TG4 is broadcasting a documentary on last year's tragedy in Creeslough, Co Donegal, after it had "carefully considered all of the important and sensitive issues raised".
Yesterday Áine Flanagan - partner of Robert Garwe and mother of Shauna Flanagan Garwe, who both died in the blast - requested that the programme not be broadcast.
Ms Flanagan's brother Killian had also contacted the broadcaster and gardaí to request the programme not go to air while the garda investigation into the explosion is under way.
In a statement issued this evening, the broadcaster said the programme would air, after it had "carefully considered all of the important and sensitive issues raised with us".
The broadcaster said the programme - "Iniúchadh TG4 - An Craoslach" - was about the ordinary people who assisted in the rescue at the scene before emergency services arrived.
It contains interviews with some of those who risked their own lives to bring others to safety.
The broadcaster said that the programme does not report anything about the victims "other than what has already been reported publicly in the direct aftermath of the tragedy".
Speaking on RTÉ's Liveline yesterday, Killian Flanagan had said that families were not consulted about the programme, adding his sister found out from an online article, and has barely slept since.
He said that the idea of TG4 airing the documentary now was "beyond comprehension" and asked why it could not air in six months' time instead.
This afternoon, Taoiseach Leo Varadkar told the Dáil he had hoped that "at the very least" TG4 would "consult" with the families of those killed, and then make a decision as to whether to "postpone" the programme.
Mr Varadkar said that he would be reluctant for the Government to issue a direction on this but asked TG4 to hear the families' case.
He was responding to Sinn Féin TD Pearse Doherty, who said that families of those who were killed in Creeslough were "pleading" and "begging" that TG4 not show the documentary as the issue was "too raw".
