Most Important Symptoms: Irritation, redness, allergic skin reactions.
Medical Attention: For severe symptoms or uncertainty, consult a physician promptly.
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide.
Specific Hazards: Emits toxic fumes under fire conditions, risk of vapor explosion.
Protective Equipment: Wear self-contained breathing apparatus and full protective gear.
Advice for Firefighters: Approach upwind, avoid run-off entering drains, cool containers exposed to flame with water spray.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, traces of other irritating gases.
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid inhalation of vapors and contact with skin.
Environmental Precautions: Prevent entry into sewers, surface water, or soil.
Methods for Cleaning Up: Contain spill using inert absorbent material (sand, earth), collect in suitable container for disposal, clean contaminated area with detergent solution.
Emergency Procedures: Use spark-proof tools, control sources of ignition, wear suitable protective equipment.
Reference to Other Sections: Use information in Sections 8 and 13 for further guidance on personal protection and disposal.
Handling: Use only in well-ventilated areas, avoid buildup of electrostatic charges, handle away from heat and ignition sources, avoid inhaling vapor or spray, avoid contact with eyes, skin, and clothing, keep containers tightly closed when not in use.
Storage Conditions: Store in cool, dry, well-ventilated place, keep away from sunlight and sources of ignition, store at temperatures below 35°C, use containers approved for flammable liquids, keep away from oxidizers and acids, ensure inhibitor remains present in storage to minimize polymerization.
Special Considerations: Regularly inspect containers for integrity, label containers clearly, maintain spill control resources nearby.
Exposure Limits: No specific occupational exposure limits set for IBOMA; keep airborne concentrations as low as practical.
Engineering Controls: Use local exhaust ventilation, explosion-proof ventilation for indoor use, ensure good general ventilation in the work area.
Personal Protective Equipment (PPE): Nitrile gloves, protective goggles or face shield, flame-retardant lab coat, chemical-resistant footwear.
Respiratory Protection: In case of insufficient ventilation or excessive vapor generation, use suitable respirator (organic vapor type).
