QD requirements set limits on the NEW of ammunition or explosive items that may be stored at one
location based on the characteristics of the items and the hazards that they present. QD requirements
also specify how near a storage location may be to buildings and other areas used by the local people,
and how near it may be to other ammunition or explosive storage sites.
To put it simply, QD requirements are intended to protect persons and property near storage areas.
They also minimize the possibility of an explosion in a given storage site causing an explosive chain
reaction in nearby storage sites.
The paragraphs that follow describe some of the QD terms and definitions you must become familiar
with. You should refer back to this section as you read the rest of this lesson to keep this information
fresh in your mind.
