An explosion at an industrial park in Valencia sparked a brush fire and sent at least four people to the hospital Tuesday afternoon, officials said.
The incident was initially believed to have occurred at a movie set, but officials later described it as an industrial accident involving a private business.
Crews responded to initial reports of a possible explosion on the 25100 block of Rye Canyon Loop just before 4:45 p.m., according to the Los Angeles County Fire Department.
Firefighters arrived at the scene just before 5 p.m. and reported a quarter-acre brush fire creeping uphill, officials said.
Crews managed to stop the forward progress of the blaze, dubbed the Rye Fire due to its proximity to Rye Canyon Loop, around 5:20 p.m. after it grew to an acre, the Fire Department said in a tweet.
Fire officials reported that three people with “critical burns” were transported to a local hospital. A fourth victim drove themself to a local emergency room.
Aerial video from Sky5 showed the blaze occurred near a storage site. Officials later said the incident was an accident involving a private business within the Southern California Innovation Park, and not a movie set.
The Santa Clarita Valley Sheriff’s Station also confirmed later that no filming had been taking place when the explosion occurred.
Fire crews and a hazardous materials team were investigating the incident, the Sheriff’s Station said in a tweet.
No homes were threatened and no evacuations had been ordered.
