Analysis of Viewing Zone Effectiveness Across Laboratory Configurations. The heatmap shows detection rates of warning signs across four laboratory disciplines and four location types, measured with eye-tracking and detection tests (n = 48). Warmer colors indicate higher visibility. Results highlight strong context effects, with the lowest visibility in chemical lab shared equipment areas (62.0%) and the highest in chemical lab entrance zones (91.0%).
