The coordination arrangements for major emergencies are established under the Framework for Major Emergency Management and the associated guidance documents, involving local authorities, An Garda Síochána and the HSE. These arrangements apply equally to offshore island communities.
In the event of a significant emergency, the Principal Response Agencies undertake an assessment of the situation and determine the most appropriate protective actions for those affected. Decisions regarding evacuation are made on a case-by-case basis, taking account of the nature and scale of the incident, prevailing weather and sea conditions, transport availability, the vulnerability of those affected and the safety of both the public and emergency responders.
The preferred protective measure in most emergency scenarios, including severe weather events, is usually to advise people to remain safely sheltered in place.
Evacuation is considered by the Principal Response Agencies where an assessment by the relevant authorities determines that it is necessary and represents the safest course of action in the circumstances.
Where evacuation is required, the Guidance on Evacuation and Rest Centres provides a framework for the coordinated movement of affected persons and the provision of humanitarian assistance, including temporary accommodation and welfare supports.

Local authorities have primary responsibility for these humanitarian aspects of the response, while An Garda Síochána coordinate evacuation operations.
Any decision to undertake a partial or full evacuation operation is based on the prevailing circumstances assessed by the Principal Response Agencies, taking account of public safety as the key consideration.
