The Office of Public Works (OPW) is to examine buildings with similar types of staircases to that which collapsed at the Natural History Museum in Dublin on Thursday, once it has established the cause of the incident.
It is understood this will concentrate on older buildings which have public access, and is with a view to examining what implications, if any, there are for other structures currently under the management of the OPW.
It is not possible to say at this stage when the museum will reopen, as a full safety audit is still ongoing.
But it is expected to remain closed for at least two weeks, although the National Museum of Ireland, which adjoins the museum building on Kildare St, will not be closed.
Ten people were taken to hospitals in Dublin after the stone staircase, built in the 1850s, collapsed at about 11.30am. Two people remained in hospital yesterday. Both were being treated for their injuries in St Vincent's hospital and were in a comfortable condition, according to a spokeswoman for the HSE.
They were part of a group of 21 teachers who were attending a science appreciation course organised by the Natural History Museum and Dublin Zoo.
Most had open-wound injuries from sharp edges of the granite staircase and were discharged yesterday evening.
According to the OPW spokesman, it has engaged an international expert to find the cause of the staircase's collapse.
Its own architects and engineers entered the building after being given the "all clear" by the Health and Safety Authority (HSA), whose inspectors visited the site following the incident on Thursday.
They are conducting a full audit of the entire building from a health and safety perspective.
This is expected to continue over the weekend, with a view to reopening the museum to the public as soon as is possible. Once this audit is completed, and the cause of the incident established, it is intended to examine similar buildings to see what implications, if any, there are.
A spokesman for the HSA said responsibility for the health and safety audit of the building rests with the OPW, but added that it was available to provide technical assistance should it be required.
