A fire broke out Friday morning at a business in Franklin County.

Chambersburg Fire Department was dispatched at 9:58 a.m. to Keystone Sheets, 1465 Nitterhouse Drive, Chambersburg, according to a news release from the fire department. Staff reported that the dust collection system was on fire.

Firefighters arriving at the scene did not see anything on the building’s exterior, but inside they encountered flames in three pieces of machinery and the connected dust collection system.

The building’s sprinkler system prevented the fire from extending to the rest of the duct system and the building, the fire department said.

The fire was under control as of 10:35 a.m. Crews remained on the scene for about two hours to extinguish hot spots. The scene was cleared at 1 p.m.

The building remained under normal operation during the fire, however, the business temporarily shut down for clean-up and repairs to be completed.

Companies from throughout the county responded to the scene, including Franklin, Fayetteville, Marion, Letterkenny, New Franklin, Pleasant Hall and West End fire and EMS departments, and WellSpan Health EMS and the Franklin County Coroner’s Office rehab unit.

A voicemail message left at Keystone Sheets Monday was not immediately returned.

Keystone Sheets manufactures corrugated sheets, or cardboard used to make boxes and other packaging.
