Seven people received hospital treatment after an incident at a chemical plant in Co Clare tonight.

None of the people taken to hospital was seriously injured.

The incident occurred at the Chemifloc plant at the Smithstown Industrial Estate at Shannon at around 4.45pm.

Both the fire services and the company have confirmed that a chemical reaction causing a gas emission occurred, when a batch of bleach was being loaded at the plant.

Eight units of the fire brigade from Shannon and Ennis dealt with the incident at the plant.

Seven workers, five men and two women were brought to the Mid Western Regional hospital in Limerick where some were treated for breathing difficulties. They had to be decontaminated or washed down by fire personnel outside the hospital before they could be admitted and treated at the emergency department.

The company said the workers were taken to hospital as a precaution, but that none had been seriously injured.

Clare County Fire Service confirmed that the incident at the plant had been contained at around 9pm and that it did not pose a public health risk.
