Lesson 8: Fire Hazards
Embedded Files
Fire hazards refer to situations or conditions that can cause or contribute to the outbreak, spread, or severity of a fire. Fires can have significant impacts on human life, property, and the environment.
Fires can be prevented by following proper safety procedures, such as keeping flammable materials away from heat sources, not overloading electrical circuits, and maintaining fire safety equipment like smoke detectors and fire extinguishers.
THE ELEMENTS OF THE FIRE TRIANGLE
THE ELEMENTS OF THE FIRE TRIANGLE
The Fire Triangle model is useful for understanding the basic principles of fire behavior and for developing strategies to prevent and extinguish fires. By removing any one of the three elements, a fire can be prevented or extinguished. For example, by removing the fuel source, the fire will be starved of the energy it needs to continue. Similarly, by removing the heat source or limiting the oxygen supply, the fire can be extinguished.
Fuel is any material that can burn and provide energy to the fire. It can be solid, liquid, or gas, and it can come from a variety of sources such as wood, paper, gasoline, or natural gas. The amount, type, and arrangement of fuel can affect the intensity and duration of the fire.
Oxygen is a gas that is necessary for a fire to start and continue. It reacts with the fuel, creating heat and flame. The amount of oxygen present in the air affects the rate at which the fire burns. If there is not enough oxygen, the fire will suffocate and extinguish.
Heat is the energy required to raise the temperature of the fuel to the point where it will ignite. It can come from a variety of sources such as an open flame, a spark, friction, or even sunlight. The temperature, duration, and intensity of the heat source can affect the size and behavior of the fire.
