Hikal Fire Officer Interview Questions and Answers

Fire elements refer to the components necessary for a fire to occur, including fuel, heat, oxygen, and a chemical chain reaction.

• Fuel: Any material that can burn, such as wood, paper, or gasoline.

• Heat: The energy needed to raise the temperature of the fuel to its ignition point.

• Oxygen: The presence of oxygen in the air allows the fire to burn.

• Chemical chain reaction: The process by which the fuel is broken down and releases energy in the form of heat and light.

The fire Tetrahedron is a model that illustrates the four elements necessary for a fire to occur: fuel, heat, oxygen, and a chemical chain reaction.

• Fuel: any material that can burn, such as wood, paper, or gasoline

• Heat: the energy needed to raise the temperature of the fuel to its ignition point

• Oxygen: the presence of oxygen in the air that supports combustion

• Chemical chain reaction: a process where the heat produced by the fire sustains the reaction and allows it to continue
