A fleet of ambulances ferried casualties from St Andrews to Ninewells Hospital in Dundee following Tuesday’s chemical leak in St Andrews.
NHS Tayside said the 19 casualties, who began arriving shortly after 2.45pm, were quickly assessed before being treated and discharged directly from the emergency department.
A&E consultant Brodie Paterson, who coordinated the treatment of casualties, said: “The Ninewells emergency department received 19 casualties in total, 18 of whom were walking wounded.
“We were able to treat all of today’s casualties in the department and arrangements are now being made for everyone to be transferred back to their homes.”
Thirteen fire appliances attended the incident, including three breathing apparatus teams in gas-tight suits who isolated the power in the plant room and searched the building.
The chemical, now known to be sodium hypochlorite, had leaked from a storage tank on to grass outside.
A spokeswoman for the Health and Safety Executive confirmed it was carrying out initial inquiries following the incident and was “working with the relevant authorities”.
A spokesman for the Scottish Environment Protection Agency said it had also been made aware of the incident.
A Fife Sports and Leisure Trust spokesman said: “All customers and staff were able to evacuate the building safely without assistance.
“However, 19 people, including two members of staff, were referred for medical assistance for minor breathing irritation.
“The exact cause of the incident is still being investigated by the emergency services and there is no threat to the surrounding area.
“We will continue to work with emergency services and will keep customers updated as to the status of the centre via our website.”
