A natural gas leak that had resulted in an explosion at a Chandler printing facility has been investigated for the cause of the explosion. The incident that left four people injured on August 20 was caused by a human error coupled with a prematurely degraded pipe. The accidental cause was clarified in the preliminary findings that were released on Wednesday.
The explosion was investigated by several agencies, which included the police and fire departments in Chandler. Investors from ATF’s National Response Team, along with the crews from Southwest Gas also were a part of the investigation. Altogether, the investigators found no evidence suggesting the explosion at the Platinum Ring was caused due to some foul play.
Back in 2012, the PHMSA agency had deployed an advisory with the U.S. Department of Transportation. The issued guide spoke of the Driscopipe 8000 pipe along with the potential material-related degradation hazard.
