      • Health Hazards: Causes serious, potentially irreversible, eye damage. Causes skin irritation and is a known skin sensitizer, meaning repeated contact can lead to the development of an allergic skin reaction (contact dermatitis). Vapors or mists may cause respiratory irritation.
      • Environmental Hazards: Harmful to aquatic life with long-lasting effects. Release into the environment should be avoided.
      • Reactivity Hazards: The product is a reactive monomer that can undergo hazardous polymerization if not properly stabilized and handled. Keep away from heat, sunlight, and contamination.
