Funds paid to eligible volunteer fire departments shall only be expended for fire protection purposes, including training, supplies, and equipment. The funds may also be expended to purchase liability insurance to insure coverage of acts or omission which are directly related to the functions of a volunteer fire department which are committed by a volunteer fire department or the personnel of a volunteer fire department, or both. The funds may not be expended for salaries, food, drink, social activities, or fundraising activities. After receiving funds, the volunteer fire departments shall keep accurate records to verify that the funds were properly expended. By September 15th of each year, the department shall file a form with the county commission detailing the expenditure of all funds during the previous 12 months. The filing shall also account for all unspent funds and whether the unspent funds have been obligated. The county commission shall supply the accounting forms to each eligible volunteer fire department.
