Case Study: Gold Fields South Deep Mine achieves rapid ISO 45001 certification and digitized EHS oversight with IsoMetrix

How Gold Fields’ South Deep gold mine embraced digitization to improve its safety culture, and achieved ISO 45001 certification in record time

Gold Fields South Deep Mine, a Gold Fields operation with about 4,500 employees in South Africa, faced an outdated, manual approach to health and safety that relied on spreadsheets, produced siloed and incomplete data, and hindered timely, auditable reporting and clear accountability. To modernize its EHS management and improve safety culture, the mine selected IsoMetrix and implemented IsoMetrix’s Environment, Health and Safety (EHS) software.

IsoMetrix delivered a centralized, standardized EHS platform with features such as a Central Action Manager, dashboards, a training register and a central procedures repository, giving managers real-time oversight and clear accountability. As a result, Gold Fields South Deep Mine achieved ISO 45001 certification within five months, improved reporting accuracy and auditability, increased contractor compliance and employee understanding of risks, and now measures EHS performance and controls consistently across the operation.
