Results in Engineering, 32, 111694. https://doi.org/10.1016/j.rineng.2026.1116942590-1230https://hdl.handle.net/11268/17398Smoke generated during a fire modifies light propagation through absorption and scattering processes caused by suspended particles, reducing visibility in indoor environments. The optical characterization of these aerosols is relevant for analyzing how different smoke conditions affect light distribution and visual perception in spacesequipped with emergency lighting systems. This study is limited to the experimental conditions considered and does not aim to establish a universal model for the optical behavior of fire smoke. Nevertheless, the proposed methodology provides a useful framework for combining experimental optical characterization and lighting simulation in smoke-filled environments.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Ciencia y aeroespacialjournal article10.1016/j.rineng.2026.111694open accessCiencias físicasÓpticaIngeniería de la producciónGoal 9: Build resilient infrastructure, promote sustainable industrialization and foster innovationGoal 11: Make cities inclusive, safe, resilient and sustainable
