Personal Precautions: Evacuate area, ensure adequate ventilation, avoid contact with spilled material, use personal protective equipment
Environmental Precautions: Prevent further leakage or entry into drains, soil, and water sources
Containment and Cleanup: Absorb with inert material like sand or vermiculite, collect in suitable containers for disposal, clean spill area thoroughly
Safe Handling: Avoid exposure, use in well-ventilated areas, handle with care to prevent spills and splashes
Storage Conditions: Keep container tightly closed, store in a cool, dry, well-ventilated location away from ignition sources, segregate from incompatible materials such as oxidizing agents, acids, and water
Other Requirements: Keep away from food and drinks, use only equipment rated for flammable liquids, ground and bond containers and receiving equipment to avoid static discharge
Control Parameters: No established occupational exposure limits for this substance, observe general good industrial hygiene
Engineering Controls: Use local exhaust ventilation, maintain air concentrations below flammable limits, prevent accumulation of vapor
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, impervious clothing, respiratory protection for insufficient ventilation, eyewash station and safety shower should be accessible in work area

Likely Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Health Effects: Causes skin and eye irritation, inhalation can produce respiratory discomfort, ingestion may lead to gastrointestinal distress
Chronic Health Effects: Repeat or prolonged skin contact may cause dermatitis, no evidence of carcinogenicity or reproductive toxicity from available studies
Toxicity Data: Limited reported data; estimated oral LD50 (rat): >2,000 mg/kg
Sensitization: Low potential, though methacrylate esters may cause allergic skin reactions in sensitive individuals
Mutagenic Effects: No substantial evidence of mutagenicity in standard bacterial tests
Ecotoxicity: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Expected to hydrolyze and degrade slowly in natural conditions
Bioaccumulative Potential: Not likely to bioaccumulate due to hydrolysis and low log Kow
Mobility in Soil: Moderate mobility before hydrolysis
Other Adverse Effects: Avoid direct release into surface water, soil, and drainage systems, respect discharge regulations
Waste Disposal Methods: Dispose of in accordance with local, regional, and national regulations, do not discharge into drains, collect and send to an approved chemical disposal facility
Contaminated Packaging: Empty containers retain product residue (vapor or liquid), handle contaminated containers as hazardous waste until properly cleaned
Other Recommendations: Seek advice from chemical waste professionals, do not reuse containers for food or drink storage
