Häiresõnum

Häiresõnum is a formal public warning message used in Estonia to inform residents about imminent danger, ongoing emergencies, or situations requiring protective actions. It is issued by competent authorities such as the Police and Border Guard Board, the Rescue Board, local municipalities, and other state agencies. The aim is to convey essential information quickly, enabling people to take appropriate safety measures.

A typical häiresõnum includes the nature of the threat (for example severe weather, chemical or radiation hazards, traffic accidents, or security incidents), the affected area, the expected timeframe, and specific instructions (seek shelter, evacuate, avoid a location, follow official updates). The wording is standardized to minimize confusion and ensure clear guidance.

Delivery is multi-channel: loud sirens, mobile alerts (SMS, app notifications), radio and television broadcasts, official websites and social media, and public address systems in buildings and at facilities. In many cases, a national emergency alert system coordinates the dissemination, with local authorities providing updates as needed.

Operation is part of Estonia's national emergency warning system. It is coordinated by responsible authorities and activated under defined risk criteria. Messages are preceded or followed by verification, and after the danger passes, a deactivation message or update is issued.

The häiresõnum is a tool of risk communication aimed at protecting life and property by informing the public and guiding protective actions during emergencies.
