Specific Hazards: Combustion may release toxic vapors including nitrogen oxides and carbon monoxide
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Firefighting Procedures: Use caution, evacuate area, contain and cool containers exposed to flame with water spray
Personal Precautions: Evacuate area, ventilate, use personal protective equipment to avoid contact with skin and eyes, eliminate sources of ignition
Environmental Precautions: Prevent runoff into soil, waterways, and sewers; notify authorities if large deposits enter environment
Containment: Absorb with inert material such as sand or vermiculite
Cleanup Methods: Sweep or scoop up and place in a container for disposal according to local regulations, clean spill area with water and detergent
Handling: Wear chemical-resistant gloves, safety goggles, and appropriate respiratory protection, avoid breathing vapor or mist, use only in well-ventilated areas, ground containers to prevent static discharge
Storage: Store in tightly closed containers, away from sources of heat, sparks, or open flame, keep in a cool, dry place, segregate from oxidizers and acids, ensure secondary containment in case of leaks
Occupational Exposure Limits: No established limit for 1-vinylimidazole but minimize exposure as a precaution
Engineering Controls: Use local exhaust ventilation, closed systems, or other engineering controls to keep airborne levels low
Personal Protection: Chemical splash goggles, gloves, lab coat, flame-resistant clothing in high-risk situations, use respirators where adequate ventilation is not possible
Hygiene Measures: Wash hands after handling, do not eat or drink while using chemical, monitor workplace exposure if available
