Special Notes for Physician: Treat symptomatically, consider delayed pulmonary effects in cases of inhalation
Extinguishing Media: Use foam, dry chemical, carbon dioxide; avoid water jet as it may spread flames
Special Hazards: Gives off toxic fumes (carbon oxides, possible acrylic monomer vapors) in fire; container rupture due to high heat is a risk
Protective Equipment: Self-contained breathing apparatus for confined spaces, full protective gear
Fire-Fighting Instructions: Withdraw from area unless wearing specialized gear; use water spray to cool containers without direct stream on burning liquid; use explosion-proof equipment
Fire/Explosion Hazards: Vapors may travel to distant sources of ignition and flash back; container explosion possible
Personal Precautions: Evacuate non-essential personnel, ventilate area, eliminate ignition sources, use proper PPE (gloves, goggles, respirator)
Environmental Precautions: Prevent run-off to water bodies, contain with dikes or absorbent material
Clean-Up Methods: Stop leak if without risk, use inert absorbent (sand, earth), shovel into labeled containers, clean area with detergent and water
Special Considerations: Ensure all sources of static electricity are controlled, dispose of waste according to environmental regulations
Notification: Report spills as required to local authorities and company emergency contacts
Handling: Use in well-ventilated spaces, ground all containers and transfer equipment, avoid skin and eye contact, use spark-proof tools, protect from potential ignition sources
Storage Conditions: Keep container tightly closed in cool, dry, well-ventilated area; store away from oxidizers, strong acids, bases; avoid prolonged exposure to sunlight or heat
Special Storage Requirements: Store at temperatures below 30°C, with inhibitor present; check inhibitor effectiveness prior to storage over extended periods
Other Handling Practices: Wash hands after use, no eating/drinking in handling area, handle empty containers with caution; they may contain residues or vapors
Occupational Exposure Limits: ACGIH TLV: 2 ppm TWA (skin); OSHA PEL: not established for product; recommended limit: 5 mg/m³
Engineering Controls: Local exhaust ventilation, process enclosure, explosion-proof electrical systems
Personal Protective Equipment: Chemical-resistant gloves (nitrile, PVC), splash-proof safety goggles, flame-resistant lab coat, suitable respiratory protection for vapor exposure (e.g., organic vapor respirator)
Hygiene Measures: Remove contaminated clothing, wash thoroughly before eating or drinking, provide eyewash stations near work area
