Text Alert Over Cisco Phones will be used with Site-Wide Alert to Remind Lab Community of Monthly Tornado Warning Siren Test at 10:30 a.m. on Friday, Feb. 7

Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, Feb. 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.

Anyone 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 is posted at the CMSA gate to remind individuals of this requirement.

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

Public Affairs sends out a notification over the Jefferson Lab Site-Wide Alert (SWA) system (email, page and Cisco phone text messages) on the morning of these tests so members of the lab community aren’t caught unaware when the siren sounds.
