Cleanup Methods: Contain and absorb spill with non-combustible absorbent (sand, earth, vermiculite), collect for disposal in closed containers, decontaminate area with water and detergent, provide ventilation during cleanup
Handling: Use only in well-ventilated area, avoid breathing vapors and contact with skin or eyes, use tools and equipment rated for flammable liquids, ground and bond containers
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place away from heat, sparks, and ignition sources, keep away from incompatible materials such as oxidizers and acids, segregate from food and feedstuffs, clearly label storage area and containers
Occupational Exposure Limits: No established OSHA/ACGIH permissible exposure limits, recommend keeping exposure as low as possible
Engineering Controls: Use explosion-proof ventilation and local exhaust at processing sites
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene recommended), safety goggles or face shield, lab coat or chemical-resistant apron, flame-resistant clothing for larger scale use, respirator with organic vapor cartridge if ventilation inadequate
