Baltimore County will participate in the first-ever nationwide test of the Emergency Alert System on Wednesday, Nov. 9, at 2 p.m.
The test will involve virtually all broadcast radio and television stations, cable television, satellite radio and television services and wire line providers across all states and territories.
County officials say the test will resemble the local EAS tests familiar to most people, but there will be some differences in what viewers see and hear.
The message indicating, "This is a test," may last up to three-and-a-half minutes.
The purpose of the test is to assess readiness and effectiveness of the system and identify improvements that could help responders.
Though frequently used by state and local governments to send weather alerts and other emergencies, the system has never been activated nationally.
According to the county Office of Homeland Security and Emergency Management, it is important as a general rule for individuals, families and businesses to make an emergency plan and assemble a preparedness kit, as well as plan in advance how they will contact one another in the event of an emergency.
The basic emergency supply kit includes water (one gallon of water per person per day for at least three days); a three-day supply of non-perishable food; a can opener; battery-powered or hand crank radio; flashlight and extra batteries; first aid kit; a whistle; dust mask; moist towelettes, garbage bags and plastic ties; wrench or pliers to turn off utilities; and a cell phone with charger.
