Multiple callers reported hearing the explosion in the 13500 block of Orden Drive about 6:30 a.m., Santa Fe Springs Department of Fire and Rescue Division Chief Brent Hayward said.

First responders found the burning tanker and two injured people who had been thrown off of a truck trailer during the explosion, Hayward said.

The workers, who were contracted to work on the roof of a nearby building, were heating the asphalt when something apparently malfunctioned during the heating process, Hayward said.

“They had either a vapor explosion or a product explosion,” Hayward said.

Both workers were treated at the scene and then transported to a local hospital.

“The more critical of the two was then transferred to UCI,” Hayward said.

The second worker was also taken to UC Irvine Medical Center’s burn center a short time later, Hayward said.

Callers reporting the explosion to authorities initially described it as a propane explosion.

The cause of the explosion was under investigation, Hayward said.
