Prior to 1967 the “front” sector of an Earth-Covered Magazines (ECM) was measured from the center of the headwall. Magazines were constructed based on this assumption.
Now, the front exposure arc originates inside the magazine, intersecting at the Headwall & sidewall (the arc is widened). Now the canted magazines have a Side to Front exposure by a thin margin.
This increases the inter-magazine (IMD) distance required, increases the required K factor, thus requiring drastically reduced storage limits in some cases.
What are your thoughts?
If you are hunting for an immediate solution, I believe you have two options. The first option is to reduce the net explosive weight limit in the magazine, which is the most correct. The second option is to submit a deviation with the site plan. Often times, the magazine will cube out before the sited net explosive weight is achieved.
