SIR No. 276: Fall from height after failure of retractable type lanyard

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 ... Read more

Identifying the Right Pressure Release Valve Thread Type

Onsite – size identification of BSP and NPT fittings Thread types 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 ... Read more

Are your Crane & Hoist Wire Ropes in good, serviceable condition?

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 ... Read more

Crane Incident Compilation

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 ... Read more
