Four people remained hospitalized Wednesday with critical burns and other injuries sustained in an explosion involving commercial pyrotechnics in Santa Clarita.
Authorities were called at about 4:45 p.m. Tuesday to the 25100 block of Rye Canyon Loop, off Kelly Johnson Parkway, on a report of an explosion on a movie set, said Ed Pickett, supervising dispatcher with the Los Angeles County Fire Department.
The location was later determined not to be a film set, but the blast involved equipment owned by individuals who are in the movie industry, said Deputy Rick Velazquez of the Los Angeles County Sheriff’s Department’s Arson Explosives Detail.
The sheriff’s department said the explosion “was caused by the processing of commercial pyrotechnics, which were owned by a private company.”
Video footage from the area showed large shipping containers with apparent fire damage.
The four people found burned had “extensive injuries” and were taken to a trauma center, the department said. Two of them were later taken to a burn ward.
A brush fire that broke out after the explosion was held to about one acre before being knocked down by firefighters, Pickett said.
Authorities are investigating the cause of the fire.
