(respectively) net explosive weight to be stowed. For
example, if you are stowing Class 1 Division 1
explosives with a net explosive weight of 13,000
pounds, you find the minimum net explosive weight in
Col 1 (10,000 pounds) and the maximum net explosive
weight in Col 2 (15,000 pounds); then, read horizontally
across the page to obtain the distance requirements.
Columns 3, 4, and 5 list the minimum distance, in feet,
from the storage site (in this case a standard
earth-covered magazine) to an inhabited building. If the
net explosive weight is 13,000 pounds, the minimum
distance from the front or side of the magazine to the
closest inhabited building is 865 feet (Col 3). The
minimum distance from the rear of the magazine to an
inhabited building is 615 feet (Col 4). The minimum
distance from the magazine to other potential explosive
sites (PES) is 900 feet. Columns 6, 7, and 8 list the
minimum distance, in feet, from the magazine to public
traffic routes. It is read in the same manner as Columns
3, 4, and 5.
The Q-D hazard requirements do not apply to
ammunition and explosives while in transit.
Ammunition and explosives in transit are regulated by
the Department of Transportation (DOT). The Q-D
hazard classifications do not necessarily mean that all
ammunition and explosives within a classification can
be stowed in the same magazine. All ammunition and
explosives listed as Class 1, Division 1 explosives may
not be compatible when stowed together. For example,
assembled HE rockets and GP bombs are classified as
Class 1, Division 1 explosives, but they aren’t
