NU Online News Service, May 20, 12:15 p.m. EDT

With forecasters predicting 15 named storms forming in the Atlantic basin between June 1 and Nov. 30, the Institute for Business and Home Safety (IBHS) has listed its top four myths in preparing structures for hurricanes.

Yesterday, NU Online News Service ran six IBHS-recommended safety tips (http://www.property-casualty.com/News/2010/5/Pages/IBHS-Top-Six-Ways-To-HurricaneProof-Buildings.aspx).

IBHS also warned about the following common safety myths that are ineffective in protecting structures, and can even cause harm to the buildings and the people within:

o Open windows on the leeward side of the house so the air pressure doesn't explode the building.

IBHS said it is almost impossible to know ahead of time which will be the leeward wall. Additionally, wind directions frequently change as a storm passes, IBHS said.

"Trying to open and close windows during the storm puts you next to glass that can break, causing injury," IBHS said.

Additionally, IBHS said wind-driven rain could enter via open windows, damaging belongings.

IBHS explained that normal leakage of air around windows and doors will tend to keep pressure in the building slightly lower than the atmospheric pressure caused by the storm outside.

o You only need to protect the openings facing the ocean or gulf.

Because hurricanes are a moving, rotating storm, IBHS said, winds can come from any direction. The best bet, according to IBHS, is to protect windows and doors on all sides of the building.

o Tape windows with a big "X."

IBHS said taping glass does nothing to address the main point of protection--keeping the glass in its frame and securely attached to the building.

o Leaning or pushing against a window or door that is being blown inward by wind pressure can help keep the window or door from breaking or opening.

Leaning against windows and doors increases the risk of injuries, IBHS said. Ensuring that doors are properly anchored should be done before a storm threatens, IBHS said.

The IBHS website, disastersafety.org, provides more information on ways to protect property during a hurricane and other high wind weather events.
