Firefighters from multiple companies responded to a fire alarm at a plant in Valmont Industrial Park in West Hazleton on Sunday afternoon. Firefighters and the plant’s sprinkler system extinguished the fire, which spread to the roof, Cara said. Crews could be found walking on the building’s roof after accessing it from a ladder truck.

Smoke rolled off the roof at Greif Brothers, 95 Jaycee Drive, and was visible for a time from Route 93 after firefighters were dispatched there around 4:30 p.m. The smoke began to dissipate and finally disappeared from outside view by about 5 p.m.

Deputy Fire Chief Brian Cara said crews spotted the smoke upon arrival after being dispatched to the facility by Luzerne County 911 for an activated fire alarm and found a fire in a hopper holding polystyrene.

Cara said firefighters ventilated the building and found the fire didn’t extend elsewhere. Damages amounted to mostly smoke and water, Cara said. He expected the damage would “cause little change” in Greif Brothers operations.

No injuries were reported. Employees were at work when the fire broke out and evacuated, he said.

Cara said multiple fire companies were called to respond as a precaution. With commercial buildings, Cara said, it’s difficult to predict how quickly and where the fire will spread.

Firefighters from Hazleton, Valley Regional, Freeland, McAdoo, Hazle Township and Mahanoy City responded, as did utility companies PPL and UGI. American Patient Transport Systems Inc. also responded, as did fire police to direct traffic.
