This was some kind of processing building. Who knows what was done, there. No trespassing signs everywhere, nothing but weeds, nobody;s been in the building for years.

But the building had a special feature. Two walkways left the up-stairs rooms via outswinging doors to two galvanized steel escape slides.

The bottom of the slides look like this

The escape slides were so direct and so carefully constructed that it could only mean one thing: People had died, and they had done this to prevent a recurrence- or at least provide an escape route. Today it would be done by robots- or waldos. THen, it was done by humans. The slides say “When X happens, get the FUCK OUT IN A GREAT BIG FUCKING HURRY”.

I wonder what X was.
