[On_site_list] JLab Tests New Warning Siren TODAY, 1-2pm

[deborah magaldi]

Jefferson Lab's new tornado warning siren will be tested today, Dec. 6, 
from 1-2 p.m.  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 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.

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.

More information regarding how the system will be used, and the 
appropriate actions to take will be available in the new year.

/This message is being sent on behalf of the ESH&Q Division and 
Facilities Management & Logistics./
