Volunteers can be an incredible force multiplier in a disaster situation.  If leveraged properly, they can do wonderful things before, during, and after a disaster comes to your community...if not organized and managed, it can become a dangerous liability.  Work with partners in you community (churches, United Way, civic groups, etc) to ensure that you can safely, effectively, and efficiently on-board, utilize, and demob the surge of goodwill volunteerism when you need it most.
