A snuffer is a tool used to extinguish flames or embers by cutting off their oxygen supply. It typically consists of a long handle with a cone-shaped or cup-like end that can be placed over a burning object to smother the fire and prevent it from spreading. The symbol "👃🔥" could represent the act of using a snuffer, where the nose (👃) signifies the action of sniffing or detecting the fire, and the fire (🔥) represents the element being extinguished by the snuffer.
