US: A series of scattered fires that erupted on 11 April 2015 at Essroc Cement in Nazareth, Pennsylvania have been deemed accidental by the Vigilance Hose Co.
The initial fire began shortly after 16:00 on an underground conveyor belt that transports stone from Essroc's plant II to plant I in Nazareth, said fire chief Danny Keenhold. He said an unidentified malfunction on the belt caused the fire, which began underground. The fire then ignited a separate above-ground portion of the conveyor belt. It took firefighters from seven different agencies about two hours to extinguish the fire from both ends.
There were no reported injuries to Essroc crews or firefighters. The conveyor belt will now need to be repaired. Keenhold said that in the interim trucks will transport stone between the plants.
