Dear of troy: You mentioned a chute for trash. One big problem with chutes. The VA hospital where I worked had
chutes for linen to go to laundry. Some asshole efficiency idiot put a stop to washing fecally soiled sheets on the
wards, claiming it could be done more efficiently at the
laundry. A couple years later it was discovered that the
chutes were heavily coated with feces, and emitting huge
clouds of bacteria into the wards every time the chute doors
were opened.
