Hier einige Exzerpte von Artikeln über die Untersuchung der Todesfälle:
Hypothese 1 zur Ursache Geschrieben von The Irish Times:
Mr Murray and Mr OShaughnessy had entered the burning building through a blue corner door at the other end and were attempting to fight the blaze with foam.
Flashover
Dr Mansi concluded that at 11.08 on the morning of the fire, there was a partial flashover, an event in which heat, radiated from the buildings roof down into dense smoke, caused the smoke to ignite. While such an event begins suddenly, it progresses slowly over several minutes, he explained.
Conclusion
Your conclusion is that the conditions inside [the building] were conducive to a partial flashover? asked the coroner, Dr Brian Farrell. Yes, said Dr Mansi.

Hypothese 2 zur Ursache Geschrieben von The Irish Times:
Mr Large said he felt there were inadequacies, inconsistencies, and inaccuracies in the work of Dr Peter Mansi, a forensic fire investigator retained by the Health and Safety Authority which, along with the Garda, gathered evidence that led to the criminal case against the Council.
He disagreed with Dr Mansis theory that a partial flashover was the probable significant event in the fire that contributed to the mens deaths. He on the other hand had come to the hypothesis that the two fire fighters, who had been ordered to remain just inside the building but moved forward, disturbing some flammable liquid which then engulfed them and killed them.

Gerichtsmedizinische Untersuchung Geschrieben von The Irish Times:
Toxicology tests showed that neither man had alcohol or drugs in their system at the time of their deaths and neither had sustained trauma injury. There was no soot in their airways but both men displayed evidence of thermal damage to their air intake passages. Neither man was otherwise ill in any way.
Dr Curtis said the protective clothing worn by both men showed evidence of having experienced extreme heat that would provide an environment that didnt support life. Both bodies displayed evidence of having endured extreme heat and death, said Dr Curtis, would have been immediate or very rapid.
Dr Curtis was not able to say whether the catastrophic event that occurred was a fire flash-over, as claimed by an independent forensic fire investigator Dr Peter Mansi, or a fireball, as hypothesised by another expert witness, Christopher Large, giving evidence for Wicklow County Council.
In either instance, that would provide an environment which would not support life. . . there might have been a very brief period of heat discomfort, depending on how rapid the event was, and then there would follow confusion, coma and death very rapidly.
The protective clothing worn by both men showed signs of being exposed to extreme heat, he said. Pictures shown to the jury showed Mr Murrays fire fighters protective clothing charred and badly disintegrated. Mr OShaughnessys protective gear was damaged less severely.
Asked by William Hamilton, counsel for the Murray family, whether it was possible to determine the time of death, Dr Curtis said no and added that unconsciousness would have been extremely rapid and death would have followed.

Untersuchung der Schutzkleidung Geschrieben von The Irish Times:
Dr Vaughan said both sets of protective clothing had evidence of prolonged exposure to intense radiant heat.
Asked if this could have been caused also by a fire ball, he replied that the severe damage I have seen is not consistent with that but was consistent with exposure to radiant heat. Even a fireball of eight seconds duration would not necessarily cause the level of damage he saw.
People walk out of that, he said.
Dr Vaughan agreed with Luán Ó Braonáin, SC for Wicklow County Council, it was a reasonable assumption that there could have been a fireball at one stage in the blaze incapacitating Mr Murray and Mr OShaughnessy who were then exposed to radiant heat. However, was not possible to distinguish between a fire ball and a flash-over, said Dr Vaughan.
After some initiating event, said Dr Vaughan concluded in his and his colleagues report, the casualties were knocked down and totally incapacitated. The observed equipment damage then took place over an extended period during which time the casualties remained motionless.
Surface temperatures within the compartment where the men died would have been more than 400 to 450 degrees centigrade during efforts by colleagues to rescues them, causing skin burns to fire fighters within about 20 seconds he told the inquest.
Alan Ryan, a joiner and who had leased the property in which the men died, told the inquest that around 85 per cent of the space between the ceiling and the corrugated metal pitch roof was stuffed with wooden pallets and crumpled up, stiff brown paper. He assumed these had been put there by previous occupants, who were cardboard manufacturers, for insulation purposes.
The inquest has heard previously that radiant heat from above was a significant factor in creating what Dr Mansi says was a partial flash-over generating extreme radiant heat in the compartment room where the men died.
