Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing vapors, use protective equipment
Environmental Precautions: Prevent entry into sewers, storm drains, and surface waters
Containment Methods: Use inert absorbents such as sand, earth, or vermiculite to soak up liquid
Cleaning Up: Collect absorbed material into containers, dispose of in accordance with regulatory requirements, wash affected area with plenty of water
Handling: Use only in well-ventilated areas, avoid contact with skin and eyes, avoid inhaling mists or vapors, keep away from sparks and open flame, use static discharge precautions
Storage: Store in tightly closed original containers in a cool, dry, well-ventilated location, keep separated from strong oxidizers and acids, store away from incompatible substances, clearly label containers
Occupational Exposure Limits: No established TLV by ACGIH or OSHA, minimize exposure as a precaution
Engineering Controls: Local exhaust ventilation, eye wash stations, safety showers
Personal Protective Equipment: Chemical splash goggles or face shield, impervious gloves (nitrile or neoprene), chemical-resistant apron or lab coat, respiratory protection (in situations with inadequate ventilation or in case of spill)
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing and wash before reuse, do not eat, drink or smoke while working with the chemical
