Scope

The document provides guidelines for developing, managing and implementing public warning before, during and after incidents. It is intended for any organisation with responsibility for issuing public warnings (local, regional, national or international). The standard assumes that hazard and risk assessments have already been carried out and does not replace risk assessment processes.

Key topics and requirements

• Principles for public warning: clarity, timeliness, relevance and authority.
• Roles, governance and responsibilities for issuing and approving warnings.
• Message content and structure: what to say, what actions to take, and how to present uncertainty.
• Channel selection and multi-channel dissemination to maximise reach and redundancy.
• Accessibility and inclusiveness (language, disability access, reach to vulnerable groups).
• Interoperability and coordination with broadcasters, telecoms, emergency services and partners.
• Testing, exercises, monitoring and post-event evaluation to improve warning performance.
• Record-keeping, legal/regulatory considerations and privacy/data protection for warning systems.
• Integration with broader emergency management and continuity arrangements.

Typical use and users

Used by emergency management agencies, civil protection authorities, local governments, public safety broadcasters, telecommunications operators (for cell broadcast/warning platforms), large venue and event managers, utility companies, NGOs involved in disaster response and organisations responsible for community warning and resilience planning.
