In March 2016, two servicemen were working in an integrated tool carrier (IT) work basket removing pipe services from the sidewall and backs of an extra-high excavation.
At the time of the incident, the work basket had been raised close to the backs but extra lift was needed and the basket was tilted upwards. A worker who was leaning over the front of the basket received serious head injuries when crushed between the top rail of the basket and the backs.
Direct causes
The worker was leaning over the front of the basket when the basket was tilted upwards.
Contributory causes
- Lack of effective communication between personnel.
- The injured person was new to the task and was undergoing training.
- Tilting of the work basket was not included in the training documentation.
- The operator directing the work basket was not aware of the position of the offsider when the direction was given to tilt the work basket.
- The operating procedure did not identify the potential for a crush hazard while conducting work from the basket.
