Using Smartphones for Indoor Fire Evacuation.

Fire smoke reduces the visibility of emergency direction signs, rendering them ineffective for providing appropriate guidance along evacuation routes in a fire situation. This is problematic because civilians may select evacuation routes that expose them to smoke or fire in a burning building. This study proposed using a smartphone voice-guided evacuation system (SVGES) to provide alternative evacuation routes for civilians trapped at a fire scene.

Wayfinding of Firefighters in Dark and Complex Environments.

Firefighters searching in dark and complex environments might lose their orientation and endanger themselves at the fireground. This study conducted experiments in the Training Facility of the New Taipei City Fire Department (NTFD), Taiwan. The objective of the experiments was to analyze the profile of each firefighter by a 13-factor self-report survey and their wayfinding time in dark and complex environments (DCEs).

Underground Pipeline Leakage Risk Assessment in an Urban City.

Underground pipeline safety is a concern among civilians in populated urban cities. Due to the potential for considerable damage from underground pipeline leakages, it is critical to identify potential risk areas. This study developed a simplified risk value using risk assessment software (ALOHA) and geography information systems (SuperGIS and Surfer) to produce potential risk maps for underground pipeline leakage in a major urban city.
