First Aid Measures

Inhalation: Remove to fresh air. If breathing is labored, provide oxygen. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing. Wash skin with soap and plenty of water. Do not use solvents. Get medical advice for signs of reaction.
Eye Contact: Rinse immediately with plenty of water, lifting upper and lower eyelids. Continue rinsing for at least 15 minutes and get medical attention.
Ingestion: Rinse mouth. Do not induce vomiting. Give water or milk if the person is fully conscious. Call a physician or poison control center.
Notes for Medical Staff: Treat symptomatically. No specific antidote.

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam and water spray
Unsuitable Media: Direct water jet (can spread material)
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, irritating acrylate fumes
Protective Equipment: Self-contained breathing apparatus and full protective gear
Special Precautions: Keep containers cool by spraying with water; keep away from combustible materials
Explosion Hazard: Material may self-polymerize and release heat

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel. Ensure adequate ventilation. Use recommended protective equipment (gloves, goggles, respirator).
Environmental Precautions: Prevent entry into drains, water courses, soil
Cleanup Method: Contain spillage. Absorb with inert material (sand, vermiculite). Collect in suitable, labeled containers for disposal. Decontaminate area with soapy water.
Disposal: Dispose of contaminated material through hazardous waste contractor

Handling and Storage

Safe Handling: Avoid contact with skin and eyes. Wear appropriate personal protection. Prevent inhalation of vapors or mists. Keep away from sources of ignition.
Storage Requirements: Store in tightly closed, light-resistant containers away from heat, sunlight and incompatible chemicals (oxidizers, free radical initiators, acids)
Incompatibilities: Avoid strong bases, acids, free radical initiators, peroxides
Technical Measures: Use only in well-ventilated areas.

Exposure Controls and Personal Protection

Occupational Exposure Limits: No regulated limits, follow general nuisance dust/vapor guidance
Engineering Controls: Use local exhaust ventilation to keep concentrations low
Respiratory Protection: Organic vapor respirators where vapor/aerosol risk exists; fit testing required
Eye Protection: Chemical safety goggles and face shields to prevent splashes
Skin Protection: Chemical-resistant gloves (nitrile, butyl rubber), coveralls, closed footwear
Hygiene Measures: Wash hands before breaks and after handling. Remove contaminated clothing before entering eating areas.

Toxicological Information

Acute Toxicity: No oral LD50 established for humans; low acute toxicity based on similar acrylates; potential for mild skin and eye toxicity
Skin Irritation: Causes irritation upon prolonged or repeated contact; can sensitize skin
Eye Irritation: Severe irritation, possible damage with direct exposure
Respiratory Effects: Irritation to nose, throat and lungs; possible allergic/asthmatic reactions in sensitized persons
Chronic Effects: Long-term overexposure may worsen skin sensitization; no conclusive evidence for carcinogenicity with this compound
Other Data: Not mutagenic or reproductive toxicant in standard tests; contains no known carcinogens as listed by IARC, NTP, OSHA

Ecological Information
