A forest fire is one thing, its when you burn the building down with your hobby that is totally different. My store, business, shop are all located in my home, much like many of your hobby shops are. As much as I try to keep flamables contained and cleaned up, there is always an unsuspected pile somewhere. Hopefully the Carpenter Ants are gone, that pile looked to be fairly old, but it was hidden under a pile of junk and I have been aggresively attacking them this year.
When I did millwrighting at the sawmills, it was common practice to have a spotter under where you were working, and a security detail doing fire watch patrols all night. does not take much for a small ember to smoulder into a fire that will destroy a complete mill.
Yes Be Careful! Keep your eyes and nose open at all times when doing anything that creats sparks.
