Straight streams can be effectively used for foam application with:

Straight streams can be effectively used for foam application with:

• A. Aqueous Film Forming Foam.
• B. Compressed Air Foam Systems.
• C. Protein Foam.
• D. Film Forming System.

Answer: (B)

Straight streams move a lot of water quickly and can reach far places, but foam needs air to create a stable, thick blanket. Compressed Air Foam Systems inject air into the foam solution, producing a highly expanded, stable foam that blankets the surface even when delivered as a straight stream. That combination gives you both the reach of a straight stream and the effective foam coverage needed to cool and knock down the fire, with less water than traditional foam. Other foam types can produce foam, but their quality and stability aren’t as reliable with straight streams, making CAFS the best match for this delivery method.
