とることができるのである。Examples of odor components include odor components such as mercaptan which are harmless to the human body and which are contained in a very small amount in city gas and are non-reactive with carbon dioxide gas for detection. Further, the coloring component is a component that is colored in an appropriate color by being dispersed in the air in the form of fine particles such as smoke.These components mix with carbon dioxide gas and flow according to the flow of carbon dioxide gas. The mixed airflow has an odor and / or a color, and its state and direction can be detected by a person's sense of smell or sight, so that a quick evacuation activity can be taken.
