Now let's work a class 1.4 problem. We have 5.56mm ball small arms ammunition to store and we
want to find the IBD. First check table 5-21 (fig. 2-31) to verify the class and division. Then go to table
5-17 (fig. 2-32). There is no limit on the amount of NEW, simply read across the table to the "Inhabited
building" column. The IBD is 100 feet.

There are no quantity-distance tables for class 6.1 items because they are not explosive hazards.
Class 6.1 is chemical group A and some chemical group B items. These chemical groups are not to be

The quantity-distance requirements for chemical agents with explosive components are as specified

components as quantity-distance class 6.1. But chemical ammunition group A with explosive
