One thing movies never get right is sprinkler systems. Typically when they go off the water quality would not make you want to stick your tongue out. Here you can see that illustrated clearly. The operating room floor is grey but water that came out of the sprinklers stained it black in places.
When we got the call we extracted all the water, cleaned and sanitized all the surfaces including the floor. The stain and soil was no match for our product SERVPROXIDE.
