To identify these hazards for fire-fighting operations, fire symbols and chemical hazard markers as
shown in Figure 2-23 and Figure 2-24 are used.

TM 9-1300-206 contains tables showing the items in each QD class/division. To determine the QD
class/division of an ammunition or explosive item, you can use Table 5-21 in TM 9-1300-206. An
extract of this table is shown in Figure 2-13 on page 2-10.
A number in parentheses before the class and division, such as (18) 1.1, (12) 1.2, or (08) 1.2, gives the
minimum distance in feet (times 100) required to protect against flying fragments. Most of these
numbers in parentheses are found before items in class/division 1.2 (non-mass-detonating, fragment-
producing). The following examples illustrate what these numbers mean.
When you see "(04) 1.2" after an item of ammunition, it means that the minimum distance to protect
against fragments (or other specified hazards) is 400 feet. This item is in class 1, division 2. When you
see "(08) 1.2," it means that an 800-foot minimum distance is required. A class/division of "(12) 1.2"
means that a distance of at least 1,200 feet is required, and so on.
