Fire Behavior- Introduction to Fire Suppression

Summary

Summary

In order to understand the details of sprinkler protection, it is imperative that people working in the field have a basic understanding of some of the principles of fire science and behavior and how they affect suppression.

Fire is a complex reaction that is based in chemistry and follows the laws of physics. Thermodynamics is a big part of fire spread. To be able to suppress or control a fire may well require the knowledge of fire chemistry and the understanding of some basic laws of physics. The most basic of these laws is that mass absorbs energy. This principle, coupled with the fact that fire burns on surfaces, explains why some objects burn so readily.

Ignition can't take place unless the fuel is correct, the proper amount of air is present, and an energy source of sufficient size is available. Once these elements are in place, combustion begins, and a complex and ever-changing chemical chain reaction is sustained. To eliminate a fire requires the removal or reduction of one of the four elements. This can be done by cooling, smothering, or changing the chemical composition of the fire reaction. Different agents will affect one of these mechanisms to cause suppression.
