I'm relatively new, I only joined CFS Feb last year, and I've been finding things that I merely don't know how to do, or how to do properly.
I personally think burn offs should be trained in an official capacity, maybe with the Suppress Wildfire, or even a separate course. I was taught how to do it by a member of my brigade, at a burn off we conducted, even though this was alright, I just think it should be done on a more professional level, and so that there's proof you're competent on what to do.
