Hall County firefighters responded Monday morning to mobile home and tractor-trailer blazes within a few hours of each other.

Firefighters responded at 2:45 a.m. to neighbors' report of a structure fire in the 3900 block of Wiley Road in North Hall.

Upon arrival, firefighters found a 20-foot by 40-foot mobile home engulfed in flames.

"The structure was a total loss," Fire Chief David Kimbrell said. "The time of day attributed to the advance of the fire because no one was up and awake, and it burned before it was discovered."

No one was home at the time of the fire, and the estimated loss is $60,000, the chief said.

Then, at 7 a.m., the fire department received calls of a truck that had pulled some power lines down on Athens Highway.

Another call followed that a tractor-trailer was on fire on Athens Highway just south of A L Mangum Road in East Hall, the chief said.

Upon arrival, firefighters found the tractor portion of the trailer was fully involved in fire. The trailer was empty. No one was injured.

"The driver was out of the truck when we arrived," Kimbrell said.

The truck had spilled some 60 gallons of diesel fuel on the ground from the tanks.

The Georgia Environmental Protection Division and a cleanup company were notified of the spill, Kimbrell said.

The causes of both fires weren't known Monday.
