Citizen Corps is FEMA's grassroots strategy to build a nationwide culture of emergency and disaster preparedness to support national and community resilience. Citizen Corps Councils bring together government and community leaders to engage individual members of the public and organizations from all sectors to collaborate on preparedness planning, emergency response, and disaster mitigation and recovery. Engaging the public is a critical part of Citizen Corps' mission. Well-trained volunteers supplement governmental resources in all phases of emergency management. Identifying and supporting policy and practice that promote and strengthen public participation is, therefore, an important element of Citizen Corps' implementation. FEMA has learned from Citizen Corps Councils, volunteer program managers, and volunteers that liability is a significant concern and a potential barrier to volunteer involvement in emergency services. Liability-legal responsibility for one's acts or omissions-includes diverse concerns: legally imposed payment of damages for personal injury or property damage; penalties for practicing a profession or trade without the required license or permit; compensation for lost income and medical expenses of an injured volunteer; and damages for breach of contract. To offer guidance in this area, FEMA funded the nonprofit Public Entity Risk Institute (PERI) to develop the Citizen Corps Volunteer Liability Guide (CCVLG) to provide an overview of liability and to suggest some approaches to addressing these concerns.
