The Australian Transport Safety Bureau advises that operators of transport category aircraft fitted with pressurised gaseous oxygen systems should consider the safety implications of these safety issues, with a view to ensuring that passenger briefings provide sufficient detail and instruction as to the functionality of the system and the actions necessary to appropriately activate the flow of oxygen.
