An ammonia leak at a cold storage warehouse in downtown Los Angeles was first reported about 7:30 p.m. at 400 S. Central Ave. LA city firefighters quickly responded and cordoned off the area. This clip originally aired on the NBC4 News at 11 p.m. on Dec. 29, 2012.
An unidentified odor near downtown's Arts District is being attributed to a chemical leak.
The odor was first reported at 7:37 p.m. at 400 S. Central Ave., said Brian Humphrey of the Los Angeles Fire Department.
Initial reports were that there was an ammonia spill. Officials later clarified that there was a chemical leak coming from machinery on a roof.
An LAFD hazmat team was dispatched to the area and officials secured a valve to stem the leak, Humphrey told City News Service.
A 500-foot exclusion zone was issued in the area, meaning no one was allowed anywhere within the radius, Humphrey said.
"We cleared about a block in either direction and found out that we did actually have a leak from one of the pipe's on the roof, which was plugged," said Greg Gibson of LAFD. "
No cases of illness were confirmed, and no one was taken to a hospital, Humphrey told CNS.
Correction: An earlier version of this story erroneously reported there were evacuations in the area. An exclusion zone was issued; not an evacuation. The story has been updated.
