What equipment management list indicates items the custodian has signed to accept responsibility?

The Custody Receipt/Locator is the correct answer because it specifically serves as a formal record indicating that an individual, typically a custodian, has accepted responsibility for certain items or equipment. This document includes details about the items being assigned, such as serial numbers and descriptions, and requires the custodian's signature as acknowledgment of their responsibility.

By having a signed Custody Receipt/Locator, the organization can maintain accountability for its equipment assets, ensuring that custodians are aware of which items they are responsible for and can track the movement and status of these items over time. This is critical in aerospace medical services, where proper equipment management is essential for operational readiness and compliance with safety regulations.

The other options relate to different aspects of equipment management. The Master Task List is a planning tool that outlines tasks or responsibilities, but does not serve to document equipment responsibility. The Equipment Action Request is typically used to initiate actions such as maintenance or inventory requests and is not focused on custodial responsibility. The Turn-in Transfer List is more about the process of returning equipment rather than documenting acceptance of responsibility.
