First Aid Measures

Inhalation: Move affected person to fresh air. Keep at rest in comfortable position. Seek immediate medical attention if symptoms like coughing, shortness of breath, or dizziness develop. If breathing is difficult, oxygen may be administered by trained personnel.
Skin Contact: Remove contaminated clothing immediately. Wash skin thoroughly with soap and water for at least 15 minutes. If irritation or redness persists, get medical attention. Use lotion to relieve dryness.
Eye Contact: Rinse cautiously with clean water for several minutes, holding eyelids open. Remove contact lenses if present and easy to do. Continue rinsing and seek medical advice without delay.
Ingestion: Rinse mouth with water. Never induce vomiting except at the direction of medical personnel. If swallowed, seek medical care immediately and show product label or safety data.
Notes for Physician: Provide symptomatic treatment, monitor respiratory and skin reactions, and offer supportive care as indicated by clinical presentation.

Fire-Fighting Measures

Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or alcohol-resistant foam. Water spray can be used to cool containers but may be ineffective for extinguishing the flames directly.
Unsuitable Extinguishing Media: Straight water streams could spread fire. Avoid using high-pressure sprays.
Unusual Fire and Explosion Hazards: Vapors may form explosive mixtures with air; containers may rupture or explode from heat. Combustion produces toxic gases such as carbon monoxide and carbon dioxide.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, chemical-resistant boots, and full protective gear. Evacuate area and isolate hazard.
Special Procedures: Cool exposed containers with water spray even after fire seems controlled. Control runoff to prevent environmental contamination.

Accidental Release Measures

Personal Precautions: Evacuate non-essential personnel from area. Ventilate space thoroughly. Use personal protective equipment including chemical goggles, gloves, and respirators rated for organic vapors.
Environmental Precautions: Prevent entry into drains, sewers, or waterways. Contain spills with absorbent material like sand or earth.
Clean-up Methods: Collect liquid with inert absorbent and place in a suitable, labeled container for disposal. Scrub contaminated surface with detergent and water. Ensure safe disposal of clean-up waste.
Decontamination: Thoroughly wash skin and equipment in contact with the material. Decontaminate spills with soapy water and ventilate area.

Handling and Storage

Safe Handling: Use only in well-ventilated area, away from ignition sources. Do not eat, drink, or smoke during use. Avoid contact with eyes, skin, or clothing. Prevent formation of aerosols and vapor clouds.
Storage Conditions: Store in tightly closed, light-resistant containers at 2–8°C (36-46°F) in a dry, well-ventilated location, away from heat and direct sunlight. Separate from oxidizers, acids, and foodstuffs.
Packaging Materials: Use containers made of compatible materials such as stainless steel, glass, or high-density polyethylene. Check container for leaks before storing.
Transfer Precautions: Ground and bond all equipment to prevent static discharge during transfer.

Exposure Controls and Personal Protection

Exposure Limits: No established OSHA or ACGIH TLV values. Follow local regulatory limits if available.
Engineering Controls: Provide mechanical exhaust ventilation, eye washes, and safety showers at work stations. Maintain concentrations below exposure limits with adequate ventilation.
Personal Protective Equipment: Respirators with organic vapor cartridges, chemical safety goggles, nitrile or butyl rubber gloves, antistatic protective clothing, and chemical-resistant footwear.
Hygiene Measures: Wash thoroughly after handling, before breaks, and after shift. Remove and wash contaminated clothing separately from street clothes.
Monitoring Methods: Use workplace air monitoring devices to detect vapor concentrations. Keep exposure within recommended limits.

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling conditions. Unstable if exposed to open air, heat, or light for extended periods.
Hazardous Reactions: May polymerize violently in presence of free radical initiators, strong acids, bases, or heat. Risk increases under contamination with incompatible substances.
Conditions to Avoid: Keep away from excessive heat, moisture, sources of ignition, and incompatible chemicals. Air and sunlight accelerate polymerization.
Incompatible Materials: Strong oxidizers, acids, bases, reducing agents, and peroxides. Avoid contact with copper alloys, iron, and other metals that catalyze polymerization.
Hazardous Decomposition Products: Burning releases acrid smoke, carbon monoxide, carbon dioxide, and other unidentified compounds.
Polymerization Risk: High risk, especially without stabilizers.

Toxicological Information

Likely Routes of Exposure: Skin contact, inhalation, eye contact, accidental ingestion
Acute Toxicity: Dermal and inhalation exposure can cause irritation, sensitization, headache, fatigue, and respiratory symptoms. Oral toxicity data limited but ingestion may trigger nausea, abdominal pain, or more severe symptoms.
Skin Corrosion/Irritation: Causes redness, discomfort, or itching. Risks increase with repeated contact.
Serious Eye Damage/Irritation: Causes burning, watering, and redness. Can lead to temporary impairment.
Respiratory Sensitization: Prolonged exposure can aggravate asthma or respiratory sensitivity.
Chronic Effects: Repeated or long-term skin contact may cause sensitization and allergic reactions. No known carcinogenic effect based on animal data as of latest research.
Genotoxicity: Insufficient data for a definitive conclusion. Structurally similar acrylates have shown some positive results in laboratory studies.
Symptoms of Overexposure: Eye and respiratory irritation, skin dryness, headache, drowsiness, and potential chemical pneumonitis if large quantities inhaled.
Medical Conditions Aggravated: Pre-existing dermatitis, asthma, or allergic conditions may worsen with exposure.

Ecological Information

Aquatic Toxicity: Moderately hazardous to aquatic organisms according to experimental studies with structurally similar compounds. Avoid release to environment.
Persistence and Degradability: Likely to undergo slow hydrolysis in soil or water, forming less hazardous derivatives. Major breakdown usually by micro-organisms.
Bioaccumulation Potential: Not expected to bioaccumulate significantly based on structural analysis but data limited.
Mobility in Soil: Information limited, but as a low-water-solubility compound, risk for leaching appears moderate.
Other Adverse Effects: No evidence of persistent organic pollutant (POP) behavior. Take steps to minimize industrial runoff.

Disposal Considerations

Waste Disposal Methods: Collect residual material, contaminated absorbents, and wash waters in suitable sealed containers. Dispose of via a licensed hazardous waste disposal contractor.
Hazardous Waste Code: Check local, state, federal, and national hazardous waste regulations; this substance usually classified as hazardous industrial chemical waste.
Recycling/Recovery: Not considered practical at end-of-life; incineration under controlled conditions preferred.
