The officer in charge of any fire department or fire company or ambulance district shall be notified promptly of the adoption of any such resolution and of any amendment or repeal thereof. In a county, city, or in a village or town, such action may be taken by local law or by ordinance instead of by resolution. As used in this section, the terms "fire department", "fire companies", "ambulance service" and "crash-fire-rescue unit" shall include all companies, squads, patrols or other units of such departments, companies or units, or volunteer ambulance services organized pursuant to section one hundred twenty-two-b of this chapter, and the term "assistance" includes the services of firefighting forces, fire police squads, ambulance services, emergency rescue and first aid squads rendered in case of a fire or other emergency, including stand-by service, to aid (1) a fire department or fire company, and (2) owners or occupants of property, and other persons, whether or not such owners, occupants or persons are receiving fire or other emergency service from another fire department or fire company or ambulance service. Except as otherwise provided by law in the case of natural disaster emergencies, a call to furnish assistance may be made by any person aware of the peril involved and the need for assistance or pursuant to any legally authorized or recognized plan for the furnishing of mutual aid in cases of fire or other emergency. The call need not originate in the municipal corporation, district or area liable for the payment of financial benefits in the event of the death or injury of a firefighter or ambulance or rescue squad member engaged in rendering such assistance. The call may be relayed through one or more persons or mediums of communication. The provisions of this subdivision shall supersede the provisions of any general, special or local law to the extent that there is a conflict between the provisions of this subdivision and such law, except that if (1) any city had, prior to April fifteenth, nineteen hundred fifty, restricted in any manner the fire department of the city from engaging in service outside the city or (2) any city, village, fire district or town has heretofore restricted in any manner a fire department or fire company or ambulance service from engaging in service or training pursuant to the provisions of this subdivision, such restrictions shall continue in effect until changed pursuant to the provisions of this subdivision.
