A. Introduction
OUTLINE SHEET 1-15-1
CHEMISTRY AND CLASSES OF FIRES
This lesson discusses fire chemistry--the study of flammable materials and
how they ignite. The knowledge gained in the lesson could save your life.
B. Enabling Objective(s):
16.8 Identify the elements of the fire triangle and fire tetrahedron.
16.9 Explain the principle of the fire triangle and fire tetrahedron as
applied to extinguishing a fire.
16.10 Identify the characteristics of the four classes of fire and the
agents used to extinguish them.
16.11 Identify procedures to prevent fire and for firefighting readiness.
22.6 Explain the relationship between teamwork and procedures to prevent
fire.
23.15 Explain the relationship between the Navy Core Values and chemistry
and classes of fire.
C. Topic Outline
1. Introduction
2. Elements of the Fire Triangle and Fire Tetrahedron
a. Fire triangle
(1) The following requirements must exist for fire to occur:
(a) ____________--From the air in the earth’s atmosphere.
(b) Fuel--Any substance that will ____________.
(c) ____________--At a high enough temperature to cause
fuel to burn.
(2) However, the fire triangle does not completely describe
that process that causes fuel to burn. There is a fourth
requirement--a ____________ ____________ ____________.
b. Fire tetrahedron--A chemical chain reaction between oxygen, fuel,
and heat must occur to have a fire.
3. Extinguishing a Fire Using the Principles of the Fire
Triangle/Tetrahedron
a. General principle of firefighting--The removal of any one of the
elements of a fire triangle/tetrahedron will extinguish the fire.
