The canister apparently fell from a vehicle at the northwest corner of Winnetka Avenue and Vanowen Street, according to a Los Angeles Fire Department statement.
The Fire Department will investigate the incident according to protocol, officials said in a news alert.
Lanes or roadways will remain closed until operations are complete, officials said. Motorists should avoid the area, if possible, and can expect congestion and delays.
