CODE BASICS

Fire, Based on the 2009 International Fire Code

(The information below is excerpted from the 2009 Building Code Basics series.)

Combustible dust-producing operations occur in a variety of industries, including food production, manufacturing of pharmaceuticals, certain wood working operations, and some plastic manufacturing processes. IFC Chapter 13 addresses the prevention of dust explosions, which technically are dust deflagrations. A deflagration is an exothermic reaction (meaning it releases heat) resulting from a rapid oxidation of a combustible dust, in which the reaction progresses through the unburned material at a rate less than the velocity of sound. Deflagrations are commonly termed as "slow explosions." Deflagrations are far more common than explosions, which have burning rates greater than the speed of sound.

The Building Code Basics series explains requirements using non-code language.
