Stabilizing Component: Small percentage of polymerization inhibitor (such as MEHQ, 100–200 ppm)
General Advice: Remove from exposure. Seek medical attention if symptoms persist.
Inhalation: Move person to fresh air immediately. Monitor for respiratory irritation. Obtain medical attention if symptoms occur.
Skin Contact: Remove contaminated clothing. Rinse thoroughly with water and mild soap for at least 15 minutes. Get medical help if reaction or irritation develops.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, holding eyelids open. Remove contact lenses if present. Immediate medical attention required.
Ingestion: Rinse mouth. Do not induce vomiting. Give small quantities of water to drink. Seek prompt medical assistance.
Suitable Extinguishing Media: Water mist, foam, dry chemical, carbon dioxide
Unsuitable Media: Do not use direct water jet
Hazardous Combustion Products: Acrid smoke, carbon monoxide, carbon dioxide, irritating acrylate fumes
Special Protection for Firefighters: Full protective equipment and self-contained breathing apparatus are necessary
Fire/Explosion Hazards: Vapors heavier than air; may travel and flash back. Containers may rupture in fire.
Personal Precautions: Avoid breathing vapors. Wear protective equipment including gloves, goggles, and chemical-resistant clothing.
Environmental Precautions: Prevent entry into drains and surface water. Notify authorities if large releases occur.
Cleanup Methods: Contain and collect with inert absorbent (sand, vermiculite). Transfer to labeled disposal containers. Ventilate area. Decontaminate spill area with dilute sodium hypochlorite solution, followed by detergent and water.
Handling: Ensure good ventilation at workplace. Avoid skin or eye contact, inhalation of vapors or mist. Wear appropriate PPE. Use explosion-proof electrical devices where necessary.
Storage: Keep containers tightly closed in a cool, dry, well-ventilated area out of direct sunlight and away from heat sources or ignition points. Store away from oxidizers, acids, bases. Do not store near food or feed. Protect from freezing and moisture. Maintain temperature below 30°C (86°F).
Exposure Limits: No specific OSHA/ACGIH limits, minimize all exposures
Engineering Controls: Use local exhaust ventilation to reduce vapor concentrations
