5. Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam; water used as spray to cool containers
Special Hazards: Releases flammable vapors at moderate temperature, decomposition can generate nitrogen oxides and silicon oxides
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Specific Methods: Move containers from fire area if safe, avoid breathing decomposed vapors
Hazardous Combustion Products: Includes silicon dioxide, nitrogen oxides, carbon monoxide, carbon dioxide
Addition: Vapors may travel and flash back over considerable distance, so isolate area quickly

6. Accidental Release Measures

Personal Protection: Avoid direct contact, ventilate affected area, wear gloves, goggles, chemical apron
Containment: Stop leak if safe, use sand or inert absorbent (not sawdust or combustible material), block off drains
Cleanup Methods: Collect spillage using non-sparking tools, place in clearly labeled containers, seal tightly
Environmental Precautions: Prevent release into watercourses, notify environmental authority if large spill enters environment
Decontamination: Wash area with detergent and water after removal of bulk liquid
Incident Response: All responders require proper PPE, ban smoking or ignition sources near spill site

7. Handling and Storage

Precautions in Handling: Use only in well-ventilated areas, avoid splashing, never eat or drink nearby, refrain from prolonged skin contact, ground containers to avoid discharge
Storage Conditions: Store in cool, dry, and well-ventilated space, away from sources of ignition, heat, or direct sunlight, maintain original packaging tightly closed
Incompatible Materials: Acids, bases, oxidizing agents, moisture which can hydrolyze silanes to ethanol
Special Requirements: Secondary containment for drums, storage below 30°C, periodic inspection for leaks
Storage Life: Stable for 12 months under recommended conditions, mark stock with receipt and expiry dates

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: Workplace limits for ethanol apply if hydrolysis occurs, follow country-specific OELs for similar silanes (often 10 ppm TWA)
Engineering Controls: Use local exhaust ventilation, closed handling systems, source capture for mixing or blending
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile recommended), splash-resistant goggles, long-sleeved lab coat or disposable coverall, closed-toe chemical-resistant footwear
Respiratory Protection: Suitable mask with organic vapor cartridge if airborne levels exceed exposure limits
Hygiene Measures: Wash hands before breaks and after finishing; avoid wipes with alcohol since this can increase skin absorption
Environmental Controls: Vent to scrubber or carbon adsorber before discharge, monitor for VOCs near processing points

9. Physical and Chemical Properties

Appearance: Clear, colorless to pale yellow liquid, moderate viscosity
Odor: Ammonia or alcohol-like, sharp impression
Odor Threshold: Noticeable at low concentrations, often below PEL

Melting Point/Freezing Point: Around -70°C
Boiling Point: 210°C (decomposes before reaching full boiling point for some variants)
Flash Point: 85°C (open cup, varies by composition)
Evaporation Rate: Slower than water, faster if hydrolyzed
Flammability: Flammable liquid and vapor
Explosive Limits: Not established for blend, ethanol content may lower LEL
