Impurities: Typically contains traces of other acrylate monomers
Additives: Manufacturers may add small quantities of inhibitors to prevent unwanted polymerization during storage and shipping
Inhalation: Move person to fresh air, provide oxygen if breathing is difficult, seek medical attention if symptoms continue
Skin Contact: Remove contaminated clothing, rinse affected area with water and mild soap for at least 15 minutes, get medical help if irritation or redness appears
Eye Contact: Rinse immediately with plenty of water for a quarter hour, hold eyelids open to irrigate eye, remove contacts if present and easy to do, seek medical care without delay
Ingestion: Rinse mouth thoroughly with water, do not induce vomiting, call a physician immediately
General Advice: Take MSDS with you for reference in emergency room or with first responders
Suitable Extinguishing Media: Carbon dioxide, dry chemical, alcohol-resistant foam
Unsuitable Media: Direct water stream may spread burning liquid
Hazards from Combustion: Produces acrid smoke, carbon monoxide, carbon dioxide, possibly toxic acrylate fumes
Protective Equipment: Firefighters need self-contained breathing apparatus, full protective gear
Firefighting Instructions: Remove containers from fire zone if safe, cool exposed tanks with water fog, avoid breathing vapors, use shields from radiant heat
Personal Precautions: Evacuate non-essential personnel, ventilate area, remove ignition sources, wear gloves, goggles, protective clothing
Environmental Precautions: Prevent from entering soil, drains, waterways
Cleanup Methods: Contain with inert absorbent (sand, earth), collect in labeled disposal containers, wash spill site with water but prevent from entering drains, dispose of as hazardous waste following local, state, and federal regulations
Decontamination: Scrub small amounts with a detergent solution, avoid use of strong oxidizing agents which might cause rapid polymerization
Safe Handling: Operate in well-ventilated areas or established fume hoods, avoid skin and eye contact, use non-sparking tools, ground all equipment, prohibit eating, drinking, or smoking when working with this chemical
Storage: Store away from heat, sparks, open flame, direct sunlight, incompatible materials (acids, bases, oxidizers), keep containers tightly closed and in original packaging, maintain temperature below 25°C, use explosion-proof systems for quantity storage
Special Sensitivities: Monomer inhibitors added in container to prevent runaway reactions, check shelf stability regularly
Exposure Limits: No OSHA PEL or ACGIH TLV established, but handle as if a hazardous acrylate
Engineering Controls: Use ventilation such as local exhaust or fume hoods, process enclosure if vapor/mist present
Personal Protective Equipment: Chemical-resistant gloves (nitrile or butyl recommended), splash goggles or face shield, lab coat or coveralls, sturdy footwear
Respiratory Protection: Wear approved organic vapor respirator when exposure limits might be exceeded or when not adequately ventilated
Hygiene Measures: Remove contaminated clothing, wash hands and face thoroughly before breaks and after work, use safe storage for PPE

Reactivity: Can polymerize rapidly under heat, UV light, or in contact with peroxides or basic substances
Incompatibilities: Avoid contact with strong acids, strong bases, oxidizing agents, amines, reducing agents
Hazardous Decomposition: Releases acrid smoke, carbon monoxide, carbon dioxide during thermal decomposition
Hazardous Polymerization: May occur with elevated temperature or loss of inhibitor, polymerization can be violent
Likely Routes of Exposure: Inhalation, skin and eye contact, accidental ingestion
Acute Effects: Irritation of skin, eyes, and respiratory tract, possible allergic reactions on skin, mild toxicity if swallowed
Chronic Effects: Prolonged or repeated exposure may cause dermatitis or sensitivity, limited evidence for mutagenicity from some acrylate monomers, no known carcinogenicity
Acute Toxicity Ratings: Oral rat LD50 estimated above 300 mg/kg, dermal rabbit LD50 above 1,000 mg/kg
Effects of Overexposure: Headache, nausea, respiratory discomfort, skin eczema-like symptoms
Sensitization: Sensitizing to skin over repeated/prolonged exposure
Target Organ Effects: Skin, eyes, respiratory system
Ecotoxicity: Toxic to aquatic life with long lasting effects, short-term exposuress can harm fish and invertebrates at low concentrations
Persistence and Degradability: Degrades slowly in the environment, may bioaccumulate in some organisms
Bioaccumulation Potential: Moderate based on chemical structure
Mobility in Soil: Low due to moderate water solubility and tendency to bind to organic material
Other Hazards: Spillages into waterways cause oxygen depletion and toxicity to aquatic species, restrict release into natural water or soil
Waste Methods: Dispose by incineration at approved hazardous waste facility, follow EPA, local and state regulations
Container Disposal: Empty containers must be triple rinsed and punctured, do not reuse for any purpose, recycle or dispose as chemical waste
Sewage Disposal: Prohibited, do not allow into drains, surface water or soil
Special Considerations: Contaminated absorbents and cleaning materials require handling as hazardous waste
