Six workers were taken to hospital today following a mercury spillage at Belfast City Airport.
They have since been given the all-clear and were released from hospital.
They were each getting what the airport called a "precautionary check-up" after baggage handlers unloading cargo on a Flybe flight from Birmingham discovered a small mercury spill in the cargo hold.
The aircraft was cordoned off while the spillage was dealt with. Belfast City Airport insisted that none of the passengers had been in any danger.
"At no time were any of the 83 passengers and five crew in any danger and they left the airport as normal with the baggage because luggage and cargo are kept in separate compartments in the Bae 146 aircraft involved," said a spokesman.
Two cargo handlers and three baggage handlers were taken to Belfast's Royal Victoria Hospital for check-ups and a firefighter went to the Ulster Hospital in Dundonald.
The airport continued to operate as normal but the aircraft would remain quarantined until it had been cleaned and passed fit to fly, said the spokesman.
