There are many detailed sources of information available online from government and non-profit agencies on how to survive and then deal with the aftermath of natural or manmade disasters. From how to prepare supplies for an impending event to the proper personal protective equipment (PPE) to use while cleaning mold out of a flooded building, dozens of relevant topics are covered in the following links.
Since some of the information you find on one site may be slightly contradictory to that found on another site, I would recommend using such information as a general reference while deferring to local standards. Specific information on clean up, disposal, and rebuilding procedures provided by your state, county, or municipality should be used as the tiebreaker, depending on whose jurisdiction a specific property address falls within.
There are more links within these links and some of them refer back to one another but I have listed the most relevant topics so you can use this page as a jumping off point for each topic and return to this page so you don't get lost layers deep within the links.
Note: Bold links contain the most comprehensive or valuable information.

Keep checking back for more coverage. Requirements of contractors that have been amended and even suspended by local and national building officials during this state of disaster are next followed by the account of one man's flooded workshop and what we learned about salvaging power tools and equipment. Also coming are reports on practical concerns to help contractors get on site and get to work such as dealing with roadblocks, insurance companies, and zoning regulations that may be subject to change due to the natural disaster.
This is the eighth in a series of reports intended to help inform both the victims of natural disasters as well as the contractors they look to in these times of crisis.
