A gas leak caused by a long peg used to erect a marquee caused the Buchan school to be evacuated this morning (Thursday).
Engineers are currently on site working to fix the problem. No one was placed at risk and full supplies have been maintained at all times.
Pupils at the Castletown school were evacuated at around 10.15am, and as their day was due to finish at 12.30pm anyway, will not be returning.
The incident arose as contractors set about dismantling the marquee in the school grounds.
When the marquee was put up earlier this week, it appears the peg was placed through the medium pressure main. As the peg was removed this morning, the gas began to escape and the problem came to light.
Manx Gas customer services director Robert Gardiner said: ‘We have stemmed the flow of gas and we are now carrying out pipe repairs, which will be completed today.’
