The blast occurred around 9:30 p.m., followed by a fireball and a loud explosion that startled residents.

The skies cleared considerably after the initial fireball subsided.

About 30 minutes after the incident, officials issued a statement confirming there was no threat to public safety and no reported casualties. Los Angeles County Supervisor Holly Mitchell told NDTV that firefighter crews were able to contain the fire quickly. She added that officials were monitoring air quality in the area and advised residents to remain indoors as a precaution, according to the Los Angeles Times.
