Hikal Fire Officer Interview Questions and Answers

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 b...read more

Fires are classified based on the type of fuel involved, such as Class A, B, C, D, and K fires.

• Class A fires involve ordinary combustibles like wood and paper

• Class B fires involve flammable liquids like gasoline and oil

• Class C fires involve energized electrical equipment

• Class D fires involve combustible metals like magnesium and titanium

• Class K fires involve cooking oils and fats

Types of classification include hierarchical, binary, and multi-class.

• Hierarchical classification involves organizing categories into a tree-like structure.

• Binary classification involves categorizing data into two classes.

• Multi-class classification involves categorizing data into more than two classes.

Fires are classified into different classes based on the materials involved and the appropriate extinguishing methods.

• Class A: Ordinary combustibles (wood, paper, cloth) - Extinguished with water.

• Class B: Flammable liquids (gasoline, oil) - Extinguished with foam or dry chemicals.

• Class C: Electrical fires - Use non-conductive extinguishing agents like CO2.

• Class D: Combustible metals (magnesium, sodium) - Requires speci...read more

Types of extinguishers include water, foam, CO2, dry powder, and wet chemical.

• Water extinguishers are suitable for Class A fires involving solid materials like wood or paper.

• Foam extinguishers are effective on Class A and B fires, involving flammable liquids.

• CO2 extinguishers are used for electrical fires (Class C) and flammable liquids (Class B).

• Dry powder extinguishers are versatile and can be used on Class A, B, and...read more

A tetrahedron is a polyhedron with four triangular faces, six straight edges, and four vertex corners.

• A tetrahedron is a three-dimensional shape.

• It is made up of four equilateral triangles.

• It has a total of six edges and four vertices.

• Examples of tetrahedrons include pyramids and certain molecular structures.
