Abstract

This study describes a newly developed Core Temperature Visualization System (COTVIS) and functionally tests the system, designed to improve safety among construction workers. COTVIS functions as a Peer Awareness Alert System (PAAS), enabling real-time visual alerts based on biometric data, specifically heart rate and core body temperature. Unlike existing wearable technologies that rely solely on individual awareness, COTVIS shifts the responsibility for intervention to the entire crew by displaying alerts visible to nearby workers and within Bluetooth low energy distance to the triggered COTVIS. This approach addresses a critical need where individual risk perception often limits the effectiveness of safety measures. Testing in controlled environments demonstrated that COTVIS can potentially be used as a deterrent to safety-related injuries and illnesses and be an advanced alert system for injured workers. The findings suggest that with further development and field testing, COTVIS could be an integral component of broader site safety strategies.
