BackgroundThe Department has received numerous reports of failed and damaged equaliser cables on vehicle hoists, including those types with two or four posts.
The equaliser cables are typically made using steel wire rope and are used to keep the hoist level during raising and lowering. Over time, equaliser cables can stretch, fray, corrode, crack or break and therefore should be regarded as a wearing component.
Inspection and testing on equaliser cables should be carried out by competent persons, such as ...
Summary of incident
In June 2018, a scaffolder fell while crossing a void 5.7 metres above the ground. The scaffolder was wearing a fall arrest harness with a retractable type lanyard connected to a horizontal guardrail of a scaffold platform. When stepping 1.3 metres laterally to access a pipe support structure, the inertia reel mechanism of the lanyard engaged, impacting the scaffolder's balance. This caused the scaffolder to fall backwards through the void and swing against the scaffold structure. The webbing on ...

Mines inspectors repeatedly identify plant such as shaft reliners, hopper trolleys, workshop mobile jib cranes and other multi-purpose lifting devices in poor condition and without maintenance and inspection records. These are classified plant as defined in regulation 6.1 of the Mine Safety and Inspection Regulations 1995 (MSIR). For plant with a lifting capacity over 10 tonne, they are registerable as required by MSIR r. 6.34. All others are subject to duty of care requirements under MSIR r. 6.2.
Subject: Structural failure of fixed conveyor stacker

Summary of incident
Note: The Department of Mines, Industry Regulation and Safety’s investigation is ongoing.
The information contained in this significant incident report is based on materials received, knowledge and understanding at the time of writing.
In February 2019, a fixed conveyor stacker collapsed during normal operation. Other than the temperature reaching 47°C, there were no extreme weather events at the time nor any abnormal operational loads. It was not running at full capacity at ...
Mobile Elevating Work Platforms (MEWP) are versatile items of Plant that can be used in a variety of applications. These items of Plant are designed with the intention of lifting people and have the possibility of causing serious injury or death if not operated or maintained in a safe manner.
Mobile EWPs shall be designed, manufactured, tested and inspected in accordance with AS1418.1: 2002 and AS1418.10:2011 and operated and maintained in accordance with AS2550.1:2011 and AS2550.10:2006. All mobile EWPs must undergo pre-operational inspections, routine ...
The term safe working load (SWL) has been the cornerstone of engineering, particularly with regard to load carrying equipment, for many years. It was generally considered to be the minimum breaking load of a component divided by an appropriate factor of safety giving a ‘safe’ load that could be lifted or be carried.
In Australia the use of Safe Working Load (SWL) for cranes, hoists and winches was universally used throughout all industries and referenced in legislation and the Australian Standards.

Additional notes to Mines Safety Bulletin No 125 - Pneumatic Press Filters
Written by AME Operations Manager, Steve Ansell.
Following on from the Department of Mines and Petroluem's Mines Safety Bulletin No 125, issued on 24 September 2015, it's imperative to acknowledge that all pressure equipment has the potential to harm personnel or damage other equipment.
It’s worth noting that the Mines Safety and Inspection Regulations 1995 (MSIR 1995) state by definition that any pressure vessel is classified plant and therefore needs to ...
The Mines Safety and Inspection Regulations (MSIR 1995) provide comprehensive guidelines for the inspection and safety of plant, however they are often misinterpreted, which could mean your site has been left non-compliant.
One such commonly misinterpreted and incorrectly applied inspection regulation is that of the time period between statutory inspections of Air and Gas Receivers.
The question: Do Air or Gas Receiver’s less than 150 litres need Statutory Inspections?
The Mines Safety and Inspection Regulations (MSIR 1995) states in Regulation 6.40 (1) that ...
You may have Classified Plant Record Books, but are they set up correctly?
AME have become aware that whilst some sites are improving on maintaining plant records – the record books themselves are not always compliant with industry standards.
By law, under Reg 6.40(2) of the Mines Safety and Inspection Regulations, inspections of registerable classified plant must be recorded in a classified plant record book kept for that purpose at the minesite.
The details of the inspection, including the date of the inspection and ...
Root Cause Analysis (RCA) is an inspection technique performed to identify all the contributing factors in an incident and determine the root cause for why a failure occurred. AME have a simple but very effective methodology for determining the actual root cause of an incident.
Whilst identifying and fixing the failure that has led to an incident is necessary, isolating the root cause is essential to preventing reoccurrence. Jumping to conclusions without further detailed Root Cause Analysis can prove very costly in ...
