Methods for Containment: Contain spill, prevent entry into waterways, drains, or soil
Cleanup Procedures: Absorb with inert material, collect in suitable containers for disposal, ventilate area, clean spill site thoroughly with soap and water
Emergency Procedures: Notify proper regulatory authorities if significant amount enters environment
Handling: Wear gloves, protective eyewear, and lab coat, use only in well-ventilated spaces, avoid splashing and generating aerosols, handle away from incompatible materials like strong oxidizers or bases
Storage: Keep container tightly closed, store in a cool, dry, well-ventilated area, keep away from heat or ignition sources, prevent buildup of vapors, label containers clearly, avoid storing with food or potable water
Engineering Controls: Use adequate local exhaust ventilation, maintain eyewash stations and emergency showers nearby
Personal Protective Equipment: Safety goggles, chemical-resistant gloves (nitrile or neoprene), protective clothing, in case of inadequate ventilation wear respiratory protection such as a NIOSH-approved respirator
