Now you've got e coli, covid 19 , potentially legionnaires disease
For example, in sewage, bacterial pathogens such as Salmonella typhimurium, Enterobacter spp. and Streptococcus faecalis can survive for over 100 days before seeing a 1 log10 reduction.
So you're real risk isn't in it being airborne so much has having it in all of your drains, nooks and crannies, you'll need to unbolt equipment from the floor to move it....what about people traffic---now it's everywhere!!!
I did my high school co-op at a sewage treatment plant--i cannot emphasize enough how dangerous a scenario this is
seriously-anything touching th floor in and around the area needs decontaminated and legally, I don't think you can have your regular employees do this work as the area is now a bio zone
