Cleanup Methods: Absorb spillage with non-combustible material such as sand or earth, collect into sealed containers for proper disposal
Reference to Other Sections: See exposure controls and personal protection and disposal considerations
Large Spill Response: Isolate area, use non-sparking tools, notify local authorities in case of significant environmental contamination
Precautions for Safe Handling: Use only with adequate ventilation, keep away from heat sources and ignition points, ground containers during transfer, do not breathe vapors or mists
Safe Storage Conditions: Store in tightly closed original container, cool and well-ventilated area, segregate from oxidizing materials, acids and bases
Incompatible Products: Strong acids, strong bases, oxidizers, strong reducing agents
Other Notes: Keep container upright, label storage area with appropriate warnings, use spark-proof tools and explosion-proof equipment
