MDG41 is an industry based response to the increased number of fluid injection and related injuries being sustained in the mining sector. Mechanical Design Guideline 41 is a guideline published by the NSW Department of Primary Industry and is now recognised in other states. This is a reference document that should be used when reviewing plant risks in accordance with state Occupational Heath & Safety Acts / Regulations. MGD41 relates to fluid power systems at all mines (open-cut and underground), quarries, dredges, mineral extraction operations and associated plant operating above 5 MPa, (720 Psi) or 60 degrees Celsius. MDG41 also provides an effective medical protocol to be followed in the event of fluid injection injuries.

MDG41 fits into legislative framework as recognised "Best Practice" principles. Various state Occupational Health & Safety Acts require employers to identify, assess, eliminate or, control risks.

Parker Hannifin's products meet / exceed the specifications defined in MDG41 and the requirement for a "Matched System". A matched system is defined in MDG41 'where the hose and fittings (insert/ferrule) are from the same manufacturer and assembled and crimped using the method specified by that manufacturer'. Through ENZED TAFE certified training, we are able to meet the competency requirements defined by MDG41, both as assemblers and installers of hose and fittings. ENZED also offer recognised best practice testing to 2 x WP and tagging of hose assemblies (see definition 3.7.7.1 & 3.7.5) ensuring fluid power systems are reliable and fit for purpose. ENZED can also show you how to effectively establish your 'Hose Management' system in accordance with MDG41, section 7.6
