Jefferson Lab's tornado warning siren will undergo its monthly
operational test at 12-noon today (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.<br>
<br>
Don't respond to the siren; this is a test of the siren system and
not a personnel response exercise.<br>
<br>
The test shouldn't last more than three-minutes and will likely last
only 30 seconds to one minute.<br>
<br>
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 Central Materials Storage Area gate to notify
entrants of the test. It will be removed when the test is over.<br>
<br>
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.<br>
<br>
More information about the siren is in the March 2012 On Target
newsletter, currently posted at: <br>

If this were an actual Tornado Warning, this message would be
directing you to take cover immediately in a Severe Wind take cover
area.<br>
