How does the CBA ensure safety when apprentices work with secondary voltage?

The choice that indicates the importance of direct oversight by a qualified leader is particularly relevant when apprentices are working with secondary voltage. This approach is crucial because working with electrical systems can pose serious safety risks. A qualified leader has the experience and knowledge necessary to provide real-time guidance and supervision, ensuring that apprentices adhere to safety protocols and understand the intricacies of the tasks they are performing. This oversight helps to mitigate the risk of accidents or injuries that could occur from a lack of experience or understanding among apprentices.

On the other hand, while protective equipment, checklists, and teamwork can contribute to safety, they cannot replace the necessity of direct supervision by a qualified professional. Protective equipment must be used correctly, checklists must be followed diligently, and teamwork must be effective; however, without the direct oversight of someone with the requisite qualifications, these safety measures may not be implemented effectively, significantly increasing the risk associated with working with secondary voltage.
