Safety Upgrade Initiative for Production Machines

This technical report outlines a safety upgrade initiative aimed at enhancing the safety of critical production machines that previously did not meet safety standards. The project involved implementing safety functions based on a detailed risk assessment conducted by the customer, which identified various hazards and hazardous situations. The report details the challenges faced during the multi-million dollar project, including COVID-related plant shutdowns, increased production demands, and supply chain issues that caused significant delays. It describes the systematic approach taken to define, design, program, verify, and validate safety functions for each critical machine. The upgrades included replacing obsolete drives and implementing safety measures to address various hazards. Throughout the five-year project, the focus remained on maintaining quality and consistency despite external influences. The report concludes with the successful implementation of safety upgrades and the establishment of a strong customer relationship, leading to further safety upgrade projects.
