Well that sucks. Hope you had insurance.
You might be able to determine something about the sequence, from the damage to the wall. Presumably that plaster was removed from the wood lathes, by water-hosing? Since the timber is not charred. Also it didn't catch fire, luckily.
Are those portable benches the ones with molded plastic tops? Looks like a lesson there - don't use benches that melt and burn easily.
You have chairs identical to ours.
lot of the plaster damage is from FD tearing the plaster out to make sure fire had not got on the inside of the wall. FD Investigator says fire started in the right corner. which is where the solder irons sat. (thus my thinking the weller went nuclear)
and yes hard plastic top tables. and yeah 20/20 looking back not a good idea.
FD said the fire got very very hot. it was hot enough to start melting the glass in the window back side to the pic, also melted door curtain to the left into the glass.
FD had very good response time honestly. idk exactly when the 911 call went out to FD responding to FD arrive to FD putting water on it, but from what I was told it was a good response time.
above where it started was my shelf that i used to keep parts bins, solder rolls, flux, 99% iso, ect. I guess if the iso bottle melted and began leaking the iso that could have made the fire very hot real quick since it was a full big bottle i just got some weeks ago.
