The coordinator for emergency services and disaster agency may, in collaboration with other public agencies within his immediate vicinity, develop or cause to be developed mutual aid arrangements with other political subdivisions, and taxing districts within the state for reciprocal disaster assistance in case of disaster too great to be dealt with unassisted. The mutual aid shall not, however, be effective unless and until approved by each of the political subdivisions. The agreements shall be consistent with the state emergency operations plan and state emergency management program. In the event of such a "disaster", as described in section 4-1-3 of this chapter, it shall be the duty of each local and interjurisdictional department for emergency services and disaster operations to render assistance in accordance with the provisions of such mutual aid arrangements.
