抄録

<p>During tunnel fires, since the tunnel space is filled with smoke, the environment where the user can act quickly to a safe space such as an emergency exit is required. Especially when a tunnel section is small, the measures to support evacuation guidance is considered to be important. Because there is a possibility that the smoke descent from fire outbreak at an early stage.</p><p>So, in this research, in order to investigate relationship between interval[m], luminance[cd/m2] and Cs[m-1] through smoke, the luminance measuring test through smoke was conducted on the guidance light. In the previous experiment, the luminance measuring test through smoke using white smoke (smoke machine) and black smoke (black smoke candle) in a tent is conducted. Even under the same smoke concentration, the measurement luminance is slightly smaller in the black smoke.</p><p>Therefore, in this paper, we focus on the type of smoke and the measurement distance, and report on the result and consideration of the luminance measuring test through smoke by fuel combustion in a vinyl house installed in a full-scale tunnel.</p>
