Crews battled a fire at a manufacturing facility last night in Adams Township.
A call came in around 8 p.m. for an automatic fire alarm in the 100 block of Fey Lane.
When crews got on scene, they found a thick gray smoke coming from inside the building. It was soon elevated to a first alarm fire, and more crews were called in to assist.
The local HAZMAT team was also called after firefighters found a number of drums in the building.
Crews were able to get the fire under control.
Officials with the Harmony Fire District say a drum of epoxy reacted poorly with another agent in the mixture, causing it to spontaneously combust.
The fire was contained to just the impacted drum.
