This i know a little bit. No controlled burn/backburning near populated areas. Its usefulness is dwindling with more water bombers in the books.
I was on the backburn /helitorch team for 3 seasons, after my heart attack, standing under hovering helicopters was a bad idea. Too bad, that was the highlight of my government job.They wanted me to still participate,for the repair and fabricating part but its an all or nothing thing for me.
