Culture Minister Caral Ni Chuilin gave evidence for the Culture Committee's inquiry into the Casement Park GAA stadium redevelopment from 10am.
Officials briefed the committee on the Community Resuscitation Strategy.
Representatives of the Youth Justice Agency briefed the Justice Committee about a revised approach to custodial arrangements for children, from 3pm.
David Hilditch of the DUP says there is a "substantial list of documents which say that safety was an issue at the Casement project" from about 2013.
He describes it as "worrying" that the minister was not made aware of it.
"Is it not concerning that senior Department of Culture, Arts and Leisure (DCAL) officials and perhaps SportNI have kept quiet, hidden, or even covered up some of these serious matters," he asks.
Mr McCausland further presses the minister as to whether discussions about safety had mentioned emergency exiting as a problem.
"Absolutely," she replies.
"But it was not an issue that meant that advice that was given was ignored, or suppressed.
"It wasn't that it was an issue that needed to be brought up to a level for my attention.
"I want to make this clear at no time did anyone tell me that there was a Hillsborough-type scenario in waiting and I did nothing about it."
Paul Scott addresses the committee on 30 April
On 30 April, safety expert Paul Scott told the Culture Committee he was put under "undue pressure" to approve plans for the new ground by officials from the minister's department.
He also said he had made a complaint of bullying against them.
Mr Scott, of the Safety Technical Group (STG), said pressure exerted upon him had been "so significant" he had no choice but to raise a complaint.
He told the committee that he had been expressing concerns about the stadium design for two years.
Mr McCausland asks the minister when she first became aware of concerns over the safety of the stadium design in relation to emergency exiting.
"In relation to the allegations that Mr Scott made to this committee about a Hillsborough-type concern, the first I heard of it was on the 30 April, "Ms Ni Chuilin answers.
She says she would have expected that "any real and pressing concerns" would have been raised with officials at earlier meetings.
Ms Ni Chuilin says an independent investigation will be taking place into whistle blowing in light of "grievances raised" at the committee on the 30 April.
"We are very sensitive to the duty of care to protect and support the people who have raised concerns," she says.
The Culture Minister, Caral Ni Chuilin, says that for her, "safety is always paramount in the delivery of the stadia programme".
Ms Ni Chuilin says that she has asked her officials to review the project urgently and this will draw on experts in the field of public safety.
