Special Procedures: Cool exposed containers, avoid run-off into drains and waterways
Personal Precautions: Use appropriate protective equipment such as gloves and safety glasses, ventilate spill area
Environmental Precautions: Prevent spills from entering sewers, waterways, soil
Containment and Cleanup: Absorb with inert material like sand or diatomaceous earth, collect in chemically resistant containers, dispose according to local regulations, wash spill site with water and detergent
Handling: Avoid inhaling vapors or skin contact, use only in well-ventilated areas, wash hands thoroughly after use
Storage: Keep container tightly closed and stored in cool, dry, well-ventilated storage, protect from moisture and strong oxidizing agents, keep away from incompatible materials like acids and strong bases
Incompatibilities: Strong oxidizers, strong acids, and bases
Engineering Controls: Use chemical fume hood or adequate general exhaust ventilation
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), lab coat or apron, safety goggles or face shield
Respiratory Protection: Use approved respirator if vapor concentration exceeds exposure limits, especially under inadequate ventilation
Hygiene Measures: Wash hands and face before breaks and immediately after handling product, avoid exposure to open skin
