If a small lab fire occurs, which action is recommended?

• A. Suffocate the fire with a beaker and remove nearby flammable materials.
• B. Smother the fire with a cloth or towel.
• C. Evacuate the building immediately without attempting to extinguish.
• D. Call campus security.

Answer: (A)

When a small lab fire occurs, the aim is quick containment that minimizes risk to you while stopping the fire from growing. Covering the flame with a beaker acts as a temporary lid, which blocks most of the oxygen the flame needs to continue burning. At the same time, moving nearby flammable materials away removes potential fuel that could feed the fire and let it spread. This combination directly reduces both the flame’s oxygen supply and its fuel source, making it the most effective immediate action when the situation is small and you can do so safely. Smothering with a cloth or towel isn’t as reliable here because fabric can ignite or catch embers and can trap heat, putting you at greater risk. Evacuating immediately without attempting to extinguish is sensible only if the fire is too large or you cannot reach it safely; otherwise, containment and removing fuel are preferred to prevent escalation. Calling campus security is important for reporting and getting help, but it doesn’t address stopping the flame right away in the scene. If the situation changes and you’re trained, using an appropriate extinguisher would be the next step, but only if you can act safely.
