Coalpit Heath school evacuated after pupils fall ill
More than 20 children have been treated by paramedics after a South Gloucestershire school was evacuated in a suspected chemical incident.
Great Western Ambulance Service said it was called to The Manor C of E Primary School in Coalpit Heath at 13:15 BST.
A spokesman for the service said paramedics had found pupils suffering from headaches and nausea - and that 26 pupils had been treated on site.
Parents and children have been allowed back in to collect their belongings.
A South Gloucestershire Council spokesman said gas safety checks had been carried out and the school was expected to reopen on Tuesday.
Chemical protection suits
Avon Fire and Rescue Service said following reports six children were "drifting in and out of consciousness" it was treating the matter as a potential chemical incident.
A spokesman said two firefighters wearing chemical protection suits had gone into the building with equipment to detect hazardous substances.
"We still can't say what caused the incident but the affected children are improving and are being allowed home with letters telling them to seek medical advice if symptoms persist.
"The school will be handed back to the local authority later to allow them to carry out safety checks before it can reopen," he added.
Great Western Ambulance Service said it had sent paramedics from its hazardous area response team.
"Twenty six pupils are being treated on site and no-one has been taken to hospital," he added.
Three critical care paramedics and two doctors from the Great Western Air Ambulance charity also helped treat the casualties.
