An airtight room and a volatile combustible liquid evaporating into that airtight room sound like a recipe for something bad.

I dunno. I still can’t get “explosion” from oily rags, gunpowder, primers, loaded rounds, etc. I could understand fire, but not explosion. Unless there was something in the room that I don’t normally keep.

I could go with that IF we knew what the Fire Chief identified as the explosive fuel and the source of ignition.

It takes a good bit of fuel evaporating to reach a lower explosive limit, unless of course the fuel is gasoline, propane or natural gas. solvents tend to make a brief flash fire and then a smaller Class A/B fire burns. They don’t often produce the high pressures of a gasoline vapor or propane/methane explosion. It just doesn’t read well.

I am really curious what the fuel REALLY was for this ‘explosion’. Spontaneously combusting rags do not an explosion make on their own.

The journalist here offered few clues.
