Is fire retardant treated canvas safe?

[RocktheCasbah]

Hi! We just built our first yurt! It's beautiful and we love it, but when we moved in there was a strong smell. We went way out of our way to use natural building materials, natural stains and floor finish etc. And my heart sank when I asked the maker about the canvas which is Sunforger marine canvas, which is CPAI-84 compliant, meaning it's treated with fire retardants. I have an 8-month-old baby and pre-schooler and now I'm worried that the yurt isn't a healthy environment for them. Any experience with fire retardant treated canvas? Does anyone know what they use to make it fire retardant (a few long hours on the internet and I can't find anything about what chemicals they use to make it fire retardant). Is there a protocol for not getting this stuff into our bodies (like don't lick the yurt!)?Any advice would be most most welcome.
