Three employees have been injured in a workplace incident at Alcoa this afternoon.
Emergency services, including a rescue helicopter and five ambulances, rushed to the Pinjarra Refinery after reports of several injured about 5:20pm.
An Alcoa spokesperson said three employees were treated for chemical burns.
“A valve failure at Alcoa’s Pinjarra Alumina Refinery resulted in three employees being exposed to process material,” the spokesperson said.
“The employees were treated for burns at the refinery.
“An investigation into the cause of the incident is underway and the Department of Mines, Industry Regulation and Safety has been notified.”
It’s understood the three were exposure to caustic.
Two have since been airlifted to Fiona Stanley Hospital for further treatment.
