There is high-temperature smoke in the fire scene, which is safer to protect people's eyes and ears; breathing masks effectively protect the respiratory tract and provide oxygen through the air delivery pipe. Due to the sudden fire, safety armor must be easy to wear. This product designs the air storage bag in the form of a vest, which only needs to be put in from the head and then put down the windshield. Helmet design can effectively protect the head.
