McMinnville Fire Department’s free smoke detector program is still hot after almost five years.“This year, we have been to 40 homes and put up 170 smoke alarms,” said Fire Chief Kendall Mayfield. “We hope to double that this coming year.” The department entered into a partnership with the State Fire Marshal’s Office in March 2013 as part of a statewide distribution of smoke alarms in an effort to both educate and equip Tennesseans to incorporate fire safety into their daily lives.
