Computer Enhancements for Determining Explosive Fragmentation Q-D
Abstract
Operations involving the manufacture, storage and maintenance of explosives and munitions create an unusual risk to people and unrelated facilities. To reduce this risk to acceptable levels Department of Defense Explosive Safety Regulations define minimum separation distances. Required safety zones are based on a 670 foot separation distance for quantities of explosive less than 100 pounds and 1250 feet minimum for higher quantities. The land encumbered by these safety zones restricts flexibility in the effective use of total installation assets. In many cases the arbitrary separation distances required by regulation are overly conservative. The Department of Defense Explosives Safety Board (DDESB) has recently approved the use of specific fragmentation/debris prediction analyses procedures that can be used to reduce the required safety zones. These analyses procedures are available in a computer model named DISPRE. This paper discusses the prediction model and provides examples of how default driven explosive quantity safety zones can be substantially reduced. A preprocessor called DISPRE1 which greatly enhances the usefulness of the DISPRE code is also demonstrated.
