This high-volume email list is for those interested in the domestic preparedness of the United States. Technological hazards include terrorism, nuclear power plant emergency, hazardous materials, and house and building fire.

After the establishment of a new Department of Homeland Security, America will focus even more on security and defense within its borders.

Links, Files, and Photos sections are available for members to locate and post more information.

Everyone is invited to support the list by joining and posting their discoveries and questions on any issue relating to domestic security, preparedness, and response.
