Impurities: Other acrylate compounds (trace), stabilizers (trace), residual monomers might appear in negligible concentrations from production
Additives: Stabilizers such as MEHQ may be included to inhibit polymerization during storage and transport
Inhalation: Move affected person to fresh air, maintain breathing, give oxygen if symptoms persist, seek medical attention if coughing or discomfort continues
Skin Contact: Remove contaminated clothing, flush skin with plenty of water for 15 minutes, clean with mild soap, seek medical attention if irritation or rash appears
Eye Contact: Rinse eyes with water for at least 15 minutes, keep eyelids open and move eyes in all directions, remove contact lenses if present, seek medical care if irritation persists
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, seek immediate medical attention, do not induce vomiting
Suitable Extinguishing Media: Water spray, foam, dry powder, carbon dioxide
Unsuitable Extinguishing Media: Water jet could spread chemical
Specific Hazards: Can form irritating fumes, carbon monoxide, acrid smoke, hazardous acrylate vapors when burning
Protective Equipment: Firefighters need self-contained breathing apparatus and full chemical protective clothing
Advice for Firefighters: Remove containers from area if safe, cool exposed containers with sprayed water, avoid runoff into drains
Personal Precautions: Use respiratory protection for high vapor levels, wear gloves and splash-proof goggles, avoid direct contact
Environmental Precautions: Keep out of waterways, prevent runoff into soil and storm drains, notify authorities about large spills
Containment Methods: Soak up with inert absorbent (sand, vermiculite), collect in closed waste containers
Clean-Up Methods: Ventilate area, wash residue with water and detergent, collect waste for approved disposal, avoid generating dust or mist
Handling: Use only in well-ventilated areas, ground containers to prevent static buildup, keep away from heat and open flame, avoid inhaling vapors, wash hands after use
Storage Conditions: Store in tightly closed original containers, cool and dry indoor location, keep away from sunlight and oxidizing agents, maintain temperature between 5°C and 35°C
Incompatible Materials: Strong acids, strong bases, oxidizers, reducing agents
Special Storage Considerations: Product can react with air over long periods, check for inhibitor presence in bulk containers, periodic agitation may prevent stratification
Control Limits: No OSHA-specific PEL, recommended workplace exposure level typically under 5 mg/m³ for aerosol or mist
Engineering Controls: Local exhaust ventilation, enclosed systems where practical, eye wash stations, safety showers in proximity
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety glasses with side shields or goggles, long sleeve clothing, apron or lab coat, respiratory protection if ventilation inadequate
Hygiene Measures: Avoid skin contact, wash hands thoroughly before lunch breaks or after handling, launder clothing before reuse
Form: Clear, colorless to pale yellow liquid
Odor: Mild, sweet acrylate
Boiling Point: 250°C at standard pressure
Melting Point/Freezing Point: -60°C
Vapor Pressure: Very low at ambient temperature
Flash Point: 115°C (closed cup)
Solubility: Low water solubility, mixes with most organic solvents
Viscosity: Ranges from 15 to 40 mPa·s at 25°C
Specific Gravity: 1.02–1.10
pH: Not applicable (non-aqueous)
Explosive Properties: Not classified as explosive, but vapors could form explosive mixtures when heated above flash point
Chemical Stability: Stable in sealed containers with added inhibitor (such as MEHQ), unstable on heating above 140°C or in direct sunlight
Hazardous Reactions: May polymerize violently without inhibitor or under extreme heat, exothermic reaction with peroxides
Incompatible Materials: Contact with strong acids, bases, and oxidizing agents can trigger hazardous polymerization
Hazardous Decomposition Products: Acrylate fumes, carbon monoxide, carbon dioxide, organic acids under fire conditions
Reactive Conditions: Prevent contamination with iron, copper, or moisture that could start unwanted reactions
Routes of Exposure: Skin, eyes, inhalation, ingestion
Acute Effects: Skin irritation, reddening, burning, eye irritation, upper respiratory tract discomfort
Chronic Effects: Potential for skin sensitization after repeated exposure, possible asthma-like symptoms in sensitized workers
Oral Toxicity (LD50): Estimated 5000 mg/kg in rats (low acute toxicity)
Inhalation Toxicity: Data suggests moderate risk if mist inhaled over prolonged periods
Dermal Toxicity: Moderate irritation, can cause allergic dermatitis in those predisposed
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, or OSHA
Mutagenicity: No substantial evidence from available studies to support mutagenic effects
Aquatic Toxicity: Harmful to aquatic organisms, acute EC50/LC50 for Daphnia and fish ranges from 1–10 mg/L
Persistence and Degradability: Not readily biodegradable, may persist several weeks in soil and water if released
Bioaccumulation Potential: Likely to have low bioaccumulation based on partition coefficient (log Kow ~3.2)
Soil Mobility: Weak binding to soil, risk of movement to groundwater in spills
Other Adverse Effects: High concentrations could cause oxygen depletion and physical smothering of aquatic life
Waste Treatment Methods: Dispose as hazardous waste, avoid landfill where mobile or free liquid, incinerate under approved conditions
Container Disposal: Empty drums and containers need triple rinsing and puncturing, disposal through licensed facility
Precautions: Consult local, regional, national, or international regulations before landfill or incineration
Do Not: Dispose via sewer, open land, or ordinary waste streams, avoid uncontrolled releases that enter watercourses
