I found this fire escape mask in the wardrobe in my hotel room in Shenzhen. I think it is actually a pretty good idea. Many people who die in fires are victims of smoke inhalation so a mask like this would seem to be a valuable addition to life safety. Looks like it is manufactured by "Guangdong Coal Mine Safety Apparatus Factory". I'm surprised I haven't seen anything like this in US hotels. At the very least it would help keep your eyebrows from getting burned off.
