Stations 66, 34, 77, E86, and L52 were dispatched at 16:18 for a smoke in a classroom.

BC66-1 arrived and confirmed smoke on the third floor of the science wing with a sprinkler activation. BC66-1 also requested a RIT team and established High School Command.

E66 arrived and advanced a hose line to the entrance of the science wing. Units confirmed the fire was already extinguished and held off on advancing the line into the building. SD34 laid in from the hydrant while L77 and other units completed positive pressure ventilation to remove smoke from the third floor.

Crews remained on scene for a short period of time to secure the activated sprinkler and continue ventilation. The fire is under investigation by the township, county, and state fire marshal's offices.
