Geoffers: How do you mentor/supervise SPIFR ops? How do you sit next to a guy trying to refresh his/her skills with EMS?
Exactly - you can't. This is the problem...the ONLY way of assessing is by the back door - do some phoning around and learn about the individual before they take the reins.
If on the other hand one ends up with a dud - get rid!
[We don't want to end up like the US EMS fraternity now do we?]
