Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue rinsing, call poison center or physician
Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, seek emergency care
Medical Note: Treat as chemical burn, respiratory irritation can be delayed
Suitable Extinguishing Agents: Dry chemical, carbon dioxide, foam, use water spray for cooling containers only
Hazards During Fire: Release of toxic gases like hydrogen fluoride, boron oxides, carbon monoxide, and formaldehyde
Protective Equipment: Full protective clothing, self-contained breathing apparatus
Special Procedures: Avoid inhaling vapors, keep containers cool by spraying with water, prevent runoff into drains
Combustion Products: Toxic fumes including boron and fluorine compounds, formic acid, formaldehyde
Personal Precautions: Evacuate area, ventilate, avoid breathing vapors, wear chemical-resistant gloves and goggles
Spill Response: Absorb with inert material like vermiculite, collect spill in suitable container, wash spill site after material pickup
Environmental Precautions: Prevent entry into waterways, drains, soil, and sewers; notify authorities in event of large spill
Decontamination: Rinse area with large amounts of water, neutralize residue with sodium bicarbonate if possible
Waste Disposal: Dispose of in accordance with local, regional, and national regulation for hazardous chemicals
Handling: Only open containers in fume hood or ventilated area, minimize vapor generation, do not breathe vapor or mist, use spark-proof tools
Storage: Store in tightly closed, corrosion-resistant containers in cool, dry, well-ventilated area, keep away from heat, ignition sources, acids, and bases
Storage Conditions: Avoid direct sunlight, temperature extremes, label container clearly, store away from incompatible substances such as strong oxidizing agents and alkaline materials
General Hygiene: Wash hands and exposed skin after handling, remove contaminated clothing and gear before entering common areas
Incompatibilities: Acids, alkali, water, highly reactive with strong bases and oxidizers
Occupational Exposure Limit: BF3 TWA: 1 ppm (3 mg/m3), Methanol TWA: 200 ppm (260 mg/m3) as established by OSHA/ACGIH
Engineering Controls: Local exhaust ventilation, chemical fume hood, explosion-proof ventilation
Personal Protective Equipment: Chemical splash goggles, neoprene or nitrile gloves, flame-retardant lab coat, respiratory protection if airborne concentrations exceed limits
Hand Protection: Use double nitrile gloves for increased resistance
Hygiene Measures: Clean contaminated skin and change clothes after exposure, keep lab surfaces free from spills

Acute Toxicity: LD50 (oral, rat): Methanol 5628 mg/kg, LD50 (dermal): Methanol 15800 mg/kg, LC50 (inhalation, rat): Boron trifluoride 226 ppm/1h
Skin Corrosion/Irritation: Causes severe burns, redness, blistering
Eye Damage/Irritation: Permanent eye injury with direct contact
Respiratory Sensitization: Irritation, may cause Cough, bronchospasm, pulmonary edema
Chronic Effects: Chronic inhalation may affect liver, kidneys, central nervous system due to methanol
Carcinogenicity: Not classified by IARC, NTP, OSHA
Other Health Effects: May cause blindness or fatality if ingested; body absorbs methanol quickly, leading to toxic effects
Ecotoxicity: Very toxic to aquatic life due to methanol and boron content
Persistence and Degradability: Methanol degrades rapidly, boron compounds persist
Bioaccumulation: Low, methanol not likely to accumulate, boron may accumulate in plants and soil over time
Mobility in Soil: Methanol migrates easily, boron binds with soil particles
Other Effects: Release to waterways harms aquatic organisms, disrupts plant health, possible groundwater contamination
Waste Disposal Methods: Collect and label as hazardous chemical waste, incinerate at permitted site or dispose via licensed chemical waste contractor
Do Not: Release to environment, pour down drain or mix with household waste
Local Regulations: Follow all federal, state, and local hazardous waste disposal rules
Container Disposal: Rinse and puncture empty containers, dispose by incineration or designated landfill as hazardous waste
