Component: Butyl Acrylate
Concentration: >99%
Impurities: May contain trace inhibitors (like phenothiazine) to prevent polymerization
Other Ingredients: None listed in significant concentration
Inhalation: Move exposed person to fresh air without delay. Provide oxygen if breathing becomes difficult. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Seek medical help for persistent irritation.
Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes. Hold eyelids apart while flushing. Remove contact lenses. Get prompt medical evaluation.
Ingestion: Rinse mouth. Give water if the victim is conscious, do not induce vomiting. Get medical attention promptly.
Notes to Physicians: Treat symptoms. Watch for sensitization reactions.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (do not use heavy water stream)
Special Precautions: Vapors can form explosive mixtures with air. Use water spray to cool containers. Keep away from ignition sources.
Fire Hazards: Flammable liquid. Vapor may travel and ignite at distant locations. Fire may produce irritating fumes (carbon oxides, acrid smoke).
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear.
Personal Precautions: Evacuate unnecessary personnel. Provide ventilation and eliminate ignition sources. Use personal protective equipment.
Environmental Precautions: Prevent further leakage or spillage if safe. Avoid entry into drains, sewers, or waterways.
Cleanup Methods: Contain spill with inert absorbent material (sand, earth, vermiculite). Scoop into suitable disposal container. Flush area with water. Properly ventilate affected area and wash surfaces.
Safe Handling: Use in well-ventilated areas. Avoid inhaling vapors or contact with skin and eyes. Prevent static discharge by grounding equipment.
Storage Conditions: Keep in tightly closed containers, store in a cool, dry, and well-ventilated place. Store away from sources of heat and strong oxidizers. Protect from sunlight. Use inhibitors to prevent polymerization.
Incompatible Materials: Strong acids, strong bases, oxidizing agents, amines
Occupational Exposure Limits: OSHA PEL: None established; ACGIH TLV: 2 ppm TWA (skin)
Engineering Controls: Use local exhaust ventilation to minimize vapor exposure. Implement process enclosures where feasible.
Personal Protective Equipment: Chemical splash goggles, impervious gloves (nitrile, neoprene), flame-retardant and chemical-resistant clothing. Use NIOSH-approved respirators for high vapor concentrations.
Hygiene Measures: Wash hands prior to eating, drinking, and leaving work. Remove contaminated clothing.
