Which of the following is NOT a primary responsibility of the Commanding Officer regarding elevator systems?

The choice indicating that operating elevators is not a primary responsibility of the Commanding Officer is correct because the Commanding Officer's role primarily focuses on oversight, compliance, and the establishment of protocols rather than hands-on operational tasks. The Commanding Officer is responsible for ensuring that the elevator systems are managed effectively, which includes establishing qualification programs for personnel who operate the elevators, ensuring safety compliance with relevant regulations and standards, and training personnel to adhere to these protocols.

The Commanding Officer's responsibilities are strategic and managerial, ensuring that proper procedures are in place for safe operation, while the actual hands-on operation of the elevators is typically the responsibility of trained personnel or operators. This delineation allows the Commanding Officer to focus on safety and compliance rather than daily operational tasks.
