Firefighters continued to work Tuesday to douse a warehouse fire that broke out more than 24 hours earlier in northwest Atlanta.

Fire crews responding to the 4 a.m. Monday fire in two large recycling warehouses “could see it from a long ways away,” Atlanta fire Battalion Chief Kevin Roberts told the Atlanta Journal-Constitution.

“We arrived to find large amounts of fire and limited access,” Roberts said.

He said crews were working to douse the flames from the outside, using three aerial units.

“We’re not going inside because it’s a collapse hazard,” Roberts said.

One of the buildings burning in the 700 block of James P. Brawley Drive was about 175 feet by 50 feet, the other slightly smaller at 100 by 50 feet, according to Roberts.

He said firefighters were fortunate that winds have been calm.

“Of course, there’s toxins with the amount of smoke we’ve got here,” he said. “I’m sure there’s toxins in there, I just don’t know what they are. Luckily, most of [the smoke] is going up and away and we don’t have any of our crews operating in the immediate part of it.”

Firefighters will have to “get heavy equipment in here and remove some of this stuff so we can get water to it,” Roberts said. “We’ll be in here until tomorrow, no doubt.”

Fire officials told Channel 2 Action News on Monday that it could be several days before the fire is completely out.
