Mount Sentinel secondary school has re-opened after being evacuated Friday.
This as a result of a fan fire in their rooftop h-vac system.
The school has returned to a regular schedule.
But there may be interruptions with the heating and cooling system throughout the week.
Students are advised to wear longer sleeves or sweaters.
This is the second time in the last few months the school has been evacuated.
It happened in June after the school received threats and a student was arrested.
