Mr. Eoin O'Dowd:

For certain buildings over the 15 m mark, there is a requirement of a reaction to fire classification of A2 unless you have that test. We understand the question of smoke toxicity is being examined. It was examined by the European Commission in 2017. It looked at smoke toxicity as an essential characteristic of products under the construction product regulations. Along with other recommendations from that report, it recommended that it would be beneficial to look at it as a pan-European system. We are aware that smoke toxicity is being examined as part of an ongoing review to improve document B – the TGDB counterpart. We will be paying close attention to this research and we will also commit to further examine the question of smoke toxicity in construction products as part of our own fire safety research group.
