Human-machine interface safety in construction: Protecting workers and equipment

The operation of heavy equipment on construction sites presents one of the most significant safety risks in industrial projects. In order to address these challenges and enhance both safety and efficiency within the Fadhili Increment Projects Department, a comprehensive Human-Machine Interface (HMI) safety system has been implemented. This multi-layer system integrates multiple advanced measures to enhance operational efficiency and improve personnel protection across all construction activities. First, a strict "No Foot-on-Ground" policy has been established to prevent personnel from entering active equipment zones, thereby reducing the risk of human-machine interaction during critical operations. Second, equipment alert technologies have been introduced to enhance real-time awareness for operators. Third, proximity warning alarm systems (PWAS) are used to alert workers and operators when they are in close proximity, helping to prevent potential collisions. Additionally, rear-view closed-circuit cameras (CCTV) systems have been installed on vehicles to improve visibility and support safer movement in complex environments. Finally, targeted hazard identification training has been provided to heavy equipment operators and flagmen, ensuring they are equipped to recognize and respond to potential risks. Combining advanced technologies with well-defined safety protocols, Fadhili team has set a new standard for construction safety and operational excellence within Saudi Aramco’s project portfolio
