LESSON
MAGAZINE STORAGE AREA QUANTITY-DISTANCE AND COMPATIBILITY
MQS II Critical Task: 03-4010.01-0002
OVERVIEW
LESSON DESCRIPTION:
In this lesson you will learn to determine the QD requirements and storage compatibility for Class V items to be
stored in the Magazine Storage Area.
TERMINAL LEARNING OBJECTIVE:
ACTION:
Determine MSA quantity-distance and compatibility requirements.
CONDITION:
With the information provided, you will be required to determine the QD and compatibility of
selected ammunition and explosive items.
STANDARD:
To demonstrate competency of this task, you must achieve a minimum of 70% on the
subcourse examination.
REFERENCES:
The material contained in this lesson was derived from the following publications: AMC-R
385-100 and TM 9-1300-206.
INTRODUCTION
As a conventional ammunition management officer, you are responsible for the safe and efficient storage of
ammunition and explosive materials at US Army and/or Department of Defense (DOD) ammunition storage
facilities in the United States and overseas. To accomplish this mission, you must have a thorough understanding
of the magazine storage area (MSA) quantity-distance (QD) and storage compatibility requirements.
Each type of munitions item stored at US Army/DOD activities is assigned to an appropriate storage compatibility
group (SCG) and a quantity-distance (QD) hazard class/division. The factors that determine ammunition and
explosives SCGs and hazard classes are evaluated based on technical data obtained from ammunition drawings,
net explosive weight (NEW), and from testing during the research, development, testing and evaluation (RDTE) of
these items.
Safety Considerations. As always, safety is a major function of the conventional ammunition management officer.
Safety will be discussed throughout this subcourse, because in the magazine storage area, quantity-distance and
storage compatibility mean safety.
Quantity-Distance (QD). The QD requirements were developed to protect nearby communities, inhabited
buildings, public roadways, railroads, and other facilities from the effects of explosions that might occur within a
magazine storage area (MSA). When using the term quantity-distance, we are talking about the net explosive
weight (NEW) of ammunition and/or explosive items that might be stored at one location. QD is based on the
characteristics of given munitions and the hazards they present. QD also includes the minimum distance these
facilities must be separated both from buildings and areas used by the local population, and from other
ammunition/explosive sites.
