Overview
ISO 22322:2022 - Security and resilience - Emergency management - Guidelines for public warning - provides guidance for developing, managing and implementing public warning before, during and after incidents. Applicable to any organization responsible for public warning (local to international), the standard defines a structured public warning system built around two core functions: hazard monitoring and warning dissemination. (Note: prior risk assessment of hazards is outside the scope of this standard.)
Key topics and requirements
- Public warning system requirements: establish, document, implement, maintain and continually improve a public warning system based on a public warning policy. System elements must be planned, resourced, communicated and regularly trained.
- Two-function framework:
- Hazard monitoring function - identify hazards, set monitoring indicators, collect scientific or credible evidence, provide early information and notify the warning dissemination function.
- Warning dissemination function - convert evidence into alerts and notifications, specify dissemination procedures, consider diverse information needs (including vulnerable groups), and promptly distribute warnings.
- Authorization and decision-making: designate trained individuals or groups responsible for authorizing public warning based on inputs from monitoring and dissemination functions and the public warning policy.
- Public warning process: procedures for identifying hazards, defining criteria for notifications/alerts/all-clear, capturing affected areas, specifying message content, selecting methods and disseminating warnings.
- Human factors & public awareness: address communication needs of diverse and vulnerable populations; maintain continuous public awareness (see Annex B).
- Evaluation and improvement: evaluate performance of monitoring and dissemination regularly (intervals not exceeding five years) and whenever expected public safety actions do not occur. Maintain retrievable operational logs.
- Informative annexes: relationship between alert and notification (Annex A) and public awareness guidance (Annex B).
