It hit the shop which thankfully is not connected to the office.
It sounds like the fire originated under the hood of a tractor and spread to the ceiling. First responders called a second alarm and hazmat thanks to all of our... acetylene and propane tanks just being stored there. No injuries but I watched them work from home using my ip cameras setup to see what was going on with the news being too vague.
Looks like I lost my secondary MDF
I'll try and get some picturers tomorrow.
