Lets be realistic - the army - yea, for a CBR/terrorism incident yes - good call - but for a hazmat, forget it - the time it takes the squadron to be released to assist the civil community, travel, arrive and then set up, we can have the equipment that the two fire services have set up, used, packed up and going home.
WE (SA fire services) own similar mass casualty docon units to those used by the ADF and we have people trained in them - also MFS will send a team with it to assist in setting it up - it's not a big job and 4 people can do it in less an 20 mins - not allot of training requred either - just a good leader.
As for atmospheric monitoring - there are already brigades with the equipment and it's only a one day course!!!!
Once day it will be common - search the web, read some of the papers - if you knew what you were being exposed to at rural fires you would think twice, or in the area smoke (ie what falls out from the main plume)from a structure fire, bin fire, car fire and alike - atmospheric monitoring isn't hard and it's a great tool for all situations!
Steve if you guys at Eden want a good night - get Neil to approach Benrdon (Upper Sturt Capt) for an informative training night on atmospheric monitoring - it's definitely worth it and he knows his stuff - after all he is the accredited training provider
