Okay.
I have a couple more questions.
There has been some discussion about the building materials aspect. I do come from the municipal sector, so I find that one rather intriguing. You talk about the fire safety ratings. You talk about laminated products, and so on.
I understand when you're talking about the building code, and structurally it might be fine, and the rating might work in terms of fire safety rating, but when you start getting into something like laminated products, and so on, how will that translate into toxicity? What is it that's going to come out of that which could actually be harmful to someone over and above the smoke being harmful? Has that been part of the process you have been undertaking to understand?
