Sodapop, as a cadet nurse in the mid 50's that was one of my jobs as well as using the autoclave for the metal bedpans where we had to make sure the door was properly secured or you ended up dressed in the contents.
When working on men's surgical one Christmas Day, I took a covered bedpan to be emptied and when I got in the sluice the chap had put a partly blown up green balloon in the bedpan and had bent it around the curve. At first I thought " oh God " then realised most of the patients had been in on the prank and I could hear the chaps laughing as I went back in the ward red-faced.
In actual fact, it wasn't a ward as we know them now, it was known as Hut 16, a disused, brick built Nissen structure as opposed to corrugated and I remember them being creepy places at night. I preferred the hospital wards and hated being sent to the huts. It was a hard job back then.
