: Various times I have heard "Air" Units being dispatched to fires by the SFD. Today, I drove by Air 10, and it is not what I thought it was. What kind of units are the Air units?
Seattle Fire Air Units are the trucks that recharge the breathing apparatus taht firefighters wear when the atmosphere is hazardous.
From what Ive seen, I dont think they recharge the bottles with straight Oxygen, I have seen them unreel a large hose with an air cleaner on the end some distance from/upwind of the fire units and start their compressors.
I would think that using straight O2 would be very dangerous inside a fire.
