I think this may be the answer. I would have been concerned if they showed up on the street with their hazmat suits on. After all, we would expect those suits to be covered with questionable biological material. The best technique would have been to take them off prior to coming into a public, uncontrolled area.
The proper procedures for something like this has got to be a nightmare. Here's my first guess:
(1) don suits
(2) enter hazardous area with all equipment you are ever going to need unless you are able to pass things in from the outside and seal the apartment
(3) clean every surface which possibly could be contaminated while not spreading any contamination which might have accumulated on your suit (WOW!)
(4) establish a portable clean field by rolling out a fresh mat where everyone can stand
(5) clean your suit and equipment on the clean field
(6) take off cleaned hazmat suit for disposal while standing on the clean field
(7) someone still in a hazmat suit places discarded hazmat suit in a barrel
(8) last guy puts their own hazmat suit in barral
(9) roll up "clean field" and place in barrel
(10) seal lids on barrel and hope that nobody touched the outside with their hazmat suits prior to being sprayed down
(11) open the apartment
(12) carry the barrels out to the street in your street clothes
they didn’t clean because it wasn’t exposed to body fluids said some authority.

Yep. Unlike the cops that tossed their stuff in a street can.
