Tower rescue is a specialty within the vertical rescue domain. I'd doubt that many (if any) of the Emergency Services (possibly other than SAMFS) have the correct type of equipment and training to undertake it, as towers e.g. comms, power etc present unique hazards not associated with general rope rescue. As for Confined Space Rescue, RCR brigades are not equipped to deal with CSR. CSR is more aligned to Hazmat or USAR than RCR, prerequisites for CSR include CABA,Rope Rescue and Atmospheric Monitoring. The biggest misconception that some people have (including poster's on this thread) are to confuse Tower Rescue, Confined Space Rescue and Vertical Rescue with Working at Heights and Confined Space Entry. One level of training is to enable a user to conduct activities (work)in that discipline using a particular level of equipment and procedures, while the other focus's on Rescue from those activities using in most cases completely different equipment and procedures.
As for who should be doing the rescue's? The closest available resource who can commit to the undertaking the training, and maintaining the skills (it takes more than one training session a year to truly remain competent)irrespective of which agency they are.
And as for who can deliver this training? Sorry to respectively inform some of you its not SES (for a whole host of reasons, that should really be on another thread) and you probably wouldn't receive it from SAMFS, and since i'm not into using this place as an advertising endorsment is a company well known to nearly all poster's on here. And they deliver all of this training Australia wide to all Emergency Service agencies (Public and Industrial) in all states, and part of South East Asia as well
My thoughts only and possibly for the first time in history my only sensible post..
