I realize it which is why their strategy is a good one. Does it make sense for the people who are able to do that job also all be able to put out fires?
yes. they are edge cases but the training that comes with it translates fairly well to other tasks.
carrying grandma out of a burning building and carrying her downstairs after a fall are the same skill sets
I think someone that can carry grandma down the stairs and also occasionally put out a catastrophic fire is a pretty reasonable and efficient use of taxpayer money. The alternative would be what, having two different people to do those things?
