For a fuel spill measuring 4 ft by 7 ft, what is required?

• A. No action required
• B. Fire guard upwind with a foam-type or Halon-type extinguisher until inert
• C. Evacuate area
• D. Only a spill kit is needed

Answer: (B)

Flammable fuel spills demand immediate fire protection because vapors can ignite with little or no warning. A spill measuring 4 by 7 feet is large enough to create a significant vapour hazard, so you need active measures rather than passive containment. Set up a fire guard (fire watch) upwind so someone is positioned to detect any flame or flare‑ups and keep ignition sources away from the area. Have a foam‑type extinguisher or a Halon‑type extinguisher ready and use it if flames appear, continuing the effort until the fuel vapors have dissipated and the area is inert. Foam blankets the surface, cooling and preventing vapor from igniting, while Halon interrupts the chemical flame process. This approach addresses both ignition risk and vapor management, which a spill kit alone cannot do, and it avoids unnecessary evacuation when fire suppression can be successfully managed with the prepared protection in place.
