An investigation is under way after a visitor at an agricultural machinery show near Lisburn was injured by a storm-damaged marquee on Thursday.
The man was treated at the Lagan Valley Hospital for minor injuries but is understood to have been released soon afterwards.
Show organiser Andrew Short said the incident occurred when high winds blew a marquee apart.
“The event had to close due to adverse weather conditions. The show was evacuated as per event plan and everybody left.
“There will be an investigation in the morning with our health and safety people,” he said.
“There was one person who sustained a head injury but we had first aid on site. He went to the Lagan Valley for precautionary treatment.
“It could have been a lot worse but we implemented our event plan and everybody was evacuated within minutes,” Mr Short added.
Stormont agricultural committee chairman William Irwin MLA said he was thankful only a small number of people were in the marquee at the time, and that he hopes the man makes a swift recovery.
“I have been informed that he had only stepped away from an exhibitor’s stand and was then struck by the marquee supports which had been dislodged by the strong winds.
“An exhibitor contacted me who was in the marquee and he was very shaken by this incident as large steel supports were literally flying everywhere and people really had to move fast to get out of the way,” he said.
A spokeswoman for Lisburn City Council said: “This event is managed by a private company. Under its statutory responsibilities, Lisburn City Council’s health and safety officers will be investigating the incident.”
