Firesafe™ Cannula Valves and Firesafe™ Nozzles should be installed downstream (of the normal oxygen flow), between the humidifier and the patient. There are no other particular or special requirements when fitting Firesafe™ Cannula Valves/Firesafe™ Nozzles in an oxygen circuit with a cold water bubble humidifier.
The Firesafe™ Cannula Valve and Firesafe™ Nozzle have been carefully designed to minimise resistance to the flow of oxygen. Considering the worst case – an oxygen concentrator with a non-backpressure compensated flowmeter calibrated at atmospheric pressure. If two Firesafe™ valves were installed in series, at an oxygen flow of 5 l/min, the actual oxygen flow … Read more
Where an oxygen concentrator is being used, it is recommended to install a Firesafe™ Nozzle at the interface between with the concentrator oxygen outlet and the oxygen tubing to isolate the oxygen supply at source in the event of a fire. A Firesafe™ Cannula Valve should then be installed close to patient, normally at a position … Read more
No, this is a single use device, no attempt must be made to reuse the device on another patient or clean it internally. A mild soap solution may be used to clean the outside of the device taking care not to allow any liquid to enter either orifice.
No, it is not necessary to sterilise the Firesafe™ cannula valve or Firesafe™ Nozzle at any time and no attempt should be made to do so.

Yes, the Firesafe Cannula Valve can be fitted to the small bore oxygen tubing inlet, whether that is fed into the CPAP ventilator or into a port in the patient breathing circuit. The temperatures of the gas delivered are very low in comparison to the activation temperature of the valve, so there is no risk of it … Read more
The Firesafe™ Cannula Valve/Firesafe™ Nozzle comprises a spring loaded valve probe contained within a moulded housing. In normal condition the valve is held open by means of a T‐bar arrangement on the valve probe at the downstream end that sits on a fusible ledge. The valve is actuated when the fusible ledge softens as a … Read more
