LESSON 2
Figure 2-9 (cont). Fire Symbols and Chemical Hazard Markers
NOTE
You may see before the class and division a number in parentheses such as (18) 1.1, (12)
1.2, (08) 1.2 and so on. This number is the MINIMUM DISTANCE (X 100 FEET) TO
PROTECT AGAINST FLYING FRAGMENTS.
Since fragments are the main concern when using these minimum distance factors you will find
most of the numbers in parentheses before items in 1.2, "Nonmass detonating, fragment producing."
To simplify this information let's look at a few examples.
When you see (04) 1.2 after an item of ammunition, it means the minimum distance to protect
against fragments (or other specified hazards) is 400 feet. The item is in class and division 1.2. When
you see (08) 1.2 it means 800 feet minimum distance, (12) 1.2 is 1,200 feet and so on.
