Who must appoint qualification/certification board members in writing?

The correct choice is the Commander or Officer in Charge, as they hold the authority to appoint qualification and certification board members in writing. This responsibility often falls within their mandate to ensure that personnel are properly assessed and qualified according to both regulatory standards and organizational needs.

The Commander or Officer in Charge typically possesses the necessary oversight and command authority to ensure that the qualifications of board members align with the mission and operational requirements of the unit. They understand the importance of having appropriately skilled and knowledgeable personnel on these boards to maintain high standards of training and operational readiness.

In contrast, while the Training Officer may be responsible for the training and educational aspects of the personnel, they do not usually have the authority to make formal appointments without the commander's oversight. Similarly, a Human Resources Manager's role revolves more around personnel administration than the specific qualifications or certifications pertaining to technical roles. The Safety Officer focuses on maintaining safety protocols and operational safety rather than appointing qualification boards. Thus, their roles, while important, do not encompass the authority required to formally appoint members for these boards.
