A malfunctioning HVAC unit led to a fire scare at Northwest Guilford High School on Tuesday morning.
A few classes were briefly interrupted at Northwest Guilford High School on Tuesday morning after smoke was noticed in a portion of the school.
At around 10:45 a.m., smoke was observed in one section of the school, forcing a partial evacuation. About one quarter of classes were interrupted for one hour, while students in other parts of the campus continued on with classes as normal.
The cause of the smoke was from a small fire in an external HVAC unit due to a malfunction. The damage was confined to the unit. After an investigation, the Oak Ridge Fire Department ventilated the residual smoke and smell and students were returned to class.
