This looks like a sensible discussion. On the other thread mentioned earlier, we talked about how all clothing is flammable, burning at different rates. Watchdog wants fancy dress clothing to be subject to the same rules as the Nightwear law. But all that would mean is that fancy dress, like nightwear, would either be made from cotton treated with flame retardant chemicals or from polyester. The principle of the Nightwear law is to preserve life, not to make clothing non-flammable, which isn't really possible. The law says nightdresses must be made flame resistant, but it's optional for pyjamas. The result is that most children's nightdresses are made of polyester because that's allowed - on the basis that it burns very quickly, and most pyjamas are cotton but untreated. Polyester nightdresses mean a child can be badly burned but should at least live. By contrast, cotton burns longer, essentially, so it can be fatal when set alight. If you want cotton nightdresses, they will have to be treated with flame retardant chemicals. And if you want all clothing to be safer, then you'll need even more chemicals, lots more in the case of some materials.
So, we need to be wary of people campaigning for tougher flammability laws because that would please the flame retardant industry no end. The same industry succeeded for decades to get loads of chemicals into US furniture that turned out to not be needed. After long campaigning by consumers and fire fighters over there, they've now changed the law so there should be no chemicals in US furniture soon.
