I had an major over supply of people at training one night, and had six go out on an appliance, and the other 7 in the radio room, with each one scribing. The crews on the appliance went to an incident where a car had colliding with an LPG cylinder (one left out for the gas people to collect, as is not uncommon in the area), and the car collided with a tree, with the driver fleeing.
We asked that the Incident Controller provide very regular sitreps (almost a step by step guide to what the crew was doing), so that the scribes could practice scribing....since all of the scribes were usually fire fighters, it made them appreciate what it was like being on the receiving end of sitreps etc. We also discussed with them what other information they perhaps needed to ask for etc
Then we swapped the crews over, and did the same exercise.
While in reality, the incident controller provided far more information that what they would (or should) normally give, it gave the scribes practice in taking information, and writing it down......
But,as yet, there is no scribes course, or radio operators course, so it is (unfortunately) up to brigades to do their own thing with the training..
