Quantity-Distance (QD) is an established method used among other things for safety related to ammunition storage. The beauty of the QD-method is obvious - the simplicity - a simple solution to a complicated problem.

As often is the case, the simple solution may be too simple for some applications. This makes a need to question the QD-method - if, when and how to use it.

QD methods are generally appreciated by authorities who have to apply it and they consider it easy to understand (Acceptable - Not acceptable and nothing in between). Technical people who are involved in the ammunition safety process are well aware of the deficiencies associated with it. These deficiencies have led to alternate ways to be used in safety regulations e.g. methods based upon risk analysis.

Increased costs for land and military operational requirements make it necessary both to apply alternate methods to ensure adequate safety and to question the criteria behind the QD: s and how they are used for different situations.

The paper describes the background to and the development of some current regulations for the storage of ammunition. Comparisons are made of different criteria used and how these criteria influence on QD: s and Field Distances for the Military Operational Theater.

The paper gives special emphasis on work done within the NATO AC/326 Operational Safety Group and efforts made to reduce Field Distances in the interest of Operational Readiness.
