The Civil Contingencies Act assigns primary responsibility for emergency planning to local emergency responders. This includes a duty to make the public aware of the risks of emergencies and how responders plan to deal with them if they occur; and to warn the public and provide them with information and advice as necessary if an emergency is likely to occur or has occurred.
To support local responders with their duties under the Civil Contingencies Act the Cabinet Office provides a range of statutory and non-statutory guidance. The core statutory guidance 'Emergency Preparedness' sets out the duty to communicate information about risk and warning and informing during an emergency and provides advice on how those duties might be carried out.
In addition the Cabinet Office provides further information and examples of good practice for communicating with the public.
