In a rolled-over tanker fire, foam selection is based on identifying the

• A. Weather conditions
• B. Product on fire
• C. Location of the incident
• D. Time of day

Answer: (B)

Foam selection during a rolled-over tanker fire is driven by identifying the product on fire, because different fuels require different foam chemistries to be effective and safe. Knowing the fuel type tells you which foam concentrates are compatible and how they should be applied to create a stable blanket, suppress vapors, and provide cooling. Using the wrong foam can reduce effectiveness or even cause adverse reactions with certain products. Weather, location, or time of day don’t determine which foam to use; they influence tactics and constraints, but the fundamental choice of foam is based on the specific liquid involved.
