Fire reported in chlorine building at Moccasin Bend one day after leak

Chattanooga Fire Department responders prepare to use a remote ladder pumper to hose down the chlorine building as smoke pours from the top at the Moccasing Bend Wastewater Treatment facility Monday, Mar. 16, 2015, in Chattanooga, Tenn.

Emergency personnel have returned for a third time to Moccasin Bend and workers were evacuated from part of the waste treatment plant, where a chlorine leak on Sunday was

just in time.

Seven emergency vehicles were seen at the Moccasin Bend Wastewater Treatment Plant Monday afternoon surrounding one of the buildings, and yellow caution tape was stretched across the road. Smoke poured from one of the buildings as firefighters sprayed it down, causing a mushroom cloud of steam to escape.

A reporter and a photojournalist both smelled an odor they likened to a swimming pool filled with chlorine, but the fire department said that their testing tools revealed no leaking chlorine gas.

The Chattanooga Fire Department said a so-called scrubber, which is used to remove dangerous chemicals from the air before they escape into the atmosphere, is on fire and is causing the smell. The scrubber has been overheating since 4 a.m.
