SIPTU members in the Dublin Fire Brigade have called for a full risk assessment of properties built or extended during the Celtic Tiger years.
This would include properties from approximately 2000 to 2014.
The trade union says the call is due to the "large number of fire safety issues", discovered in a recent survey of apartment blocks constructed during this period.
SIPTU sector organiser Brendan O'Brien said: "One of the largest property management companies in the state, Keenan Property Management (KPM), has said that significant fire safety issues have been discovered in 'almost all' of the 60 apartment developments included in a recent survey of apartment blocks it manages."
"This is stark, but unfortunately, not an unexpected finding.
"The company must be commended on the pro-active approach which it undertook in the wake of the Grenfell Tower tragedy in 2017.
"Local authorities need to show the same degree of concern and undertake a similar survey of all commercial, leisure, nursing and hospital buildings constructed or extended during the period when so-called 'light-touch regulation' was at its most extreme."
