Understanding Fire and Fire Extinguishing Equipment

What is Fire?

Fire is a rapid oxidation process that results in the release of heat and light. It is a chemical reaction that occurs when three essential components come together: heat, fuel, and oxygen. This combination is often referred to as the "fire triangle." Removing any one of these components can prevent or extinguish a fire.

1. Heat: This is the energy source that raises the material to its ignition temperature. Common sources include electrical faults, open flames, and friction.

2. Fuel: This is the combustible material that burns, such as wood, paper, fabric, or gasoline.

3. Oxygen: Fire requires oxygen to sustain combustion. It is generally supplied by the air around us.

The process of combustion can be broken down into four stages:
- Ignition: The initial stage where the heat source brings the fuel to its ignition point.
