Ingestion: Do not induce vomiting; Rinse mouth with plenty of water if person is conscious; Seek immediate medical attention and provide SDS to medical personnel
Most Important Symptoms/Effects: Redness, irritation, itching, possible rash in exposed areas; Shortness of breath or coughing if inhaled
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, water fog, or foam
Unsuitable Media: Direct water jet on burning liquid can promote fire spread
Specific Hazards: Heated product may produce acrid smoke and possible release of carbon monoxide, carbon dioxide, acrylic monomers, and other toxic vapors
Protective Equipment: Firefighters need full protective gear including self-contained breathing apparatus
Special Procedures: Use water to cool fire-exposed containers; Prevent run-off from entering water systems or sewers; Remove containers from fire zone if safe
Personal Precautions: Evacuate unnecessary personnel; Wear appropriate protective equipment, chemical-resistant gloves, goggles, and clothing
Environmental Precautions: Prevent product from entering drains, surface water, or ground water
Spill Cleanup Procedures: Absorb spill with inert material such as sand, earth, or absorbent clay; Place in sealed chemical waste containers for proper disposal; Ventilate area well; Wash area thoroughly with detergent and water after collection
Handling: Wear personal protective equipment to avoid skin and eye contact; Work in well-ventilated areas; Keep containers closed when not in use; Avoid sources of ignition and static discharge
Storage Conditions: Store in a cool, dry, well-ventilated place away from sunlight, heat sources, or incompatible materials like strong oxidizers and acids; Keep container tightly closed; Use only containers approved for acrylic esters; Store away from reactive chemicals
Incompatibilities: Avoid alkaline and acidic conditions, oxidizing materials, free radical initiators
Exposure Limits: No OSHA PEL or ACGIH TLV for this specific product; Use values for similar acrylic monomers (< 1 ppm recommended guidance)
Engineering Controls: Use local exhaust ventilation or process enclosures to keep airborne exposure below recommended limits
Personal Protective Equipment (PPE): Safety goggles with side shields, butyl or nitrile rubber gloves, chemical resistant clothing, and face shield for large volume use

Other Chronic Effects: Long-term repeated contact may cause dermatitis, allergic reaction on skin
Ecotoxicity: Toxic to aquatic organisms; May cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Not readily biodegradable; Possible slow breakdown in water and soil
Bioaccumulative Potential: Potential for moderate bioaccumulation based on structure and log Kow
Mobility in Soil: Low mobility due to low water solubility
Other Adverse Effects: May affect water organisms like fish and daphnia; Avoid release to waterways and drains
