
Environmental Precautions: Prevent solution from entering drains, surface water, or groundwater
Spill Cleanup Methods: Absorb with inert material (sand, earth, diatomite); collect in sealable containers for proper disposal; ventilate affected area
Decontamination: Wash spill site with copious water after material pick-up; avoid use of solvents that increase volatility
Reporting: Notify environmental, health, and safety authorities as required by regulatory agencies

Handling and Storage

Handling: Use only with adequate ventilation; avoid skin or eye contact; do not inhale vapors or mist; keep away from incompatible materials including strong oxidizing agents and acids
Storage: Store in tightly closed, original containers; keep in a cool, dry, well-ventilated area; avoid temperature extremes; product reacts with moisture, so protect from humidity
Storage Materials: Use containers made from resistant materials such as HDPE or glass
Incompatible Materials: Water, alcohols, acids, oxidizers; avoid exposure to humid air
Safe Storage Practices: Inspect containers regularly for leaks or cracks; label containers clearly; restrict access to trained personnel

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limit for parent compound; monitor for methanol as hydrolysis product (TWA 200 ppm ACGIH)
Engineering Controls: Ensure efficient local exhaust at workplaces; use closed handling systems where feasible
Personal Protection: Chemical splash goggles or face shield; Nitrile rubber gloves; long-sleeved protective clothing
Respiratory Protection: If ventilation is insufficient, use NIOSH-certified organic vapor respirator
Hygiene Measures: Wash hands and exposed skin thoroughly after handling; do not eat or drink near material; change contaminated clothing promptly

Polymerization: Not expected under normal conditions, avoid elevated temperatures and contaminants

Toxicological Information

Acute Toxicity: Oral LD50 (rat) >2000 mg/kg for major component
Inhalation Toxicity: High vapor concentrations irritate respiratory tract; methanol released as hydrolysis product can cause central nervous system effects
Dermal Toxicity: May cause skin irritation, especially after prolonged contact
Chronic Effects: Prolonged or repeated skin exposure may lead to sensitization or dermatitis
Symptoms of Overexposure: Eye and skin redness, itching, headache, drowsiness from methanol vapor
Carcinogenicity: No component known to be carcinogenic at present concentrations
Mutagenicity: No evidence from available data
Reproductive Toxicity: Methanol release considered toxic to reproduction at high exposures
Other Health Effects: Pre-existing skin, eye, or respiratory conditions may worsen with exposure

Ecological Information

Ecotoxicity: Moderately toxic to aquatic organisms; avoid product release into watercourses
Persistence and Degradability: Undergoes hydrolysis in water to silanols and methanol; breakdown products biodegradable
Bioaccumulation: Low potential due to rapid hydrolysis and metabolism
Mobility in Soil: Hydrolyzed product is mobile in water
Other Adverse Effects: Uncontrolled release may impact aquatic life through oxygen depletion and organic load; avoid large-scale discharges

Disposal Considerations

Waste Disposal: Dispose of in accordance with local, regional, and national regulations; incineration or chemical treatment preferred
Contaminated Packaging: Empty containers may retain product residues; triple rinse and dispose as hazardous waste
Other Disposal Notes: Do not pour product or rinseate into drains, soil, or water bodies; consult licensed waste disposal contractor for bulk quantities
