Which action is necessary to prepare dummy items for stowage?

Preparing dummy items for stowage involves several critical steps to ensure safety and compliance with explosives safety regulations. Labeling each item with hazard symbols is essential as it communicates the type of hazards associated with the items, thereby promoting proper handling and awareness among personnel. This labeling helps in maintaining a safe work environment and ensures that everyone is informed about the potential risks associated with each dummy item.

Cleaning all items is another critical step; it prevents contamination and ensures that no foreign materials are present that could pose risks during handling or stowage. The cleanliness of items is particularly important in a shipboard environment where space is limited, and safety standards are stringent.

Additionally, organizing items by size allows for efficient use of storage space and facilitates easier access to the items when needed. Proper organization can prevent confusion and enhance logistics during operations on board the carrier.

Together, these actions contribute to a comprehensive approach to preparing dummy items for stowage, ensuring that all necessary precautions are taken to maintain safety and operational efficiency in the shipboard environment. Thus, it is accurate to state that all of the steps listed are in fact necessary for proper preparation.
