Six people hospitalised after pool chemical mix-up in Sydney CBD

September 26, 2018

On September 19, a hotel worker incorrectly mixed chemicals at the swimming pool of the Pullman Hotel in Sydney’s CBD, resulting in dangerous gas entering the hotel’s ventilation system, affecting guests and staff.

As many as 10 ambulances arrived at the hotel just after 9am.

Steve Vaughan, NSW Ambulance acting superintendent said that just after 9am there were reports of people being exposed to chemicals, which turned out to be a total of 30 patients. They transported six patients to hospital who after treatment were all deemed to be in a very stable condition.

The person who mixed the chemicals was among those transported to hospital.

When firefighters arrived at the scene they found the smell on the 22nd floor of the hotel, and they determined a hotel worker had inadvertently mixed hydrochloric acid and chlorine.

Firefighters had finished ventilating the hotel by 11am.

SPASA advocates use of trained professionals

Peter Holland, SPASA Australia RTO manager says that the issues that caused the chemical incident in Sydney are far too frequent due to lack of knowledge regarding pool maintenance and chemical treatment of water.

He says the maintenance required by hotels, motels and public pools are a complex logistical undertaking that requires careful planning and challenging work by the maintenance team.

“SPASA recommends that only trained employees be responsible for pool and spa maintenance. Chemical handling is one of the many aspects covered in industry-run certified courses and trade qualifications.

“As a public facility, public pools must ensure that the pool and spa is under the control and management of a dedicated team member. Staff should be exposed to training in plant operation, water treatment, water chemistry and the general procedures required to maintain good water quality.”
