First Nationwide Emergency Alert System Test Set For Today

LOS ANGELES (CBS) — Don't panic -- it's only a test! The first nationwide test of the Emergency Alert System (EAS) will be held at 11 a.m. Wednesday, with emergency tones being broadcast on radio and cable and satellite television systems.

The EAS test will last approximately 30 seconds.

The U.S. Department of Homeland Security Federal Emergency Management Agency (FEMA) and the Federal Communications Commission (FCC) are conducting the test to determine the reliability of the Emergency Alert System.

Safety officials said the test should be a reminder that everyone needs an emergency plan for themselves and their families, as well as workplace and in-transit plans.

The EAS is the nation's first line of information for citizens during times of crisis. It is designed to enable the president to address the nation in the event of an emergency.
