Guardian Angel

A large amount of toxic gas is contained in the combustion products of fire, which is the main cause of fire death. The "Guardian Angel" is a rescue device with a built-in lighted exit sign. When a fire breaks out, by following the lighted sign, people can not only find their way to exit, but can also get a mask by pressing the sign to protect themselves from the deadly vapors. The masks also emit red light to provide illumination in smoky environment and can help rescue workers find targets in the moment.
