Are you good in bowling? Fire extinguisher balls have a lot of uses. They trigger when being in an open flame for 3-5 seconds. So you can roll/throw them into a fire from a distance, They can be dropped from a remote control multicopter. And, our main use, then can function as a guard. In an engine room or in our case if you fear that a still glimming fire might flame up again. So some hundreds of these balls are on small podests in the ash of the forest fire now.
Funny there are different shapes: football for US market, handball for europe, bowling if you can't throw but roll to the fire at long halls with a low ceiling, ....
Laws are a bit different from state to state and I live at a state border. On this site: If there is highest danger for forest fires smoking is not allowed beyond the warning signs. Anyone caught with a cigarette in a forest may be accused for tried negligent arson even the cigarette doesn't cause a fire. He may even get a ban, not allowed to enter the forest again.
