Notes to Physician: Treat symptomatically, monitor for delayed pulmonary effects, consider risk of chemical pneumonitis
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry chemical powder
Unsuitable Media: Do not use water jet, which can spread fire
Specific Hazards: Vapors may travel to ignition source, explosive mixtures with air, hazardous decomposition releases carbon monoxide, carbon dioxide, acetic acid, and possible carbonyl compounds
Protective Equipment: Wear self-contained breathing apparatus, full protective gear, approach fire from upwind
Special Procedures: Cool containers with water spray, prevent runoff to drains, stay clear of tanks subject to explosion
Personal Precautions: Evacuate area, eliminate ignition sources, provide adequate ventilation, use personal protection including gloves, goggles, and suitable respirator
Environmental Precautions: Prevent entry into sewers, basements, waterways; inform responsible authorities in case of large spill
Methods for Cleaning Up: Contain spilled material with non-combustible absorbents (sand, earth, vermiculite), collect and place into proper chemical waste containers, ventilate area, decontaminate spill site after material pickup
Handling: Work in well-ventilated areas, ground and bond containers and equipment to prevent static electricity buildup, avoid inhaling vapors and contact with skin or eyes, use explosion-proof electrical equipment, keep away from heat, sparks, open flames, or hot surfaces
Storage: Store in tightly sealed containers, keep in a cool, dry, well-ventilated area, maintain away from direct sunlight, acids, oxidizing agents, and foodstuffs, use inhibitor to avoid polymerization, segregate from incompatible materials, regularly inspect containers for leaks
Occupational Exposure Limits: ACGIH TLV: 10 ppm (TWA), OSHA PEL: 10 ppm (TWA)
Engineering Controls: Local exhaust ventilation, closed systems
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, flame-resistant clothing, appropriate respiratory protection if ventilation inadequate
Hygiene Measures: Wash hands and face after handling, take off contaminated clothing and wash before reuse, do not eat or drink in work area
