Objective: The study investigates the feasibility of evaluating a worker’s Fitness-For-Duty (FFD) status using human bio-signals such as, Electroencephalogram (EEG), Electrocardiogram (ECG), and Galvanic Skin Responses (GSR). Background: Current FFD programs, in nuclear industries, focus on drug & alcohol testing and fatigue management. However, there are limitations in current FFD measurement technologies: time-lag detection, subjective and potentially biased evaluations. An alternative to solve these problems is using bio-monitoring technologies. These technologies make it possible to monitor the physical and mental state of a worker. Method: A pilot experiment was performed to investigate the feasibility of monitoring a worker’s fitness status. The resting states (Eye closed and Eye Open) of EEG, ECG and GSR were recorded on 68 subjects (35 Normal status subjects, 21 Alcohol-use subjects, and 11 Sleep-deprived subjects). Using time and frequency domain analysis, the collected bio-signals were analyzed. As a result, 48 bio-signals were identified as potential indicators for FFD. Based on using the 48 variables, feasibility of classifying a subject’s fitness status into one of the following categories was examined by using statistical analysis: Normal, Alcohol-use, and Sleep-deprived. Results: The results identified 35 bio-signal indicators with significant p-value differences when comparing the normal group to the unfit (Alcohol-use and Sleep-deprived) group. Conclusion: EEG and ECG indicators are the main attributing factors when determining a worker’s FFD. Application: This FFD evaluation method can be applied to high-reliability systems (e.g., military, aerospace as well as nuclear industries).
