“We’re making merchandise extra poisonous to make them extra fire-resistant by including chemical compounds to them.”
In his 2023 joint review into building merchandise with lawyer Anneliese Day, Morrell raised considerations a few lack of a basic requirement for testing product toxicity within the occasion of fireside. The assessment stated there was a “broadly held view” that producers add doubtlessly poisonous chemical compounds to merchandise to enhance their hearth efficiency.
Building product toxicity was considered one of two “stunning” omissions, in line with Morrell. The opposite was that he anticipated extra about how the business ought to be taught classes from disasters, a difficulty he stated was separate from the regulator. Each strains of questioning “could properly have been past [the inquiry’s] phrases of reference”, he added.

“I don’t know if the regulator for offsite fabrication earlier than it will get to website is the OPSS [Office for Product Safety and Standards] or the BSR [Building Safety Regulator].”
Of their impartial assessment, Morrell and Day advisable that the federal government and business handle the particular hearth dangers of recent strategies of building, together with flamable supplies inside structural frames and voids between modules.
