Manage the Risk of Radiant Energy

摘要

Fire is a complex phenom-enon that requires advanced degrees in chemistry, physics, and engineering to fully understand. Nevertheless, it is important for all firefighters not only to understand the basic principles of fire and heat transfer but also to be reminded periodically of how these principles relate to their line-of-duty responsibilities and their personal safety. Fires result when fuel, oxygen, and heat come together. When ignition occurs and combustion begins, heat is generated. Smoke, flame, and the release of gases are also products of combustion and are the physical signs that a potentially deadly situation is at hand.
