Four girls had to be rushed to hospital after chlorine leak at an Perth private girls' school

Four students attending early morning swimming training at a prestigious private school had be rushed to hospital after suffering chlorine poisoning.

St John’s WA sent four ambulances to St Mary’s Anglican Girl’s School at Karrinyup, in Perth’s south, about 7.30am on Wednesday after they were alerted to a suspected poisoning incident.

Four teenage girls were transported to Perth Children’s Hospital after being exposed to excess levels of chlorine which had leaked into the pool, while a further 16 were treated on site.

The Department of Fire and Emergency Services also responded to the Hazmat incident – sending six vehicles – and were working on site for at least an hour to fix the issue.

A spokesperson for St Mary’s said that pool equipment, which had been off because of a blackout, pumped excess chlorine into the water when switched back on. 

‘Some grounds staff and approximately 20 students attending swimming training this morning were affected,’ the spokesperson told The West.

‘Emergency services were called and, as a precaution, four students were taken to hospital for monitoring.’

The school said a ‘small amount’ of excess chlorine had been pumped into the pool after equipment switched on following a blackout (stock image) 

‘WorkSafe has completed its investigation and cleared the pool for use.’ 

The four girls were in a stable condition when they arrived at hospital and were discharged later on Wednesday.  

St Mary’s Anglican School and Worksafe have been contacted for comment.
