INSPECTING PROPELLING CHARGES
AND THEIR CONTAINERS
In this lesson, you will learn how to inspect artillery ammunition propelling charges and their containers. This
inspection will include air-testing propelling charge containers. There are many types of propelling charges, but
the M4 prop charge is the example used in this lesson. The M4 propelling charge is packed one to a container,
which means that 20 containers and 20 propelling charges must be sampled for an inspection (see the table on
For your inspection, choose a time when low humidity is expected. Moisture of any kind can affect the igniter and
the propellants of prop charges. If you must inspect prop charges during a period of high humidity, keep their
exposure to a minimum.
Have the samples transported from the storage area to the inspection area. Make sure the correct fire symbol is
posted before storage personnel off-load the samples. The correct fire symbol for prop charges is Fire Symbol 3.
In an actual inspection, all defects and other necessary information would be entered on an ASIR.
