Advice to Physician: Treat symptomatically. Watch for respiratory complications or delayed allergic skin responses.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray
Unsuitable Media: Do not use direct water jet, as liquid may spread and increase fire risk
Hazards from Combustion: Emits acrid smoke, carbon monoxide, carbon dioxide, possible formaldehyde on burning
Special Firefighting Procedures: Firefighters wear full protective gear, self-contained breathing apparatus. Cool fire-exposed containers with water spray to prevent rupture.
Unusual Fire/Explosion Hazards: Vapors heavier than air can travel along surfaces to distant ignition sources and flashback.
Specific Hazards: Heat or flames may cause pressurized packaging to rupture violently.
Flash Point: Approximately 96°C (open cup method reported)
Auto-Ignition Temperature: Not well-defined; keep away from ignition sources
Personal Protection: Ventilate area. Wear recommended protective clothing including gloves, chemical splash goggles, and respirator if exposure exceeds recommended limits.
Environmental Precautions: Prevent entry into sewers, drains, surface water, or soil. Collect spillage with absorbent material.
Containment and Clean-Up: Stop leak if safe. Use inert absorbents like vermiculite or sand. Scoop up using non-sparking tools. Dispose of according to local regulations.
Decontamination: Wash spill area thoroughly with water and detergent after removal of bulk material.
Special Procedures: Isolate hazard area, keep unnecessary personnel away. In cases of large releases, evacuate downwind areas.
Safe Handling: Use proper ventilation. Avoid inhaling vapor or mist. Prevent skin and eye contact. Handle away from sparks, flames, or excessive heat. Take precautions against static discharge.
Storage: Keep container tightly closed. Store in cool, dry, well-ventilated area. Avoid sunlight and extreme temperatures. Do not store with strong oxidizers, acids, or bases.
Incompatibilities: Strong oxidizers, strong acids, bases, amines, reducing agents
Other Precautions: Keep away from food, beverages, and animal feed. Keep container upright and secure.
Occupational Exposure Limits: No specific regulatory limits, treat as general methacrylate monomer
Engineering Controls: Use local exhaust ventilation or process enclosure to minimize exposure.
Personal Protection – Eye: Chemical safety goggles and face shield
Personal Protection – Skin: Impervious gloves, apron, and protective clothing
Personal Protection – Respiratory: Approved respirator for organic vapors and particulates if exposure exceeds limits
Personal Protection – Other: Always wash hands before eating, drinking, or using restroom
