MM2600, Lesson 2
Lesson 2
FIRE SYMBOLS AND CHEMICAL HAZARD SYMBOLS
Task. This lesson is based on the following task from STP 9-55B12-SM: 093-400-1163, Identify Fire
Symbols and Chemical Hazard Markers for Ammunition.
Objective. When you have completed this lesson, you should be able to identify fire symbols and
chemical hazard symbols for an ammunition area.
Conditions. You will have this subcourse book and work without supervision.
Standard. You must score at least 70 on the end-of-subcourse examination that covers this lesson
and lesson 1.
IDENTIFYING FIRE SYMBOLS
A fire symbol is a symbol displayed in ammunition storage areas to provide a guide for fire-fighting
forces. Ammunition is divided into four fire divisions according to the danger created by the type of
ammunition involved in a fire. The divisions are identified by the numbers 1, 2, 3, and 4. Fire symbol 1
indicates the greatest hazard. The hazard decreases as the fire division number increases. As a fire
symbol, each number is displayed on a specially-shaped placard for better visibility at long distances.
See the chart on this page and figure 2-1.
Fire symbols are displayed on all buildings and at all outdoor storage sites. They are easily visible to
approaching fire-fighting forces while the forces are still at a safe distance.
When railroad cars and motor vehicles are loaded with ammunition and not destined for off-post
movement, they are considered temporary storage sites and must therefore display at least two fire
symbols. All fire symbols displayed must indicate the hazard according to the type of ammunition
stored in the location.
