The answer is, yes, in some cases. I'll give you an example for when you talk about combustible materials.
California put out a regulation called TB117-2013. It was a technical regulation that had an impact on the smoulder test for mattresses. Even though the regulation only applied to California, it affected the whole North American market. It changed the way the testing was done and what materials could be used.
Originally, you had various materials injected into the mattress to prevent it from flaming up, but California said, “We don't want any of those because they cause cancer.” It has changed totally the way that manufacturers buy products and combine them to meet these various tests. These types of tests occur in different places across North America, and depending on where you are exporting to, you need to match them.
Local fire departments play only a small role, though, because you're trying to meet criteria that in many cases are established provincially, federally, or for all of the North American market.
