Other Information: Product contains no components considered hazardous according to established regulatory authorities at levels requiring disclosure under standard GHS criteria.

First Aid Measures

Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing eyes and seek medical attention if irritation persists.
Skin Contact: Rinse skin with soap and plenty of water for several minutes. Remove contaminated clothing and wash before reuse. If skin irritation or allergic reaction occurs, contact a physician.
Inhalation: Move affected person to fresh air. Provide oxygen if breathing is difficult. If symptoms continue, seek medical attention.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting. Never give anything by mouth to an unconscious person. Seek immediate medical attention.
Most Important Symptoms: Eye and skin burns, redness, irritation, allergic dermatitis, respiratory irritation, nausea if swallowed.
Immediate Medical Attention: Advise emergency responders of product identity and symptoms observed.

Fire-Fighting Measures

Suitable Extinguishing Media: Use water fog, alcohol-resistant foam, dry chemical powder, or carbon dioxide. Do not use water jet.
Specific Hazards: Vapor may form explosive mixtures with air. Containers may explode under fire conditions. Toxic gases such as carbon oxides and organic acids can form.
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective gear. Stay upwind. Avoid inhalation of combustion products.
Special Procedures: Cool exposed containers with water spray. Remove product from fire area if safe. Prevent fire runoff entering drains or waterways.
Explosion Data: Vapors may travel to source of ignition and flashback.

Accidental Release Measures

Personal Precautions: Evacuate non-essential personnel. Wear chemical-resistant gloves, goggles, and protective clothing. Ensure adequate ventilation in spill area.
Environmental Precautions: Prevent product from entering drains, waterways, or soil. Contain spillage with non-combustible absorbent material like sand or earth.
Cleanup Methods: Collect absorbed material with non-sparking tools. Store in labeled, sealed containers for disposal in accordance with local regulations.
Spill Reporting: Notify authorities if large spills enter environment.
Decontamination: Thoroughly wash contaminated surfaces with water and detergent. Properly ventilate area.

Handling and Storage

Handling: Work in a well-ventilated area. Avoid inhaling vapors, mists, or aerosols. Wear eye protection, gloves, and appropriate clothing. Do not eat, drink, or smoke during use. Ground containers to prevent static discharge. Use spark-proof tools and explosion-proof equipment.
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place away from heat, direct sunlight, and incompatible materials (like oxidizers, acids, bases, reducing agents). Keep away from ignition sources. Prevent polymerization by storing with recommended stabilizers at temperatures below 30°C.
Special Requirements: Regularly check containers for leaks and deterioration. Store away from food, beverages, and animal feed.

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific regulatory limits established for BDDMA. Limits for similar methacrylates suggest keeping airborne concentrations as low as possible.
Engineering Controls: Provide local exhaust ventilation, eye wash stations, and safety showers in working area.
Personal Protective Equipment: Use chemical-resistant gloves (nitrile), safety goggles, face shield, and suitable protective clothing. For high vapor concentrations or insufficient ventilation, use organic vapor respirator or supplied-air respirators.
Hygiene Measures: Wash hands after handling. Remove contaminated clothing before re-use. Do not eat, drink, or smoke where product is handled.
Environmental Controls: Use containment measures to limit environmental exposure.
