Inhalation: Move person to fresh air promptly, ensure comfort, provide oxygen if breathing is labored, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with soap and water for several minutes, seek medical attention if irritation develops
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing, get immediate medical help for persistent discomfort
Ingestion: Rinse mouth, do not induce vomiting, give water to drink only if person is conscious, seek medical advice right away
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (not direct water streams)
Hazards from Combustion: Produces irritating fumes of carbon monoxide, carbon dioxide, possible acrid smoke during thermal decomposition
Special Protective Equipment: Firefighters should use self-contained breathing apparatus, wear suitable chemical resistant clothing
Advice: Move containers from fire area if safe, cool containers with water spray, prevent run-off from entering drains and waterways
Personal Precautions: Evacuate unnecessary personnel, ventilate area, use personal protective equipment such as gloves and goggles
Spill Cleanup Techniques: Absorb with inert material like sand or earth, collect using non-sparking tools, transfer to a suitable waste container
Environmental Precautions: Prevent material from entering water courses, drains, or soil, inform authorities in case of significant spills
Handling: Minimize vapor formation, avoid breathing vapors, handle only in areas with proper explosion-proof ventilation, avoid contact with skin and eyes, use non-sparking tools
Storage: Keep in tightly closed chemical containers away from heat, open flames, direct sunlight, and incompatible materials, store in a cool, dry, well-ventilated place, check for polymerization inhibitors, regularly monitor environment for signs of leaking or decomposition
Occupational Exposure Limits: No established threshold limit values; use general industrial exposure guidelines for acrylates
Engineering Controls: Use local exhaust ventilation, closed processing systems to limit exposure
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), goggles, protective clothing, and face shield if splash may occur
Respiratory Protection: Use approved organic vapor respirators if ventilation is inadequate
Hygiene Measures: Wash hands thoroughly after handling, keep contaminated clothing separate and launder before reuse

Viscosity: 5 mPa·s at 20°C
pH: Not applicable
Partition Coefficient (n-octanol/water): Estimated as log Pow = 0.3
Chemical Stability: Stable under recommended handling and storage, risk of exothermic runaway polymerization if exposed to heat, light, high temperatures, or mechanical shock
Incompatible Materials: Strong oxidizing agents, strong acids, bases, amines, peroxides
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, irritating acrylate vapors
Polymerization: Can occur violently without added inhibitors, keep stabilized during storage
Inhalation: Inhalation may cause respiratory tract irritation, coughing, headache, dizziness
Skin Contact: Causes moderate to severe irritation, can cause allergic skin reactions in sensitive individuals
Eye Contact: Produces severe eye irritation, redness, tearing
Ingestion: May cause digestive tract irritation, nausea, vomiting
Chronic Effects: May contribute to skin sensitization and dermatitis upon repeated contact
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA
Mutagenicity: No comprehensive data, structurally related acrylates may induce genetic mutations in some assays
Aquatic Toxicity: Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Expected to undergo biodegradation, but may persist in larger spills
Bioaccumulation: Low potential due to low log Pow
Mobility in Soil: Considered mobile, can leach into groundwater if not contained
Additional Information: Prevent release into the environment, avoid aerosol or bulk discharge into waterways
Waste Disposal: Dispose under local, regional, national regulations; incinerate contaminated absorbent material in approved facility
Container Disposal: Containers must be completely emptied and triple rinsed before disposal, never reuse unwashed containers for other materials
Recycling: Not recommended, chemical recycling streams require specialist handling
