I think your concerns about waste disposal are more than valid. If you’ve seen some of the reports from the Dallas invasion (yeah, I mean it), they have no idea how to deal with the contaminated apartment that Duncan lived in. Same thing happened with the waste generated in Emory University with Brantley. One report said so much waste was generated workers were sent to the local Home Depot to buy the largest trash cans and trash bags they could get to store the waste until the hazmat disposal company could come.
I understand flames work pretty well.
