Jefferson Lab is installing a severe weather warning siren, and will
test the system for the first time on Tuesday afternoon, Dec. 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>
If feasible an additional message will go out with the anticipated
time frame for the test. Don't respond to the siren; it is a test of
the siren system and not an exercise or a test of personnel
response.<br>
<br>
The test will be carried out over a period that could last from 30
minutes to an hour and will include a full three-minute test of each
tone produced by the siren: a wavering tone (also called
high-low-high or 10-4-10) and a steady blast. Additional tests of
each tone – lasting between 15 and 30 seconds each – will also take
place.<br>
<br>
Jefferson Lab plans to use 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 or other events
that require an immediate response.<br>
<br>
More information regarding how the system will be used, and the
appropriate actions to take will be forthcoming.<br>
