We evaluated a skylight fall hazard using an “attention conspicuity” measure, in which observers detect and identify hazards in brief presentations of photographs taken from a skylight accident site. Hazard detection and object identification varied with the scene and indicated that the flat-panel warehouse skylights were not conspicuous. A second experiment replicated these results and demonstrated that longer viewing time (3 sec vs. 15 sec) did not improve detection of the skylight, but did increase detection of other hazards. These results suggest that assessment of conspicuity using a quick hazard detection technique may be valid and efficient.
