MDG-41 is a published guideline developed to address safety risks associated with high-pressure fluid power systems, particularly in mine sites. Its primary objective is to minimise the risk of injuries and fatalities caused by hydraulic system failures, including high-pressure fluid injection incidents, which can result in severe burns, lacerations, amputations, or death.
The guideline provides best practices for the design, installation, operation, maintenance, and decommissioning of fluid power systems. It applies to a wide range of equipment, including mobile plant, longwalls, mining machinery, construction machines, and fixed installations, covering systems operating above 5 MPa or 60°C. MDG-41 also emphasizes the importance of competent personnel, proper training, and risk-based control measures to ensure workplace safety
