Basic of Fire & Fire Triangle Concept

Which of the following is NOT one of the three essential elements required for a fire to occur according to the Fire Triangle concept?

• Fuel

• Oxygen

• Heat

• Water

Refer to the diagram of the Fire Triangle, which shows three sides labeled Heat, Oxygen, and Fuel, with Chemical Reaction at the center. If one side of the triangle is removed, what will happen to the fire?

• The fire will continue to burn as long as the other two elements are present.

• The fire will extinguish because all three elements are necessary.

• The fire will become stronger due to the chemical reaction.

• The fire will change color but not go out.

Refer to the diagram showing the Fire Triangle. Which of the following is NOT one of the three essential elements required for a fire to occur according to the Fire Triangle model? A) Oxygen source B) Heat source C) Water source D) Fuel The diagram illustrates the Fire Triangle, which includes oxygen source, heat source, and fuel as the three essential elements for combustion.

• Oxygen source

• Heat source

• Water source

• Fuel

According to the Fire Triangle Model, which action would extinguish a fire by eliminating the oxygen required for combustion? A) Switching off the gas supply B) Covering the fire with a wet blanket C) Keeping gases below ignition temperature D) Increasing the heat source The Fire Triangle Model explains that covering a fire with a wet blanket eliminates oxygen, thereby extinguishing the fire.

• Switching off the gas supply

• Covering the fire with a wet blanket

• Keeping gases below ignition temperature

• Increasing the heat source

Which class of fire involves combustible liquids such as petroleum oil, gasoline, and paint, but does not include fires involving cooking oil and grease?

• Class B

• Class F

• Class A

• Class D

Based on the table showing types of fire extinguishers and the classes of fire they are suitable for, which type of fire extinguisher is specifically recommended for Class D fires?

• Special dry powder

• Water and foam

• Carbon dioxide

• Wet chemical

Which of the following is the first step in developing a fire safety plan?

• Develop a statement of intent

• Assess all fire hazards such as material, procedures, and building design

• Develop a fire safety task force committee

• Implement fire prevention practices

A company is reviewing its fire safety plan. They have identified that their building contains cardboard, foam composition, and paper, and uses heating, ventilation, and air conditioning systems, as well as electrical equipment with wiring and extension cords. Based on this information, which areas should the company focus on when assessing fire hazards?

• Materials and building design

• Only the emergency exits

• Employee training programs

• Company financial records

Which of the following is an example of hot work that requires proper control procedures for fire hazard control?

• Welding

• Storing flammable material

• Housekeeping

• Inspection

Which type of fire extinguisher is typically used for electrical fires? Refer to the image showing different types of fire extinguishers, including water, foam, carbon dioxide, halon, and powder types.

• Carbon dioxide extinguisher

• Water extinguisher with added chemicals for electrical fires

• Foam extinguisher for electrical fires

• Powder extinguisher with water
