Outdoor Warning System Test Friday at 2:30 p.m.

UT Tyler will conduct the monthly test of its outdoor warning system at about 2:30 p.m. Friday, May 1, 2009. The test will begin with a voice message, followed by a series of tones, and conclude with another voice message.

The outdoor warning system allows for both tone and voice alerts to the campus and will be activated whenever there is an immediate danger to the UT Tyler campus. When the sirens are activated, people are encouraged not to call the University Police Department, but to move to a safe place and obtain further information which will be released by text and e-mail messages, the University web site, and the media.

The test will last for approximately two minutes. In the event the National Weather Service issues watches or warnings for Smith County during the time period of the test, the system will not be tested.

UT Tyler Urges Campus to Take Flu Precautions

The University of Texas at Tyler encourages all members of the campus community to follow several simple measures to reduce the possible transmission of all flu viruses:

• Cover your nose and mouth with a tissue when you cough or sneeze.
• Wash your hands often with soap and water, especially after you sneeze. Alcohol-based hand cleaners are also effective.
• Avoid touching your eyes, nose, or mouth.
• Try to avoid close contact with sick people.

Symptoms of swine flu are similar to seasonal flu, including fever, cough, sore throat, body aches, headache, chills and fatigue. Seek medical attention early, as medications may help reduce the severity of the illness. If you are sick with influenza, you should stay home from work or school and limit contact with others to keep from infecting them. The majority of the patients with this flu have reported that the symptoms are mild and they have recovered fully.

For more information about swine flu go to http://www.cdc.gov/swineflu/
