Local communities establish "Community emergency & resilience teams" (CERTs). These are groups of volunteers that receive basic training to intervene and aid during varied emergencies, as well as be used in routine to raise risk awareness, and assist in the reconstruction phase following a disaster. They offer help to individuals, groups, and other community members in different areas, from medicine, mental help, search & rescue, social help and more. For example, both urban and rural municipalities in Israel have arranged such teams. In large cities they operate on a community (specific geographic boundaries) level, while in rural areas they operate as a regional (more expansive) level. In an interview with an ex-security officer, he expressed his view that it can work better in rural municipalities than in big cities due to the size of the area and the sense of community. Nonetheless, several cities in Israel (for example, Acre which has a population of approximately 60,000 residents) have successfully integrated such CERT teams in their plans for emergency response. The responsibility to recruit the members of the CERT, to promote its organization and the overall management (to ensure sustainability) lies in the local municipality, most usually in the welfare departments. Following their registration as volunteers of the municipality, they are recognized as volunteers by the Nationa Insurance Institute, and thus are insured for any personal damage or injury. As part of the CERT, they are covered by the municipality's insurance, so their activities as part of the CERT is covered for professional liability.
