Where should printed copies of the ECCM be maintained?

The correct choice for where printed copies of the Emergency Casualty Control Manual (ECCM) should be maintained is the Main Control. This location serves as the central command area for managing emergencies and operational control. Having the ECCM readily available in Main Control ensures that personnel in charge can access critical procedures and guidelines quickly during an emergency situation, thereby facilitating an efficient response.

Main Control is often staffed continuously during operations and represents the main hub for decision-making and communication. In contrast, while other locations such as repair lockers and the DCC may have access to operational materials, they are not the primary command centers for emergency situations.

Engineering Assist Locations may deal with specific engineering tasks, but they do not serve as the immediate control point for overall casualty response. Therefore, the Main Control is the most strategic place for maintaining the ECCM to ensure it is accessible when it is needed most.
