Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses if easy to do. Continue rinsing. Seek prompt medical attention if irritation persists.
Skin Contact: Remove contaminated clothing. Rinse skin with plenty of soap and water. Seek medical advice if irritation or allergic reaction develops.
Inhalation: Move person to fresh air. Keep individual warm and at rest. If breathing is difficult, administer oxygen. Seek medical attention if symptoms do not resolve.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by a medical professional. Call a physician or poison control center immediately.
General Advice: Always consult medical personnel if you feel unwell or symptoms persist. Show this safety sheet to the doctor for reference.
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, water spray for larger fires.
Unsuitable Media: Direct water jets may spread liquid or increase risk of splashing.
Special Hazards: Emits toxic fumes of carbon monoxide, carbon dioxide, and oxides of nitrogen when burned.
Protective Equipment: Firefighters need full protective clothing including self-contained breathing apparatus.
Emergency Response: Evacuate area. Fight fire from a safe distance or exterior. Cool containers exposed to fire with water spray.
Hazardous Decomposition: Methacrylates, acrid smoke, irritating vapors under fire conditions.
Personal Precautions: Use personal protective equipment as described in exposure and protection section. Avoid breathing vapors. Stay upwind.
Environmental Precautions: Prevent runoff from entering drains, water courses, or soil.
Containment: Stop leak if safe. Contain spill using dikes or absorbent materials.
Clean Up Methods: Absorb with sand, earth, or a chemical absorbent. Shovel into containers for safe disposal. Wash spill site after material pick-up is complete.
Additional Advice: Remove ignition sources. Ventilate affected area. Dispose contaminated materials as hazardous waste.
Handling: Use with adequate ventilation. Wear appropriate personal protection to minimize exposure. Avoid static discharge. Keep containers tightly closed when not in use. Do not breathe vapors or get product on skin or in eyes. Wash thoroughly after handling.
Storage: Store in a cool, dry, well-ventilated area away from sources of heat, ignition, direct sunlight, and incompatibles (strong oxidizers, acids, bases).
Storage Temperature: Keep between 2°C and 25°C. Avoid freezing or overheating.
Incompatible Materials: Avoid contact with oxidizing agents, strong acids or bases, amines, free radical initiators.
Storage Containers: Store in original, properly labeled containers made with suitable chemical-resistant materials.
Exposure Limits: No specific occupational exposure limits set by OSHA, NIOSH, or ACGIH. Keep airborne concentrations as low as possible.
Engineering Controls: Use local exhaust ventilation. Enclose sources of vapor emission where possible.
Personal Protective Equipment (PPE):
Eyes: Chemical splash goggles or full face shield
Skin: Wear chemical-resistant gloves (nitrile or butyl rubber recommended), protective clothing
Respiratory: Use a NIOSH-approved respirator if ventilation is inadequate or exposure is over recommended limits
Hygiene: Wash hands thoroughly after handling and before eating, drinking, or smoking. Do not eat, drink or smoke while handling
