Breathing air warning system for aerials, aerial platforms, air trucks and C.F.R. vehicles keeps firefighters informed of the percentage of air remaining in a breathing air system from 100% capacity down to zero. A low warning flashes at 25% of maximum air bottle capacity and a 90 dB audible warning sounds at 20% of capacity. The audible alarm can be manually silenced but the visual warning will continue to flash until the air system is filled above the 25% level.
