Jefferson Lab's Monthly Tornado Warning Siren Test set for Sept. 7 at 10:30 a.m.

Posted Sept. 5, 2012

Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, Sept. 7. Depending on weather conditions at the time of the test, the siren may be heard by anyone outdoors within a 1.5-mile radius of the lab.

Don't respond to the siren; this is a test of the siren system and not a personnel response exercise.

The test shouldn't last more than three-minutes and will likely last only 30 seconds to one minute.

Individuals planning to be in the Central Materials Storage Area (where the siren is located) while the test is taking place must have with them and wear two layers of hearing protection. A sign will be posted at the CMSA gate to notify entrants of the test. The sign will be removed when the test is over.

Jefferson Lab uses the siren to notify members of the lab community to Take Cover; in the event of tornadoes and tornado warnings. It is intended to notify people who are working outdoors.

If this were an actual Tornado Warning, this message would direct you to take cover immediately in a Severe Wind take cover area.
