JLab to Conduct Monthly Test of Tornado Siren on Friday, July 5, at 10:30 a.m.
Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. Friday, July 5. 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 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 posted at the CMSA gate states this requirement.
Jefferson Lab uses the siren to notify members of the lab community, who are working outdoors, to Take Cover in the event of tornadoes and tornado warnings.
