Impurities: Trace level byproducts of synthesis like mono- and diacrylate propylene glycol esters
Additives: Inhibitors (such as MEHQ) often present in minor amounts to suppress polymerization during storage
Inhalation: Remove victim to fresh air immediately, access medical help if symptoms develop or persist, support airway and breathing as required
Skin Contact: Remove contaminated clothing, wash affected skin with soap and water thoroughly, seek medical attention if irritation or rash appears
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, get prompt medical advice
Ingestion: Do not induce vomiting, rinse mouth with water if victim is conscious and alert, obtain medical help without delay
Important Symptoms: Redness, blistering or eczema at contact sites, respiratory irritation, burns
Notes to Physician: Symptomatic treatment, monitor for sensitization responses, supportive respiratory and dermal care
Suitable Extinguishing Agents: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray (do not use solid water stream)
Specific Hazards: Vapors may form explosive mixtures with air, heat can cause violent polymerization and container rupture, dense smoke or toxic fumes possible
Special Protective Equipment: Full protective gear with self-contained breathing apparatus recommended for firefighting operations
Firefighting Instructions: Keep cool with water spray, evacuate area, treat run-off as hazardous waste, non-essential personnel should avoid exposure
Personal Precautions: Evacuate unnecessary personnel, ventilate area, prevent skin and eye contact, avoid inhaling vapors
Protective Equipment: Nitrile gloves, chemical-resistant suit, goggles, respirator (if ventilation is inadequate)
Environmental Precautions: Prevent released material from entering drains, surface water, or soil, contain spill with absorbent material
Cleanup Methods: Contain and soak up with inert absorbents such as sand or earth, collect residues into suitable chemical waste containers, wash area with plenty of water and detergent
Safe Handling: Use only with proper ventilation, ground and bond containers when transferring, avoid direct contact and inhalation of vapors, keep containers tightly closed when not in use, avoid sources of heat and ignition
Storage: Store in original, tightly sealed containers in cool, dry, well-ventilated areas, keep away from oxidizers, strong acids, bases, sunlight, and ignition sources, monitor temperature and humidity, protect from moisture contamination
Special Considerations: Inhibitors present to prevent unwanted polymerization, regular checks on inhibitor levels recommended, keep storage areas clearly labeled
Occupational Exposure Limits: No official workplace exposure limits established, keep airborne concentrations as low as feasible
Engineering Controls: Local exhaust ventilation, safety showers, eyewash stations near work areas
Personal Protective Equipment: Chemical-resistant gloves (nitrile), impervious clothing, eye protection (goggles or face shield), certified respirator for inadequate ventilation or aerosol generation
Hygiene Measures: Wash hands, arms, and face after use, do not eat, drink, or smoke near handling area, remove contaminated clothing and launder before reuse

Chemical Stability: Stable under recommended handling and storage conditions, can polymerize exothermically with heat, light, or peroxides
Reactivity: Reacts with strong acids, bases, oxidizers, free radical initiators or UV radiation, may emit acrid smoke or irritating fumes on decomposition
Hazardous Polymerization: May occur under inappropriate storage, especially if inhibitor levels drop, or exposed to heat, sunlight, or contamination
Incompatible Materials: Strong oxidizing agents, reducing agents, peroxides
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, acrylic monomers, combustion byproducts such as irritating or toxic fumes
Acute Toxicity (Oral, Dermal, Inhalation): Low acute oral and dermal toxicity in animal studies, can cause irritation and sensitization after repeated exposure
Skin Corrosion/Irritation: Causes irritation and sometimes corrosive effects depending on duration and exposure level
Eye Damage/Irritation: Causes substantial eye irritation, risk of irreversible damage if contact is prolonged
Respiratory/Skin Sensitization: Known to cause allergic skin responses, rare respiratory symptoms in sensitive individuals
Chronic Exposure: Prolonged or repeated exposure can aggravate dermatitis, asthma, or eczema in sensitized people
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No evidence for carcinogenicity or significant mutagenicity in standard tests, reproductive effects not evident in current literature
Ecotoxicity: Toxic to aquatic organisms at high concentrations, may cause long-lasting harmful effects in water environments
Persistence/Degradability: Incomplete data, but evidence suggests moderate persistence, slow biodegradation in natural settings
Bioaccumulation Potential: Low-to-moderate, not expected to biomagnify significantly
Mobility in Soil: Low water solubility limits significant groundwater movement
Other Adverse Effects: Avoid discharge to surface waters, risk of localized ecosystem harm if released in large amounts
Waste Treatment Methods: Treat as chemical hazardous waste, do not allow into drains or water courses, use licensed professional waste disposal contractor
Container Disposal: Empty containers carry risk, do not cut or weld until thoroughly cleaned, follow local regulations for chemical containers
Special Precautions: Identify hazardous waste codes as set by local authorities, avoid landfill if possible, incineration preferred under controlled conditions
