Tools for Chemical, Biological, Radiological and Nuclear (CBRN) Hazards

FEMA has developed a standardized suite of chemical, biological, radiological and nuclear (CBRN) response capabilities for federal, state, local, tribal and territorial emergency responders and planners to rapidly and effectively minimize loss of life, protect the environment and maintain the economy.

National Common Operating Platform for Responding to CBRN Hazards

The CBRNResponder Network is a single, secure platform for all chemical, biological, radiological and nuclear (CBRN) incident data-sharing and multi-hazard event management, integrating multiple federal assets and national-level policy guidance.

CBRNResponder includes ChemResponder for chemical incidents and RadResponder for radiological/nuclear incidents. BioResponder is in-development for biological incidents.

With RadResponder and ChemResponder, more than 1,500 organizations nationwide can view a common event space and robustly prepare for and respond to radiological or chemical threats.

CBRNResponder is sponsored by FEMA and our partners.

Key Planning Factors

Key planning documents help local and state planners identify key planning factors (KPF) that could substantially aid the recovery process by decreasing recovery timeline and costs, improving public health and safety and addressing major resource limitations and critical decisions.

Interactive Web Tools

Interactive, web-based strategic planning tools provide more realistic visualizations of hazardous material release behavior and impact estimates to help planners understand how an event may unfold, an event’s impact and possible response actions.

The Improvised Nuclear Device City Planner Resource (iCPR) and Chemical City Planner Resource (chemCPR) are currently in beta testing, available to planners via the Department of Energy's CMweb portal. A Biological CPR is in development.

Features include:

  • Animations, maps, movies and editable reports
  • Multiple scenarios for 60 U.S. cities
  • Resource planning
  • Animated fallout effects
  • Maps for evacuation and shelter planning
  • Interactive GIS display

Regional CBRN Coordinators

FEMA's Regional CBRN Coordinators operate out of each of FEMA’s 10 FEMA regional offices and serve as a point of contact for CBRN preparedness and incident response activities for all stakeholders and partners.

To identify and reach your local Regional CBRN Coordinator, contact your local FEMA Regional Office. You may also reach out to FEMA Headquarters for the Regional CBRN Coordinator Program Manager by sending an email to fema-cbrn-support@fema.dhs.gov.

Operational Specialists

You can also request the support of a Radiological Operations Support Specialist (ROSS), which are subject matter experts trained to assist emergency managers and first responders in dealing with the unique challenges presented in an IND incident or other large radiological emergencies using the Incident Command System structure. Similar support is being developed for chemical and biological incidents.

The ROSS can deploy as a single asset or strike team depending on the need by contacting fema-ross@fema.dhs.gov.

National Response Framework

The CBRN Annexes to the National Response Framework provide guidance and serve as a reference for federal agency planning efforts.

Community Lifelines

The Hazardous Materials Lifeline is part of the Community Lifelines Toolkit developed by FEMA to increase effectiveness in disaster operations and better respond to catastrophic incidents.
