Hazardous Combustion Products: Carbon oxides, acrid smoke, toxic fumes
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective gear
Specific Hazards: Polymerizes violently under fire conditions, sealed containers may rupture under heat, vapors heavier than air
Fire Precautions: Remove containers from fire area if safe to do so, avoid breathing combustion fumes, prevent run-off from entering drains or water bodies
Personal Precautions: Evacuate unnecessary personnel, keep away from open flames or heat sources, ventilate area, use eye and skin protection
Environmental Precautions: Prevent material from reaching drains, soil, or watercourses, use barriers or absorbent materials
Methods for Clean-Up: Contain liquid with inert absorbent (sand, earth, vermiculite), transfer to secured labeled containers for disposal, clean spill area using non-sparking tools, ventilate site
Additional Advice: Remove sources of ignition, report large releases as per local regulations, consult environmental agency for incident follow-up
Precautions for Safe Handling: Wear gloves, safety goggles, and protective clothing, ensure proper ventilation, avoid inhaling vapor or mist, keep away from ignition sources, implement local exhaust for high vapor areas
Advice on General Occupational Hygiene: Do not eat, drink, or smoke during handling, wash hands before breaks and after finishing work, maintain clean working zone
Conditions for Storage: Store in tightly closed containers, keep in cool, dry, well-ventilated environment, avoid temperatures above 30°C, store away from oxidizers, acids, alkalis, heat, UV light, and polymerization catalysts
Inhibitor Requirements: Maintain oxygen level in the container headspace, monitor inhibitor levels regularly, agitate material prior to use if stored for long durations
Special Packaging: Use polymerization-inhibitor lined drums or containers, avoid storage in aluminum or copper containers
Exposure Limits: Not established for 2-Hydroxyethyl Acrylate in most jurisdictions
Engineering Controls: Install local exhaust ventilation, ensure eyewash stations and emergency showers nearby, maintain low vapor levels
Personal Protective Equipment: Chemical-resistant gloves (nitrile, butyl rubber), splash goggles or face shield, long-sleeved lab coats or aprons, chemical-resistant footwear
Respiratory Protection: For low vapor concentrations, use appropriate organic vapor respirator; for high concentrations or accidental release, employ self-contained breathing apparatus
Hygiene Measures: Remove and wash contaminated work clothing, avoid skin contact or inhalation of vapors and aerosols, keep PPE in good working condition and replace as needed
