JLab Tests Tornado Warning Siren on Friday at Noon

JLab Tests Tornado Warning Siren on Friday at Noon

Jefferson Lab's tornado warning siren will undergo its monthly operational test at 12-noon on Friday, April 6. 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 while the siren is being tested must have with them and wear hearing protection.

Jefferson Lab uses the siren as a mechanism for quickly notifying members of the lab community in the event of tornadoes, tornado warnings, and fast moving severe weather.

If this were a Tornado Warning, you would be directed to immediately take cover in a Severe Wind take cover area.

This message is being sent on behalf of Jefferson Lab's ESH&Q Division and Emergency Manager.
