Concentration: 99% or higher for pure product, trace impurities such as water (<1%)
Impurities and Stabilizing Additives: No known significant effects except at concentrations noted
Inhalation: Move affected person to fresh air; keep at rest; seek medical help if symptoms like dizziness, headaches, nausea, drowsiness continue
Skin Contact: Remove exposed clothing; wash skin thoroughly with soap and water; seek medical attention if irritation persists
Eye Contact: Rinse eyes with plenty of water for several minutes; remove contact lenses after initial flush; seek help from eye specialist for persistent discomfort
Ingestion: Rinse mouth with water; do not induce vomiting; offer water if conscious; seek emergency assistance right away
Self-Protection for First Aiders: Always use gloves, protective eyewear; ensure adequate ventilation
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide; do not use direct water jet as it may spread fire
Specific Hazards: Forms explosive mixtures with air; vapor may travel far from spill; combustion gives toxic fumes of carbon oxides
Protective Equipment: Firefighters use full protective gear and self-contained breathing apparatus
Special Procedures: Keep containers cool with water spray; prevent runoff from entering drains, sewers, or waterways
Personal Precautions: Remove all ignition sources; ventilate area; wear chemical-resistant gloves, goggles, and suitable protective clothing
Environmental Precautions: Prevent entry into drains or waterways; alert authorities if spill reaches environment
Containment: Stop leak if safe to do so; absorb with inert material like sand, earth, vermiculite; use non-sparking tools
Cleanup: Transfer to sealed, labeled containers for disposal; wash area with water after material pickup
Safe Handling: Avoid inhaling vapors and contact with skin or eyes; use only in well-ventilated settings; keep away from heat, sparks, or flames; ground equipment to avoid static buildup
Storage Conditions: Store in tightly closed containers; keep in cool, dry, and well-ventilated places; separate from strong oxidizers, acids, or bases
Incompatible Materials: Strong oxidizing agents, acids, bases; reacts with certain plastics and rubbers
Storage Temperature: Ambient temperature ≤30°C
Occupational Exposure Limits: ACGIH TLV: 25 ppm TWA; OSHA PEL: Not established
Engineering Controls: Local exhaust ventilation or fume hoods to control vapor levels below exposure limits
Personal Protection: Splash-proof goggles, impervious gloves (nitrile or butyl rubber), flame-resistant clothing for large-scale use
Respiratory Protection: Organic vapor respirators for high vapor concentrations or inadequate ventilation
Hygiene Measures: Wash hands after handling, remove contaminated clothing, do not eat or drink in work area
