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 ...

Pressure Relief Valves (PRV’s) are devices used to release pressurised fluid from a wide variety of Pressure Vessels. PRV’s are used to maintain optimal pressure within a system, thus protecting the vessel from becoming overpressurized which can potentially cause damage or failure of a vessel. Pressure build-up related damage can be costly as well as a health and safety risk. PRV’s act as the main safety mechanism of a pressurized system (see ...
Champion Driver Mat Kennedy does it again at Bunbury. Bunbury Speedway has been a happy hunting ground for the TKR Team in recent meetings. Mat recently won his 3rd Feature in succession at his favourite Bunbury Track.
Wire ropes used in cranes & hoists for lifting purposes will experience deterioration throughout their entire service lives. Deterioration occurs through two principal mechanisms, namely, external and internal fatigue, which is caused by bending over sheaves or drum windings and crushing, which is caused by multilayer drum spooling. Another major cause of deterioration in a wire rope is the lack of lubrication.
What is external and internal fatigue?
During its operational life a wire rope is exposed to repetitive bending stresses. This will ...
Crane failures continue to dominate the headlines, with several incidents that have occurred over the last few months. Many of these incidents are a result of overloading the crane or operating the crane outside of its working envelope.
Operating any crane beyond its rated capacity has the potential to cause a catastrophic failure of the crane, its support structure or both due to associated loss of control of the load. When control of the load is lost, workers ...
According to the Canberra Times, a tragic incident happened at a public hospital worksite in Canberra, when a 62-year-old construction worker was struck by a crane boom and died at the scene. The incident happened when a mobile crane was moving a large generator at a low height and rolled onto its side. It appears as though the boom of the crane, which was lifting the generator has struck the man when the crane rolled.
Ten co-workers rushed to ...
Unfortunately another fatality occurred on a minesite when a boilermaker working inside a thickener tank died when the gantry bridge above him failed and collapsed, crushing and pinning him.
The WA Department of Mines have issued a Significant Incident Report with details of the incident and Actions required. See attached SIR 244. AME can assist with your required actions.
Plant structural integrity continues to be a major concern in the industry, not just in Australia, but overseas as well. In Western ...
There have been numerous incidents with the storage of portable LPG gas bottles. In a recent freak incident in Sydney, a 15 year old boy is in a critical condition with "horrific burns" after a leaking 9kg gas bottle in the boot of a car exploded when the driver lit a cigarette and the car burst into flames.
The teenager was walking past the car when the gas bottle exploded. He was knocked to the ground and suffered critical head ...
