Skin Contact: Remove contaminated clothing, flush skin with plenty of water and soap, do not use solvents, seek medical attention for persistent irritation
Inhalation: Move person to fresh air, keep them calm and warm, ensure airway is clear, provide oxygen if breathing is difficult, seek medical assistance
Ingestion: Rinse mouth, drink plenty of water, do not induce vomiting, never give anything by mouth to an unconscious person, get medical help without delay
Symptoms of Exposure: Burning sensation, cough, sore throat, lung irritation, headache, abdominal pain
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, carbon dioxide, water spray for cooling containers
Unsuitable Extinguishing Media: Direct water jet may spread fire
Specific Hazards: Vapors may form explosive mixtures with air, exposure to heat can yield toxic silicon oxides and carbon oxides
Protective Equipment: Self-contained breathing apparatus, full protective suit for firefighting
Special Procedures: Keep away from ignition sources, use water spray to cool unopened containers, avoid breathing fumes, evacuate surrounding area as needed
Personal Precautions: Use suitable protective equipment, avoid skin and eye contact, ventilate area
Environmental Precautions: Prevent material from entering drains, waterways or soil
Containment Methods: Absorb spill with inert material like sand or earth, scoop up and deposit in properly labeled containers
Clean-Up Procedures: Wash contaminated surfaces with water and detergent, ventilate area thoroughly, dispose of collected material in accordance with local regulations
Handling: Take all precautions to avoid contact with skin, eyes, and clothing, ensure adequate ventilation or local exhaust at points of vapor generation, keep away from sparks and open flames, do not breathe vapors or mist, wash hands and face after handling
Storage: Store in tightly closed containers, keep in cool, dry, well-ventilated places, separate from acids, oxidizers, food, and beverages, protect from moisture to prevent hydrolysis, store below 30°C (86°F) if possible
Incompatible Materials: Acids, strong bases, oxidizing agents, water or moisture-sensitive substances
Exposure Limits: None established for the main ingredient; methanol release possible, observe OSHA, ACGIH, NIOSH limits for methanol
Engineering Controls: Local exhaust ventilation, closed systems where feasible, eyewash stations and emergency showers
Respiratory Protection: Approved respirator for organic vapors during aerosols formation or inadequate ventilation
Skin Protection: Chemical-resistant gloves, long-sleeved clothing, apron
Eye Protection: Safety goggles and face shield
Hygiene Measures: No eating, drinking, or smoking in work area, wash thoroughly after handling
Appearance: Clear to pale yellow liquid
Odor: Slight amine-like
pH: Not available (hydrolyzes in water)
Melting Point/Freezing Point: Below -40°C (-40°F)
Boiling Point: Approximately 254°C (489°F)

Partition Coefficient (log Pow): Not determined
Viscosity: Low
Chemical Stability: Stable under recommended storage conditions, decomposes on exposure to moisture, heat, or acids
Reactivity: Hydrolyzes rapidly in presence of water, releases methanol
Conditions to Avoid: Moisture, high temperatures, open flames, oxidizing conditions
Incompatible Materials: Strong oxidizers, acids, bases, water
Hazardous Decomposition Products: Methanol, silicon oxides, nitrogen oxides, carbon oxides
Polymerization: Not expected under normal handling and storage
Acute Toxicity: Oral LD50 (rat) estimated above 1000 mg/kg, harmful if ingested
Inhalation: Vapors cause irritation of mucous membranes and respiratory tract
Skin Corrosion/Irritation: Causes moderate to severe skin irritation
Eye Damage/Irritation: Causes severe irritation, risk of permanent eye injury
Chronic Effects: Prolonged or repeated exposure may cause dermatitis and sensitization
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA
Mutagenicity: Data limited, no evidence of heritable mutations
Reproductive Toxicity: Methanol, released on hydrolysis, known to damage organs and cause reproductive effects
Aquatic Toxicity: No specific data, methanol release can be toxic to aquatic life
Persistence and Degradability: Hydrolyzes readily, methanol degrades in the environment but poses risk short-term
Bioaccumulative Potential: Low for parent material, methanol can bioaccumulate in aquatic organisms
Mobility in Soil: Mobile due to solubility, risk of leaching to groundwater if spilled
Other Adverse Effects: Avoid uncontrolled release to the environment, monitor and follow best practices for chemical management
