Summary
This safety flash examines three incidents involving an unverified slip-ring isolation, a scaffold plank falling when a roller box opened, and workers exposed to moving machinery. It identifies assumptions and incomplete work-control documentation, emphasising completion of authorisation processes, verification of safeguards and speaking up to stop unsafe work.
Classifications: Dropped objects; falling objects; DROPS.
Classifications: Electric shock; electrocution.
Classifications: Human factors; human performance; ergonomics.
Classifications: Control of work; work control.
Classifications: Energy and process isolation; isolation; energy isolation.
Classifications: Permit to work; PTW; work permit.
Classifications: Stop-work authority; stop work; stop-work intervention.
Summary
Serious control of work related accidents and near misses, in which a common cause across them all was seen to be ASSUMPTIONS being made without VERIFICATION checks being performed.
IMCA SF 17/22. Themes: control of work, electrical safety, isolation, permit to work.
