Working in a Steel Mill in the 1920's was a Hot ,Dirty and Dangerous job and deaths happened all too often depending on the plant. which saw some massive strikes like the Pressed Steel car company
There was no Protective FR Fire Resistant clothing or OSHA to protect workers you where on your own.
So goes the story of a steel worker named Andrew Posey who was consumed in a fiery explosion of a ladle of hot steel at the USS Donora Works. in 1920 a recently returned WWI veteran whose job was that of a ladle stopper some one who controlled and inspected ladles . He had just climbed down into a ladle to check it when there was an explosion and he was instantly vaporized. with 3000 degree molten steel.

USS Steel who at the time had just gone thru a brutal labor strike out of sympathy took that steel which filled the ladle poured it into a mold and then buried next to the open hearth as a Memorial to Mr. Posey. but explorations have proven no steel in or under the grave .
It appears to be a Big Lie
Now I also heard story's of similar accidents at other mills like J&L where the family was given a small amount of steel from ladle a worker fell in and steel was just poured off over hill side since it was contaminated. and then years later when the steel was disturbed during a gas line install that's when the haunting s started in the old no 1# shop
This also appears to be a lie and just a made up story as well.
Why would a Steel Mills owners make up such a lie and story ? It was well known how little regard owners had for their workers back then and even now. Was it just Public relations to ease tensions? or was it a dastardly plan to quell the workers I think the latter because USS has a history of being a bad employer back then. Need I mention Homestead which wasnt all the long ago.
