ok ...no place is going to clean mattresses in the kitchen if this is part of the kitchen..i played with the photo in paintshop and its on the inside of an outside brick wall next to a set of windows. it maybe vented to the outside and thats why it is on that wall.
a thought..many large "hospitals" had an on site farm..can,t see from the crud on the floor but they may have wheels food could be placed in them and sent out to the serving areas.after all this is a big place and with 3 meals a day you would need something large to move food and or trays drinking cups silverware to differnt places ...what the hell is this thing anyways!!!!!!
they look too small to put a mattress in to.they would clean the matterss in the laundery..and with no pipes or heating eliments,any that we can see in the photo.no dials or controls,they are open to the air so what ever was inside was not afected by being in the open air.they wouldn't keep animals in the kitchen area,chickens would be in a outside coop. eggs and such would more likely come from local farmers in the early years.i don,t think the head cook would let them have dead bodies to be in his kitchen lol..this just might be for dishes.
being that this was not a real hospital but a mental inst, from the size of this thing its not built like any autoclave i ever used. even the big one they used at the tb bulding years ago that i saw. this can't be an autoclave.but it could just be a locker for kitchen equipment to keep them out of the pt's hands. if this was in the kitchen
i work in a locked unit and we have many dementia pts. they do hold onto the bed rails in fear..tonight a pt came up to me grabed hold of my shoulders with a grip as if she was going to fall off a cliff.with tears in her eyes she opend her mouth as if to scream.but as hard as she could try she could not make a sound ,she was screaming in her mind but the pathway to vocalize it was gone.the sheer terror in her eyes at that moment as she looked at me ...i now belive there is a hell...i can,t even emagine haveing a pt go through something like that in a lonely steal cage.
