Were was your fire extinguisher.
Don't feel too bad. I was clearancing my case for the 2275 in my shop last week, very carefull to clean up the dust and chips from the case and workbench but forgot all the dust on my shirt, hit the stud insert with a sanding disc on my 90 grinder, shot sparks on my shirt and had a small magnesium fire on my chest
. So much for that shirt.
