Oh, from the firefighting industry.
A lot of new products are tested with NRC and go through rigorous.... They literally burn these products and they have to have one- or two-hour fire resistance before they are approved. There is quite rigorous testing.
I think a lot of the problems with the firefighters started with the I-joists in homes; that's a smaller, stick frame built component. But as we move into mass timber and then these larger structures, they just char, as Iain mentioned, and they are safe.
Chief Len Garis in B.C. has done a lot of studies on how products are evolving and the precautions put in place. It has been amped up. I know there are even new glue products, too. The industry is working on this.
