What must an inspector issue if a trainee is found working without supervision?

The correct response indicates that a completion form must be issued if a trainee is found working without supervision. This requirement exists to ensure that the training process is properly documented and to maintain adherence to safety, regulatory, and industry standards.

Issuing a completion form serves as a formal acknowledgment of the trainee's status and can help track their progress in the training program. It also emphasizes the importance of supervision during the learning phase, ensuring that trainees have the necessary guidance and oversight while they develop their skills. This action contributes to maintaining safety standards within the workplace, as unsupervised trainees may not be adequately equipped to handle tasks independently.

Other options do not fulfill this specific need. A warning notice, for instance, typically pertains to violations of regulatory compliance but does not directly address the documentation of training progress. A temporary work permit usually allows someone to work in specific circumstances but is not necessarily relevant to trainee supervision. An instruction manual may provide guidance on tasks but does not serve as a formal record of training status. Thus, issuing a completion form is the appropriate course of action in this scenario.
