Abstract
Guidelines for both safe and low-risk stand-off distances in the vicinity of underwater detonations are stated in a set of tables called the 60-Series, which are published by the United States Naval Surface Warfare Center and are used operationally by Canadian Armed Forces divers. We propose a method to calculate stand-off distances which is in good agreement with the 60-Series tables for most values of charge weight, water depth, and swimmer depth. Using the same methodology, we propose new stand-off ranges for charge weights smaller than those currently included in the 60-Series publication (< 25 lb TNT), and we examine the effect of the charge’s depth on the stand-off ranges. We also discuss several limitations of the current guidelines.
