70% to pass

A high-velocity fog stream can be used in firefighting situations to drive heat and smoke ahead of the firefighters in a passageway. This technique should only be used when _______________.

A there is an outlet for the smoke and heat

B the fire is totally contained by the ship's structure

C at least two fog streams can be used

D using a 2-1/2 inch hose

AI Explanation

The correct answer is A) there is an outlet for the smoke and heat. Using a high-velocity fog stream to drive heat and smoke ahead of firefighters in a passageway is a technique known as "bleeding the fire." This method can be effective in controlling the spread of a fire, but it requires an outlet for the smoke and heat to be expelled. Without an outlet, the passageway could become dangerously superheated and filled with smoke, putting the firefighters at risk. The other options are not relevant to the specific use of high-velocity fog streams in this situation.
