Fire or police department warning procedures for shelter-in-place could include:
  • "All-Call" telephoning -- an automated system for sending recorded messages, sometimes called Reverse 911
  • Emergency Alert System (EAS) broadcasts on the radio or television
  • Outdoor warning sirens or horns
  • News media sources -- radio, television and cable
  • Weather radio alerts from the federal National Oceanic and Atmospheric Administration (NOAA)
  • Residential route alerting: Messages announced to neighborhoods from vehicles equipped with public address systems
Facilities that handle potentially dangerous materials, like nuclear power plants, are required to install sirens and other warning systems (flash warning lights) to cover a 10-mile area around the plant.
