I have a cousin that worked a metro fire department including paramedic most of his life.
Explained that they carried a big scoop shovel to clean up the really messy ones. He said it’s bad when the decomposed body seeps through the hardwood floor and through the ceiling of the apartment below.
Not a job for me!
I’m in awe of people like your cousin. I don’t know how they do it. I’d be traumatized forever.
