Eye Contact: Immediately rinse eyes with clean, gently flowing water for at least 15 minutes, holding eyelids apart, consult a physician for persistent pain or redness
Ingestion: Do not induce vomiting unless instructed by medical personnel; rinse mouth and drink water if conscious, call a poison control center or physician promptly; never attempt to give anything by mouth to an unconscious person
Self-Protection for First Aiders: Use impermeable gloves, safety glasses, and respiratory protection if necessary; avoid direct exposure to spilled material
Suitable Extinguishing Media: CO2, dry chemical powder, foam, or water spray; avoid high-pressure water stream to prevent spread
Unsuitable Extinguishing Media: Direct water jet may cause splattering
Specific Hazards: Releases flammable vapors, can form explosive mixtures with air, burning creates toxic fumes including CO, CO2, nitrogen oxides, and silicon oxides
Protective Equipment: Firefighters must wear self-contained breathing apparatus and fully protective clothing; avoid inhalation of gases produced in fire
Special Procedures: Isolate area, remove containers from fire if it can be done without risk, use water spray to cool tanks exposed to heat, prevent fire water from entering drains
Personal Precautions: Evacuate unnecessary personnel, ventilate area, use appropriate respiratory protection, wear chemical-resistant gloves and goggles
Environmental Precautions: Avoid discharge into drains, sewers, streams, or soil; notify authorities in accordance with local regulations
Containment and Clean-up: Absorb spill with inert material (sand, earth, vermiculite); collect material in suitable chemical waste container, clean up residue with water and detergent, ventilate area until fully dry, dispose of in accordance with national and local regulations
Decontamination: Wash contaminated surfaces with detergent and water, ensure ventilation until dry before re-entry
Precautions for Safe Handling: Work in well-ventilated areas, avoid inhalation and contact with skin or eyes, do not eat, drink, or smoke while handling the product, use explosion-proof equipment where necessary, ground containers when transferring liquid
Conditions for Safe Storage: Store in tightly sealed original containers, in a cool, dry, well-ventilated area, keep away from sources of heat, ignition, and direct sunlight, segregate from oxidizing agents, acids, and foodstuffs
Technical Measures: Use local exhaust ventilation, ensure containers are clearly labeled, avoid contamination and accidental mixing with incompatible materials
Storage Temperature: Maintain below 30°C (86°F) for optimum shelf life; avoid freezing
Exposure Limits: No established OSHA or ACGIH exposure limits for the compound; monitor possible methanol release (TWA 200 ppm - OSHA, 200 ppm - ACGIH)
Engineering Controls: Use local exhaust ventilation to minimize airborne concentrations, install eyewash stations and safety showers in working areas
Personal Protection: Wear chemical splash goggles or face shield, use butyl rubber or nitrile gloves, wear protective clothing such as long-sleeve lab coats, use an approved respirator if vapor or mist is likely above recommended guidelines
