Two people -- a firefighter and an employee -- were injured in an explosion and ensuing fire at a Carroll Township excavating company Thursday.
Firefighters from three counties were dispatched about 3:30 p.m. to R L Livingston Excavating & Paving, Inc., 1 Blair Mountain Road, along Old York Road.
The unnamed employee suffered a head injury in an explosion in the company's workshop and was a taken to Hershey Medical Center, said Sean Kapfhammer, Carroll Township Police chief.
His condition was not known Thursday night, said Bill Turner, spokesman of the township's emergency manager agency.
A Franklintown firefighter was injured when part of the workshop's roof collapsed on him.
"He was not seriously injured but was taken to Holly Spirit (Hospital)," Turner said.
The firefighter was wearing a helmet.
Explosions: Dave and Kathy Zimmerman said they were in the yard of their Blair Hollow Road home when they heard loud noises coming from the nearby business.
"We heard loud booms," Kathy Zimmerman said. "There were a lot of booms."
Dave Zimmerman said the four or five booms the couple heard sounded like the tailgate of a dump truck slamming against the bed of the truck.
"I didn't know what it was," he said.
But when the couple looked in the direction of R L Livingston, they saw flames shooting from a building, they said.
Kapfhammer confirmed there were several explosions at the workshop.
"There were numerous explosions from what I understand," he said.
Fire: There were a number of tanks that contained an unknown chemical in the workshop, used as a repair area where employees fix equipment the business uses, at the time of the explosion, Kapfhammer said
The York County Hazardous Materials Team was dispatched to the scene because of the presence of the tanks.
Firefighters from York, Adams and Cumberland Counties were dispatched to the blaze, and crews rolled up on the scene to find the building engulfed in flames.
"Firefighters arrived and found the place pretty much fully engulfed," Kapfhammer said.
Closed: A section of Old York Road in the area of the blaze was closed for a number of hours as firefighters worked the scene.
Because the fire happened in a rural area without fire hydrants, tankers had to shuttle in water from a nearby pond.
Firefighters fought to douse the flames from above with the aid of the raised ladder on a ladder truck while other firefighters worked to extinguish the blaze at ground level.
The blaze was extinguished just after 6:30 p.m.
Officials said Thursday that it's not clear what caused the explosions. A fire marshal is investigating the incident.
