Small bench-top fires are common in labs, but large fires are rare. Labs using solvents pose risks of flash fires, explosions, and toxic smoke. Prevent fires by planning experiments carefully, minimizing hazardous materials, and keeping work areas clean and unobstructed.
Know your emergency equipment locations—fire extinguishers, alarms, emergency showers—and practice your response before an incident occurs.
If a fire occurs: + Rescue anyone in immediate danger. + Alarm others by shouting, pulling the fire alarm, and calling Public Safety. + Confine the fire by lowering the hood sash and closing lab and corridor doors. Secure experiments if safe. + Extinguish only if trained and safe, using an extinguisher or fire-resistant materials like a lid, fire blanket, sand, or baking soda. Otherwise, evacuate immediately.
Fire Extinguisher Tips: + Lab extinguishers are usually ABC dry chemical or CO₂, meant for small fires only. + They have a short spray duration (10–30 seconds) and short range (5–10 feet). + Always keep your exit behind you. + If unsure, evacuate immediately—your safety comes first.
Stay prepared and stay safe in the lab!
