Two common questions among citizens are, “How will I know there is an emergency around my home?” and “How will I get information of what to do?”
Having and knowing about “warning systems” answers these questions. A warning system consists of two parts - a signal and a message. We will look at these two parts as they currently relate to Chester County.
Emergency Alert System (EAS) (formerly: Emergency Broadcast System)
EAS exists to furnish instructions to the public in the event of a national, regional, or local crisis. Radio and television stations that are designated as EBS stations transmit alert tones and emergency information to the general public. A person would need to be listening or watching an EBS station to know that an alert has occurred. There are EBS radio monitors that may be purchased which allow the radio to remain muted until the tone is received.
NOAA Weather Radio
This type of tone-alert radio is configured to monitor one of the National Oceanic and Atmospheric Administration's (NOAA) continuous broadcast radio station. It may be used to listen to the local weather broadcast station, which is part of the NOAA system, or it can be set to activate only when the station transmits a special weather alert tone. Some NOAA weather radios can be purchased to activate when there is a county or area specific tone transmitted or a regional tone is transmitted. The system is primarily used for weather hazard communications. The NOAA weather radio can be purchased from most retailers that handle electronic products. Ensure that it is properly listed by an approved testing agency, such as UL, and that the device will receive in your area.
Residential Route Alerting
Motor vehicles equipped with public address (PA) systems travel predestined routes to notify people of the emergency, The message may give instructions or advise to tune to an EBS station for the message.
Door-to-Door Alerting
Emergency personnel go to each home, alerting residents of the emergency and giving instructions.
Vehicle Sirens
Motor vehicles equipped with sirens travel predestined routes. Similar to route alerting, the citizens will need to tune to an EBS station for the message.
Hearing Impaired
A modified weather alert radio for the deaf can be purchased that activates a pillow vibrator at the onset of a weather warning. The system can alert the deaf during night hours to disasters. In addition, Tone Deaf Devices (TDD) can be purchased and coded for weather information. People with hearing difficulties should contact their local telephone company and electronic stores specializing in communications equipment to discuss their specific needs. Please note that special equipment is also available for smoke detection in the home.
