Question: What are the exact sequential steps an officer must execute during a fire
emergency?
Answer: ✔✔
1. Activate the closest emergency fire alarm system.
2. Immediately contact Main Control to report your identity, the precise
location of the incident, the specific class of fire, and remain on the line until
the information is verified.
Question: What three fundamental components must interact simultaneously to
create a fire?
Answer: ✔✔ Fuel, heat, and oxygen.
Question: What unique element transforms the standard fire triangle model into a
Fire Tetrahedron?
Answer: ✔✔ The inclusion of an uninhibited chemical chain reaction alongside
fuel, oxygen, and heat.
Question: How is a "Chemical Chain Reaction" explained within the context of
combustion?
Answer: ✔✔ It is the self-sustaining combustion process where extreme heat
vaporizes fuel compounds, causing them to bond with surrounding oxygen
molecules, which generates intense additional heat that continually frees more fuel
elements.
Question: Which gaseous element is essential for sustaining both human life and
active combustion?
Answer: ✔✔ Oxygen.
, Question: What is the typical concentration of oxygen found in normal, breathable
atmospheric air?
Answer: ✔✔ A level of 21%.
Question: What is the absolute baseline concentration of oxygen required to
sustain human respiration and keep a fire burning?
Answer: ✔✔ A minimum threshold of 16%.
What percentage of oxygen causes the visual flame to go out? -ANSWER ✔✔15%
5% of oxygen does what do a fire? -ANSWER ✔✔Causes it to go out.
What are the three physical states of fuel? -ANSWER ✔✔Solid, Liquid, and Gases
What are the four classes of fire? -ANSWER ✔✔Class A: Ordinary Combustibles
Class B: Liquids
Class C: Energized Electrical
Class D: Metals
What are the four sources of heat energy? -ANSWER ✔✔1: Chemical
2: Electrical
3: Mechanical
4: Nuclear
What are the three types of heat transfers? -ANSWER ✔✔1: Conduction
2: Convection
