Companies were dispatched to a reported automatic fire alarm at the Big Boulder Ski Lodge Monday evening. While en-route, the property manager advised the county that everything was OK. Ladder 17's crew used the TIC to confirm his assessment. The exhaust fan in the restroom of the locker room area caught on fire. The property manager was in the building at the time and was able to knock it down with a dry powder extinguisher. No extension of the fire was found.
