Which action is used to combat a Delta-fire?

• A. Firemain
• B. Halons
• C. Jettison
• D. CO2

Answer: (C)

Fighting a Delta-fire centers on removing the fuel source to starve the fire. A Delta-fire involves flammable liquids, so the fastest and most effective action is to jettison the fuel overboard or otherwise eliminate the fuel supply in the affected space. Once the fuel feed is cut off, you can apply suppression methods more effectively. Water-based suppression (firemain) can spread burning liquid and isn’t ideal for a fuel fire, while CO2 or Halons are better suited to enclosed spaces or other fire types and don’t directly stop the fuel source. By removing the fuel first, you reduce the burn and set up safer, more effective suppression afterward.
