Final answer:
The root causes of the incident could include a lack of training, failure to use personal protective equipment, poor scaffold maintenance, and insufficient supervision.
Step-by-step explanation:
In this case, the incident of a worker falling off a scaffold and breaking their leg can be attributed to several potential root causes. One possible root cause could be lack of proper training and education on how to safely work on scaffolds. If the worker did not receive adequate training on how to use the scaffold and the safety precautions to take, they may have been unaware of the risks involved or the correct way to secure themselves. Another root cause could be failure to use personal protective equipment (PPE) such as safety harnesses or helmets. If the worker did not wear the required PPE while working on the scaffold, it could have increased their risk of falling and sustaining injuries.
Additionally, poor scaffold maintenance and inspection could have played a role in the incident. If the scaffold was not properly maintained or regularly inspected for any defects or weaknesses, it could have been structurally compromised and more prone to accidents. Insufficient supervision and oversight could also be considered as a root cause, as the worker may not have been adequately monitored or guided while working on the scaffold.
