They (FD) think it maybe was a gas leak in the parking lot, yet the injured suffered "propane flash" burns from inside the building.
And propane burns? One says they blacked out, yet they walked out of the building... ?
I've worked in large print shops I've never seen propane tanks there.
Is it possible there was a propane powered forklift in the building?
If there was a forklift chances are 99.9% it was propane. And the owners probably had a rack of spare tanks.
Paper dust is highly flammable ... electric fork trucks are a thing
Yes, every kind of dust can be explosive, even, although it doesn't seem there would be that much it might have contributed. How did the young men get "propane flash burns"? Not from Bic lighters.
It's possible...
Usually around paper and other combustibles they aren't allowed
If the building is built on a cement slab (most strip mall and factories are), then all electrical and gas must be ran above ground. If a machine or implement requires gas and it is located in the center of the building, then it will require a gas line to be ran overhead.
In my area we have natural gas, but rural areas around me have propane. Not sure what is the fuel of choice where this happened.
I previously worked in the propane industry doing safety inspections. I currently work in the manufacturing industry as a Environmental Health and Safety dude. Gas lines are not inspected as often as I think they should.
Thanks for the insight. 👍
