When multiple types of ammunition are stowed in a magazine, what must be posted?

When multiple types of ammunition are stowed in a magazine, it is essential to post a stowage chart. This chart provides critical information about the correct placement of various ammunition types to ensure safety and compatibility within the storage facility. By clearly indicating where different types of ammunition should be stored, the stowage chart helps to prevent accidental mixing of incompatible rounds that could lead to dangerous reactions, such as fires or explosions.

The stowage chart also assists personnel in maintaining proper inventory control and enhances overall safety within the magazine. It serves as a reference for loading and unloading procedures, reducing the likelihood of errors during these operations by providing visual guidance.

In this context, while a warning sign might alert staff to hazards, and an inventory list serves to track what is present, it is the stowage chart that directly addresses the specific requirement of managing multiple types of ammunition together safely. A compatibility chart could provide helpful information but is not typically required to be posted in every magazine setting. Thus, the stowage chart is the most relevant and essential document to have visible.
