You know I’m not making an argument as there will be buildings that need to be saved for multiple reasons. However entry will require as noted a hazmat suit just to make an assessment. Then lots of disinfectant.
Just a note about tyvec suits: They tear relatively easy if they catch on anything. Additionally it’s important to have plenty of room in your suit. The crotch of the suit will rip out with little pressure. Move slowly and be aware of snags and tripping hazards. Quick forceful motion can tear the suit.
