An explosion at a print shop at a Chandler strip mall near Ray Road and Rural caused the roof to collapse, injuring at least four people on Thursday morning.
The Chandler Fire Department responded to the fire after the explosion at Platinum Printing near the 4900 block of West Ray Road.
Fire officials said the cause of the explosion is still unknown but there was a gas leak after the explosion, causing a need for evacuations.
Chandler Fire Department battalion chief Keith Welch shared that the victims were transported to the hospital with burn injuries and are in serious to critical condition.
Dr. Kevin Foster, director of the Arizona Burn Center at Valleywise Health, said the four victims sustained “propane flash burns” and may have to be hospitalized for a few days to treat second-degree burns.
The four victims suffered burn injuries to as much as 30% of their bodies.
Chandler police tweeted around noon on Thursday that there was no danger to the public
