If there is any lesson to be learned from the one-two punch of national tragedies this week, it is this: life can go from comfortable to catastrophic in the blink of an eye.

That may not be a particularly reassuring thought, but local residents can take some comfort from the fact that Park City and Summit County officials have detailed disaster plans and conduct regular multiagency training sessions.

One of those exercises took place on Tuesday and, while that particular drill focused on preparing for a potential earthquake, it offered all of the participating entities valuable practice in communicating with each other and with citizens.

Park City's Emergency Management Plan is posted on the city's website, http://www.parkcity.org/index.aspx?page=83 , and is reviewed annually. Hugh Daniels, a former city councilor, serves as the city's emergency program manager. His responsibilities include coordinating equipment, personnel and training among city departments and working as a liaison with county, state and federal resources.

His counterpart at the County Courthouse is Kevin Callahan whose job, in addition to public works administrator, includes keeping the county's emergency plan and training up to date.

Both work closely with the county health department which offers a comprehensive home emergency planning guide for residents that can be found here:
