A worker suffered serious injuries after becoming trapped when the sides of a trench collapsed during excavation work.
Emergency services were called to the scene and the worker was rescued from the excavation before being taken to hospital for treatment. Investigations are underway to establish the circumstances surrounding the collapse and whether suitable excavation controls were in place.
Trench collapses can occur suddenly and without warning. Even relatively shallow excavations can become unstable, trapping workers beneath tonnes of soil within seconds. Factors such as ground conditions, weather, vibration from nearby activities, and inadequate support systems can significantly increase the risk.
Employers should ensure that excavations are properly planned, risk assessed and supervised. Suitable protective measures, such as trench boxes, shoring systems or battered back sides, should be used where necessary. Excavations should also be inspected by a competent person before work starts and at regular intervals throughout the project.
Key safety message: Never enter an unsupported excavation. Proper planning, inspection and ground support systems can prevent potentially fatal trench collapses.
