Thanks, flutters. Do you have a url for this? a text document?
Yes, the information is on FEMA’s website. It’s listed in PDF documents. The specific info I posted is under the heading “Technological & Man-Made Hazards” and sub-heading “National Security Emergencies …Terrorism; Chemical and biological weapons; Nuclear and radiological attack; Homeland security advisory system” near the bottom of the page.
Here is the link: FEMA
