Which of the following statements about fog-streams is MOST accurate?
A) Fog-streams may be used to cool the hot fire gas layer.
B) Fog-streams have the greatest reach of all fire streams.
C) Fog-streams are less affected by wind than are other streams.
D) Fog-steams have greater reach and penetration than broken-streams.

Question

Quizplus · Accepted Answer

Fog-streams are specifically designed to cool the hot fire gas layer by creating a fine mist that increases the surface area for heat absorption. This is a key tactic in firefighting, especially in enclosed spaces where lowering the temperature of the fire gas layer can significantly reduce the risk of flashover. The other statements about fog-streams having the greatest reach, being less affected by wind, or having greater reach and penetration than broken streams are inaccurate. Solid streams typically have the greatest reach, and all water streams can be affected by wind to varying degrees. Broken streams, which are larger droplets than fog, generally have better reach and penetration than fog streams due to their mass and momentum.
