Firefighters battled flames for nearly an hour Wednesday at an intense midday fire at a Peachtree Corners apartment complex that displaced 37 people.

Despite the fire’s intensity, no one was injured and only one dog had to be rescued from the blaze, Gwinnett fire spokesman Lt. Andy Lane said. The dog was quickly reunited with its owner and the Red Cross is working with the complex’s leasing office to relocate the displaced residents while their apartments are repaired.

Firefighters were called to the Fields at Peachtree Corners just before 11:40 a.m., Lane said. Plumbers working at the property noticed the fire and called the leasing office, and someone there called 911.

When crews arrived, they found flames and smoke coming from the center units of a connected row of townhouse-style apartments, Lane said. Firefighters attacked the flames with hand lines and used a ladder truck to spray from above.

It was nearly 12:40 p.m. before the fire was extinguished, Lane said, but the damage was minimized by firewalls in between the units. The fire was started by accident as the result of work being done by the plumbers who initially reported it, according to Lane.
