My dad was a firefighter and showed me the various nozzles they used on the firehose. One of them worked kind of like this, except it sprayed out of the hose (obviously), and created a shield-like spray in front. It was used mostly for cooling down hot air and combustible gases. It also carried the benefit of soaking the corridors you were walking through. If you're caught in a blaze, nothing will help you, but for anything else, this would be pretty useful.
It also creates a strong draft from your back which can either be a good or bad thing depending on your goal (clear out smoke)
