In case any county or municipally-owned equipment is damaged or lost, or in the event that any expense is incurred in connection therewith in answering a call for assistance made by another county or municipality, by reason of an emergency in another county or municipality, such loss, damage or expense, together with the cost of any material or supplies used in connection with meeting such emergency, shall be a charge against and shall be paid by such other county or municipality which issued the call for assistance. No claim for any such loss, damage, or expense shall be allowed unless, within 60 days after the loss, damage or expense is sustained or incurred, an itemized notice of such claim, authenticated under oath, is served, personally, or by registered mail return receipt requested, by the duly authorized representative of the police department concerned, upon the principal executive officer of the county or municipality to which such assistance was rendered.
