[On_site_list] JLab to Test Tornado Warning Siren on Friday at 10:30 a.m.

[deborah magaldi]

Jefferson Lab's tornado warning siren will undergo an operational test 
at 10:30 a.m. Friday, May 10.

Depending on weather conditions at the time of the test, the siren may 
be heard by anyone 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.

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 outdoors to Take Cover in the event of tornadoes and tornado warnings.

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


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