There is an exam on at the school this morning which will continue as normal. A spokeswoman for the school said: "The situation is that we have an exam on at the moment and that has to be our priority."
The school buses have been booked to collect students at 11.00. The pupils are advised to make their normal journey home.
An engineer was called out to the Emmbrook Road school earlier today but was unable to fix the problem.
