Firefighting Instructions: Cool containers exposed to fire, isolate area if possible, avoid inhaling fumes
Personal Precautions: Evacuate area, eliminate ignition sources, use proper protective equipment
Methods for Containment: Absorb with inert material (sand, earth), prevent runoff to waterways
Clean-Up Methods: Shovel soaked material into suitable waste containers, ventilate area, wash spillage with plenty of water
Environmental Precautions: Avoid discharge into drains, surface water, or soil, notify authorities if significant quantities enter surface waters
Handling: Keep container tightly closed, ground all equipment, handle in well-ventilated area, avoid ingestion or contact with skin and eyes
Storage Conditions: Store in cool, dry, well-ventilated place, away from heat, sparks, or open flames, store in original containers, prevent static electricity buildup
Incompatible Materials: Strong acids, strong bases, oxidizers
Safe Transfer Methods: Use spark-proof tools and explosion-proof equipment
Exposure Limits: Workplace limits are often not established but recommended not to exceed 50 ppm (vapor)
Engineering Controls: Ensure local exhaust ventilation at points of vapor generation
Personal Protective Equipment: Gloves made of nitrile or PVC, chemical splash goggles, impermeable clothing
Respiratory Protection: Use NIOSH-approved respirator if vapor levels are high or ventilation is insufficient
Hygiene Measures: Wash hands thoroughly after use, remove contaminated clothing, shower after handling large volumes
