Bill it may be standard stowage for CFS RCR but O2 is not listed in the equipment list in the Road Crash Rescue directory. And this is the "bible".
And why should it? RCR brigades/units/teams role in life is to provide a Rescue capability, not be a "super team" that does everything!
Last time I looked into a SAAS bus they carried all of that stuff & based on recent events they would be paged to a RCR job before rescue, so why carry gear you don't need! It's just more training & maintenance you need to do.
On the other hand ask yourself why Inland marine don't carry O2? Would have thought the need was greater. If you want to take on the Paramedics job as well become a community responder unit for SAAS & all of the training & equipment needs would be coveeed by them
I think it's about time that CFS & it's people start looking at every wildfire enquiry in Australia since Ash Wednesday. Hidden in the pages somewhere is a recommendation that the Lead agency for wildfire (CFA,RFS,CFS)needs to focus on their core business - combating wildfire! Thats why in the states that have tried to combine their emergency services, there is still a volunteer "bush" fire brigade.
So in my humble opinion stop worrying about some piece of gear that someone else has (& something we have never missed) & just focus on what you have got & need.
