Riverhead firefighters found paper records burning in a second-floor records storage room at the county center when they responded to an automatic alarm this afternoon just before 1 o’clock.
There was a heavy smoke condition on the second floor when the first fire chief arrived. He immediately called for the department to respond to a working structure fire.
The fire activated the sprinkler system in that area of the building.
The chief called for the county fire marshal to respond and investigate.
Firefighters quickly put the fire out. No one was injured in the incident.
