The Belfast Trust has pleaded guilty to failing to ensure the safety of staff at Belfast City Hospital in an incident linked to asbestos, the BBC reported.
It also admitted failing to tell subcontractors about the presence of asbestos before they started work at the hospital last January, and to failing to manage the risk.
At Belfast Crown Court on Friday, a Trust representative pleaded guilty to three charges under health and safety legislation.
A fourth was not proceeded with. The Trust will be sentenced next month.
