Green Party Councillor Ciaran Cuffe has asked for more information about the type of aluminium cladding which covers most of the Poolbeg Incinerator.
It's not known whether its a similar type to the materials which have failed fire safety tests in the wake of the Grenfell Tower disaster in London.
Assistant City Chief Dick Brady says the council managers have already asked for that information.
"It is obviously a question we have asked, ourselves, and the detail has been requested. We are awaiting a reply."
Separately, it's emerged three other serious incidents have taken place at the Poolbeg Incinerator.
They happened in the first week of testing and before the lime leak at the Incinerator four weeks ago.
The separate issues relate to temperatures and the filter used to control pollution and were recorded on the 1st and 5th of June, as well as just hours before the lime leak on the 7th.
Dublin Waste to Energy which jointly operates the plant reported the incidents to the Environmental Protection Agency.
The details emerged at a meeting of Dublin City Council's Environment SPC yesterday.
It was also revealed the EPA issued non compliance notices over the dropping of temperatures to below an agreed level and the failure to notify them of the breaches in a timely manner.
In a statement to 98FM News, Covanta (which jointly operates DWTE) says "the matters referred to occurred during the early stages of commissioning. The company has since worked with the EPA to satisfactorily resolve these."
The cases come on top of the accidental release of lime on the 7th in which 11 workers were hospitalised as a precaution.
Burning has been suspended while separate investigations, one internal and two external, are carried out.
