Ingestion: Rinse mouth; do not induce vomiting; seek medical advice immediately
Most Important Symptoms: Irritation, redness, itching, blistering of skin, eye watering, potential allergic response after skin exposure
Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide; water spray for larger fires
Unsuitable Media: Direct water stream may spread fire or cause foaming
Specific Hazards: Combustion generates toxic fumes like carbon monoxide, carbon dioxide, and methacrylate vapors
Protective Equipment: Full firefighting gear including self-contained breathing apparatus; evacuate area and fight fire from safe distance
Special Procedures: Cool containers with water if exposed to heat; avoid breathing fumes; container rupture possible under fire conditions
Personal Precautions: Wear chemical-resistant gloves, safety goggles, and protective clothing; ventilate area; avoid breathing vapors
Environmental Precautions: Prevent entry into sewers, watercourses, or soil; notify authorities if significant release occurs
Methods for Containment: Absorb spill with inert material like sand or clay; transfer residue to closed, labeled containers
Cleanup: Use non-sparking tools; wash area thoroughly after material pick-up; dispose of contaminated materials properly
Decontamination: Wash hands and exposed skin after handling; remove contaminated clothing and launder before reuse
Handling: Keep containers tightly closed; provide local exhaust ventilation; avoid contact with skin and eyes; do not inhale vapors
Storage Conditions: Store in cool, dry, well-ventilated location away from heat, sparks, flames, and incompatible materials like strong oxidizers or acids
Technical Measures: Use only with equipment resistant to methacrylates; keep container stabilized with recommended inhibitors
Incompatibility: Avoid contact with oxidizing substances, reducing agents, bases, and UV light
Storage Life: Observe shelf-life information supplied by manufacturer; heat and sunlight accelerate inhibitor exhaustion
Engineering Controls: Local exhaust ventilation, eye wash facilities, emergency shower
Occupational Exposure Limits: No established exposure limit for this compound; use general methacrylate guidance where local rules exist
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or butyl rubber), splash-resistant goggles, flame-retardant clothing, closed footwear
Respiratory Protection: NIOSH-approved respirator for organics if ventilation is insufficient or vapor concentration exceeds recommended levels
Hygiene Measures: Do not eat, drink, or smoke when handling; wash up after use; keep work clothing separate
Appearance: Clear, colorless to pale yellow liquid
Odor: Mild, acrid, acrylic-like
Odor Threshold: Not established
pH: Not applicable
Melting Point: Below 0°C (solidifies at low temperatures)
Boiling Point: Around 75–90°C at 1.01 kPa (depolymerizes upon heating)
Flash Point: 103°C (closed cup); combustible
Evaporation Rate: Not available
Flammability: Moderate; can form vapors that ignite at high temperatures
Vapor Pressure: 0.05 mmHg at 20°C
Vapor Density: >1 (air = 1)
Relative Density: 1.09–1.12 g/cm³ at 20°C
Solubility: Miscible with water, alcohols, many organic solvents
Partition Coefficient (log Kow): Estimated 0.8–1.0
Decomposition Temperature: Above 200°C
Viscosity: 8–15 mPa·s at 20°C
Chemical Stability: Stable under specified conditions with inhibitor present
Instability Temp: Polymerizes with heat, light, peroxides, or absence of inhibitor
Conditions to Avoid: Heat, flames, UV light, contact with peroxides, absent inhibitor
Incompatible Materials: Strong oxidizers, reducing agents, acids, bases, free radical initiators
Hazardous Decomposition: Generates carbon monoxide, carbon dioxide, and irritating acrylate fumes during combustion
Hazardous Polymerization: May occur with heat, contamination, or loss of inhibitor; uncontrolled polymerization releases heat and gases
Acute Toxicity: LD50 (oral, rat) 5,000–8,000 mg/kg; LD50 (dermal, rabbit) >2,000 mg/kg
Skin Corrosion/Irritation: Causes reversible skin irritation; repeated contact can cause dermatitis
Serious Eye Damage/Irritation: Moderate to severe irritation, redness, tearing
Respiratory Sensitization: Can trigger asthmatic symptoms, coughing in sensitive individuals on prolonged exposure
Carcinogenicity: Not listed by IARC, NTP, OSHA as a known carcinogen
Mutagenicity: No conclusive data on genetic toxicity
Reproductive Toxicity: No evidence of reproductive effects from available studies
Target Organ Effects: Eyes, skin, mucous membranes; allergic reactions possible
Aquatic Toxicity: LC50 (fish, 96h) estimated >100 mg/L; EC50 (daphnia, 48h) >100 mg/L
Persistence and Degradability: Expected to be readily biodegradable in the environment
Bioaccumulative Potential: Low log Kow suggests minor bioaccumulation hazard
Mobility in Soil: High due to water solubility; may migrate through soil into groundwater
Other Adverse Effects: No data on ozone depletion or specific long-term environmental impacts; inappropriate disposal threatens aquatic organisms
Waste Disposal: Incinerate in certified facility with pollution control; small quantities absorbed on inert material and land-filled as permitted by local laws
