Firesafe Nozzle Nipple Nut-and-Stem 'Christmas Tree' Adapter for Oxygen Tubing & Concentrators

How Firesafe Works: The Firesafe Nozzle is essentially a thermal fuse, comprising a spring loaded valve held open by a T-bar. The T-bar is situated downstream of the valve and supported by a fusible ledge of material. The Firesafe valve is actuated when the fuisble ledge softens as a result of heat from an approaching fire in the oxygen delivery tubing. Upon actuation the valve probe moves forward and an o-ring seals the valve, thereby isolating the oxygen supply from the fire.

Usage Information: It is recommended that at least two Firesafe devices are fitted to each oxygen delivery circuit. The first, either a Firesafe Nozzle or Firesafe Cannula Valve depending on your oxygen setup, should be positioned close to the source of supply; and the second, a Firesafe Cannula Valve, should be positioned close to the patient. The Firesafe Cannula Valve provides no protection if a fire burns through the oxygen delivery tubing upstream of the device.

Replacement Information: The Firesafe Nozzle is maintenance free and has an intended life of 8 years. Dispose of any Firesafe Nozzle 8 years after the manufacturing date engraved on the device. Once actuated, the Firesafe Nozzle cannot be reset and must be discarded.
