Emergency sirens will be activated for a training exercise on the U.S. Department of Energy's Hanford Site tomorrow.

The sirens will be activated between 8:15 a.m. and 9:15 a.m. in the area of Hanford known as the 300 Area, which is near the Columbia River just north of Richland.  People near this area may hear the sirens sound, but no response is required.

Public address announcements stating "this is a drill message" will be made prior to and following the siren tone.  In the event of a real emergency, county officials would activate the Emergency Alert System to broadcast information to the public via local radio and television stations.  Sirens located along the Columbia River would also be activated if it were necessary to warn people on the river.

Periodic emergency drills and siren tests are conducted at Hanford facilities to test emergency equipment and train workers on emergency response procedures.
