A South Fulton warehouse that houses oxygen and propane canisters went up in flames Tuesday morning.

Firefighters were called to Atlanta Custom Ironworks at 110 Selig Drive around 2:30 a.m. and found heavy fire coming from the center of the building, South Fulton fire Lt. Eric Jackson said. No injuries were reported.

In addition to the oxygen and propane tanks, fire crews were told the building contained propane-fueled forklifts and painting materials. Knowing that, a crew of about 40 firefighters, along with help from the Atlanta department, were called in and quickly began an aggressive attack from the outside, Jackson said.

The bulk of the flames was knocked down within an hour, he said.

By 6 a.m., the group of firefighters was down to about half, and they were hitting hot spots inside the building from above with an aerial ladder.

The cause of the fire remains under investigation.

“We will determine cause and origin, in terms of how the fire may have started, where it may have started, if anyone saw anything, what those first reports may have looked like. Any and everything that we can find out about this fire, that investigatory process is going to yield to us,” Jackson said.

That process could take several days due to the instability of the structure, he said.
