Hurricane Preparedness - Organized Preparation

Organized Preparation

Hurricane mitigation uses policies to make buildings and other infrastructure more resistant to the effects of tropical cyclones. In addition to facilities themselves being at risk, the internal contents of the structures can be damaged as result of exposure to water if the building envelope is breached, usually as a result of the strong winds associated with hurricanes and tropical storms. Although the negative pressure caused by high velocity wind flowing over a building roof can cause the roof to fail with the building envelope intact, broken windows allow the air pressure to rise inside a building, creating an even greater pressure difference, and increasing the likelihood of roof failure. This pressure increase results after an opening, that is, a window or door, is breached after being struck and broken by wind blown debris.

Famous quotes containing the words organized and/or preparation:

    Basically, I have no place in organized politics. By coming to the British Parliament, I’ve allowed the people to sacrifice me at the top and let go the more effective job I should be doing at the bottom.
    Bernadette Devlin (b. 1947)

    With memory set smarting like a reopened wound, a man’s past is not simply a dead history, an outworn preparation of the present: it is not a repented error shaken loose from the life: it is a still quivering part of himself, bringing shudders and bitter flavours and the tinglings of a merited shame.
    George Eliot [Mary Ann (or Marian)
