This research explored the potential of smart wearables to enhance safety in water utility operations – an area not yet widely studied. These technologies offer real-time, individualised monitoring of fatigue, heat stress, vital signs and environmental conditions, helping workers better understand and manage risks. 

The project trialled a mix of established and emerging sensing technologies across three sites in South Australia. Data was collected through wrist-worn actigraphs (tracking sleep and activity), smart shirts (monitoring heart rate and exertion), and motion-sensing insoles (assessing gait). These were complemented by environmental measures such as temperature, humidity, light, noise, thermal imaging and in-vehicle monitoring. Interviews with 21 employees provided insights into work practices and perceptions of safety. 

The study demonstrated that smart wearables can effectively model physiological stress linked to different work practices, equipment choices and planning decisions. The research highlights the value of integrating wearable technologies into safety systems for water utilities. It supports proactive risk management and offers new opportunities for improving worker wellbeing and operational safety.
