One of the affected country's main responsibilities is to ensure that its LEMA is functional during the disaster so as to exercise its primary role in initiating, coordinating and organising the international humanitarian assistance on their territories, and that they have overall responsibility for the command, coordination and management of the response operation. This includes having RDCs prepared and operational, locations for Bases of Operations and/or OSOCC/UCC planned.

受灾国的一个主要责任是确保 LEMA 在灾难发生期间发挥其职能：在本国行使其发起、协调及组织国际人道主义援助行动的职能。也就是说，LEMA 全面负责控制、协调及管理响应行动，包括准备和运行 RDC，确定行动基地的位置和/或制定 OSOCC/UCC 计划。
