A hazardous materials team responded Monday morning to a report of an ammonia leak at a Long Beach storage facility, prompting the closure of nearby streets and freeway ramps during the investigation.
A small leak was discovered at Long Beach Cold Storage and Logistics near Magnolia Avenue and Anaheim Street (map).
The odor of ammonia was reported at about 3 a.m. Fire officials told NBC4 a leak occurred at the same building in February.
"If there is a significant concentration, it could be deadly," said Matt Dobberpuhl, of the Long Beach Fire Department.
The Anaheim Street exit ramps were closed on both sides of the 710 Freeway early Monday. Nearby streets also were closed for about five hours.
Nearby residents were advised to stay in their homes as a precaution.
