What potential hazard should be anticipated after extinguishing a Type B fire?

After extinguishing a Type B fire, the chance of re-ignition is a significant hazard that should be anticipated. Type B fires typically involve flammable liquids, such as gasoline, oil, and solvents. When these types of materials are ignited, they can create large flames and significant heat, leading to the potential for residual flammable liquids on surfaces.

Even after the flames are extinguished, there may still be leftover vapors or ignitable materials that haven't been fully removed or dissipated. If the area is not properly cooled or if the environmental conditions change (for instance, if the area becomes disturbed), those residual elements can reignite, posing a serious risk. Therefore, it's essential for responders to remain vigilant and check the area thoroughly after suppression efforts to prevent a re-ignition scenario.

Other potential hazards, while important in their own right, do not specifically stem from the immediate aftermath of extinguishing a Type B fire in the same way re-ignition does.
