FEMA recently released an updated version of its Nuclear Detonation Response Guidance, which delineates missions and tactics that should be executed by first responders, emergency managers, and other state, local, tribal and territorial response organizations following a nuclear detonation in or near their jurisdiction.

The updated report, Nuclear Detonation Response Guidance Planning for the First 72 Hours, uses the first 72-hour time frame as a notional target to help emergency planners focus their efforts on developing actionable strategies that would have the greatest impact on lifesaving efforts, which should be the primary focus during the first few days after a nuclear detonation. Specifically, the document includes guidance on pre-detonation tactics and how to protect the lives of first responders and the public; develop a common operating picture; establish a coordinated multi-jurisdictional response; and prepare for the integration of support arriving from other jurisdictions, states, and federal agencies across the country. Access the full guidance report below.

Relatedly, a recent article in Homeland Security Today highlights the threat of a nuclear electromagnetic pulse (EMP) to critical infrastructure. As described in previous WaterISAC reports, an EMP attack against the U.S. could have devastating effects on critical infrastructure, including to the water sector, with water and wastewater utilities having to contend with long duration power outages. To mitigate the effects of an EMP strike, WaterISAC previously shared guidance from DHS and the EIS Council. Read more at Homeland Security Today.
