Overview

prEN ISO 22322 / ISO 22322:2022 - Security and resilience: Guidelines for public warning provides guidance for developing, managing and implementing public warning systems before, during and after incidents. Published as the second edition (2022), the standard applies to any organization responsible for public warning at local, national or international levels. It focuses on structured public warning processes (alert and notification) to protect people, reduce harm and support incident response. Note: the standard does not cover the risk assessment process used to identify hazards.

Key topics and technical requirements

• Public warning system: establish, document, implement, maintain and continually improve a public warning system based on a public warning policy.
• Two core functions:
  • Hazard monitoring - ongoing monitoring, early detection, scientific/credible evidence, defining emergency measures, and notifying dissemination teams.
  • Warning dissemination - converting monitoring outputs into alerts/notifications, specifying message content and channels, and promptly disseminating warnings.
• Framework design and roles: assign responsibility for authorizing public warning (trained individual/group) and clarify inter-organizational coordination between monitoring and dissemination functions.
• Operational process elements: identify people/areas at risk, capture area characteristics, specify information content and safety actions, select appropriate warning methods, and consider human factors and vulnerable groups.
• Documentation and evaluation: log operational activities in a retrievable format and evaluate performance regularly - evaluation intervals should not exceed five years. Use findings to drive continual improvement.
• Public awareness and community engagement: maintain ongoing public awareness programs and consult community representatives, NGOs and other stakeholders.

Practical applications and users

Who should use it:

• Emergency management agencies, civil protection authorities and public safety organizations
• Municipalities and regional governments implementing public alerting systems
• Telecommunications and broadcast services providing warning channels
• Private-sector operators managing campuses, industrial sites, transport hubs and critical infrastructure
• NGOs and international relief organizations coordinating cross-border warnings

Practical uses:

• Designing or upgrading an integrated public warning system (alert and notification)
• Defining roles, authorization and communication procedures for rapid emergency messaging
• Selecting and testing multi-channel dissemination (sirens, mobile alerts, broadcast, social media)
• Developing public awareness campaigns and training responders
• Establishing evaluation, audit and improvement cycles to enhance resilience

Related standards

• ISO 22300 - Security and resilience: Vocabulary (normative reference)

Keywords: public warning, emergency management, warning dissemination, hazard monitoring, public alert, emergency communication, ISO 22322:2022, resilience, security.

bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

ISO 22322:2022(E)
Introduction
Disasters, terrorist attacks and other major incidents need an effective incident response in order to
save lives, mitigate harm and damage. Emergency response organizations need to respond quickly to a
developing emergency situation. Time to communicate is limited and often a specific message involving
practical action is to be disseminated to a large group. Simple procedures that send the message
efficiently and create the desired response can save lives, protect health and prevent major disruptions.
The protection of people at risk from harm is an important part of an incident response. Public warning
enables response organizations to alert their responders and allows people at risk to take safety
measures to reduce the impact of incidents. Effective public warning consisting of alert and notification
can prevent panic reactions and support response organizations in optimizing their responses and
mitigating the impact.
Effective incident response needs a structured and pre-planned public warning. Public warning is
based on two functions: hazard monitoring and warning dissemination. It is also necessary to establish
a mechanism for risk identification, hazard monitoring, decision-making and warning dissemination,
and to evaluate and improve.
