Jacob DeLung, 20, fell through the floor of a mobile home on McIver Road in Florence County while battling a large brush fire Wednesday.
He was airlifted to the Augusta Burn Center for first, second and third degree burns to his chin, ear and neck.
DeLung is the son of Windy Hill Fire Chief John DeLung.
DeLung says his son's spirits are pretty good and he loves being a firefighter. He's hoping he will be released from the hospital in a few days.
Another firefighter from the West Florence Fire Department was treated for a broken ankle. A third firefighter was also hurt. He suffered a knee injury. That firefighter works with the City of Florence Fire Department.
They're expected to make a full recovery.
Anthony Eaddy with the South Carolina Forestry Commission says this fire started as a homeowner's debris burn that got out of control.
Eaddy says Mingo Robinson is charged with Failure To Notify Before A Burn and Allowing Fire To Spread To Another's Property. He was fined $700.
The fire burned a mobile home and several cars. At one point it was threatening a few houses.
Eaddy says the fire burned about 12 acres. It is under control and contained.
Windy Hill, Florence City, South Lynches and West Florence Fire Departments were all called to the scene, along with the South Carolina Forestry Commission.
