Students, teachers in hospital after chemical leak
Eleven high school students and two teachers have been taken to several hospitals in western Sydney after reacting to a chemical in a science laboratory.
The fire brigade says a sulphur-based substance leaked in a classroom at Moorebank High.
Part of the school was evacuated while the brigade's hazardous materials unit dealt with the chemical.
The ambulance service says about 20 people suffering nausea and eye and nose irritations were assessed, with the 13 taken to hospital as precaution.
