Environmental Precautions: Prevent entry into waterways, drains, or soil
Methods for Cleaning Up: Absorb spill with inert absorbent (e.g., vermiculite, sand), sweep up, place in suitable container for disposal, use spark-proof tools and explosion-proof equipment, decontaminate spill area with soap and water
Emergency Procedures: Evacuate area, eliminate ignition sources, notify relevant authorities if large spill occurs
Handling: Use proper ventilation, avoid contact with eyes or skin, do not breathe vapors, ground all equipment and containers, keep away from sparks and flames

Storage Temperature: Store at room temperature, recommended range 15–25°C
Special Requirements: Use explosion-proof refrigerators if refrigeration required
Exposure Limits: No established OSHA PEL or ACGIH TLV at federal level, use local country-specific guidelines, typical recommended value: 5 ppm TWA (workplace exposure limit)
Engineering Controls: Use fume hoods, local exhaust ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles, face shield, chemical-resistant clothing
Respiratory Protection: Use NIOSH-approved respirator for vapor exposure above recommended limits
