What Is Fire?
Fire is a natural reaction between fuels, usually solids, and air. During combustion, fuels become hot enough to release molecules that contain oxygen. As a result, gases are formed. Once the fuel reaches this temperature, these molecules break apart, rejoining with oxygen from the air to produce new molecules. These new molecules are water molecules (H2O), carbon dioxide molecules, and other products, such as smoke. Other products may also result from incomplete burning.
Fire is a visible reaction of combustible fuel with oxygen. The reaction produces heat and light, which are the main components of a flame. Fires start by containing the three elements of oxygen, heat, and fuel. These three ingredients, known as the fire triangle, can be either slow or fast. Ultimately, it is the reaction of these three components that creates the flame. Whether a fire is fast or slow, the flame will appear as the fuel reacts with oxygen.
Fire starts in the oxygen-filled atmosphere and grows as more surfaces get hotter. The initial flame ignites more surfaces and the plume reaches the ceiling. As hot gases travel to the ceiling, they transfer heat and allow all fuels to reach ignition temperature at the same time. At this point, the fire has consumed most of the fuel and oxygen. This process is known as decay or burnout. The fire’s intensity begins to wane and oxygen is depleted.
Fire can provide mechanical work when the fuel is burned. The combustion process releases energy that can be used to move machinery. Wood was the primary fuel in prehistoric times and is still used today in some forms. In fact, the vast majority of the world’s electricity comes from fossil fuels. When these fuels are burned, they produce steam, which spins turbines and electricity. The combustion of these fuels allows a much higher diversity of species to exist.
A resource management plan defines the type of fire to be used. A resource management plan (RMP) describes the risk associated with a fire in a particular area and for a specific benefit. A resource order is a document that specifies the types of firefighting resources that are required to contain the blaze. A fuel break may consist of a natural barrier or a mechanically constructed line. A control line contains treated fire edges to prevent flare-ups from within the perimeter.
Modern applications for fire range from internal combustion vehicles to the production of electricity. Thermal power stations use fuels to ignite and create steam that drives turbines. These power plants provide electricity to a vast proportion of the world’s population. The heat and energy generated during the combustion process is also responsible for the colour of the flame. There are also countless ways to use fire in a different way. And that’s just the tip of the iceberg.
UA Little Rock follows State Fire Marshal Office requirements for fire safety and upgrades its fire alarm and suppression systems when constructing new buildings. During a fire, do not delay in getting to safety and reporting missing neighbors. If the fire has reached a building where you live, do not waste time collecting items. The best way to get out of a burning building is to stay low to the ground. In addition to staying low to the ground, avoid using elevators when possible.
