Summary
A buckle detector weighing approximately 25 kg was expelled from a pressurised pipeline during retrieval, landing approximately 2 m away and coming close to two crew members. The flash identifies unassessed back pressure and inadequate task planning, and describes stopping operations, exclusion barriers, sling retention and consideration of revised risk assessments.
