I came across this video for a neat looking product for fighting high rise fires from the floor below.
During the video we see how water can be applied through the device in either straight stream or via a remote controlled combination nozzle.
I have no opinion about the product positive or negative, that is not the reason for my sharing the video. As you watch, pay careful attention to the changes in smoke conditions between straight stream and fog.
Just in case you always wondered why there is more smoke when you use the fog nozzle as opposed to putting the fire out with the straight stream.

More reach, more water, less fire, less smoke.
