BUSINESS 1 2 1 & 2: Sufficient exercise and proper nutrition can help to minimise fatigue. While the technology originated in the US, the development of PRISM product has been matured in the South Africa mining industry. Currently, PRISM covers 4 500 mining personnel in some of the largest mining operations in South Africa, including Kumba Iron Ore- owned Kolomela iron ore mine. The company projects that this will expand to over 10 000 mining personnel by the end of 2018. Karin Van Huysteen, Occupational Health and Wellness manager with Kolomela Anglo American, says, “It’s important to realise that the mindset of ‘It’s never going to happen to me’ needs to change, and it’s difficult to do that. But by getting people used to this system, where it actually predicts that something might happen, it makes them realise there are silent symptoms that they should look out for.” PRISM provides a dashboard for supervisors that shows the fatigue status of their entire workforce. The system constantly updates the status of each employee. PRISM even notifies supervisors of the employees who may soon be entering a more significant state of fatigue. The alert goes to the individual and/or supervisor through the work environment’s existing communication system, either as a text message or via dispatch. Whether companies choose to implement technology to assist them in their fatigue management, ultimately the aim is to ensure that employees are educated regarding the causes and symptoms of fatigue, as well as the possible effects, including increased incidence of accidents and injuries. Noting – and managing – their own fatigue levels need to become part of not only the employee’s routine, but also the site’s safety culture. ■ Results after Implementation of Predictive Safety’s PRISM monitoring system.
