Fire and Electrical Safety Basics of fire chemistry and fire triangle Fire Chemistry Basics: Fire is a chemical reaction that occurs when three key elements are present in a specific combination. These elements interact to produce heat, light, and other byproducts like smoke and gases. The primary chemical reaction behind a fire is combustion, which involves a material reacting with oxygen from the air to release energy in the form of heat and light. The key components that need to be present for combustion are: Fuel : This is the material that will burn. Fuels can be solid, liquid, or gas and include wood, gasoline, oil, paper, etc. Oxygen : Oxygen is needed to sustain the combustion reaction. It is typically supplied by the surrounding air. Heat : Heat is necessary to raise the fuel to its ignition temperature, which is the point at which combustion can begin. When these three components—fuel, oxygen, and heat—are combined in the right proportions, a fire will occur. If any of these components is removed or altered, the fire will be extinguished. The Fire Triangle: The Fire Triangle is a simple model used to understand the essential elements required for fire to occur. It
