Title: Firehouse exhaust system

Abstract: An exhaust recovery system vents exhaust from an exhaust pipe of a vehicle, located in an enclosed structure, as the vehicle is driven out of the structure. The system includes a coupling attached to a detachably connectable coupling support assembly to support the coupling proximate the vehicle exhaust pipe. An elongate flexible hose has a first end and a second end, where the first end of the hose is connected to the coupling. The second end of the hose is connected to an extendable assembly. A first member is interconnected between the support assembly and the extendable assembly that when tensioned as a result of the vehicle being driven out of the structure extends the extendable assembly. A second member is interconnected between the support assembly and the extendable assembly that when tensioned provides a force sufficient to detach the support assembly from the vehicle, wherein the first member is tensioned prior to tensioning the second member as a result of the vehicle being driven out of the structure.
