How many Firesafe™ devices can be fitted into an oxygen circuit and where should firebreaks be installed?

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 on the cannula tubing close to the chest. FCV_FAQ.pdf
