SECTION 1: DEFINITIONS & TERMINOLOGY (Questions 1-30)

1. What is the definition of a combustible liquid?

 A) A liquid with a flash point below 100°F
 B) A liquid with a flash point above 100°F
 C) A liquid with a flash point exactly at 100°F
 D) A liquid that ignites spontaneously

Answer: B. A combustible liquid is defined as having a flash point ABOVE 100°F,
distinguishing it from flammable liquids which have lower flash points .

2. What is the flash point of a liquid?

 A) The temperature at which a liquid ignites
 B) The minimum temperature at which a liquid gives off sufficient vapor to form an ignitable
mixture with air
 C) The temperature at which a liquid boils
 D) The temperature at which a liquid freezes

Answer: B. Flash point is the minimum temperature at which a liquid gives off sufficient
vapor to form an ignitable mixture with air near its surface .

3. What is the definition of "heat release rate" (HRR)?

, A) The temperature of a fire
 B) The energy being released by the individual fuels being consumed
 C) The speed at which a fire spreads
 D) The total heat produced by a fire

Answer: B. Heat release rate is the energy being released by the individual fuels being
consumed, measured in Watts or Kilowatts .

4. What is "flashover"?

 A) The ignition of a single fuel package
 B) A compartment fire transitioning from growth to fully developed phase where radiant heat
reaches ignition temperature of other combustibles
 C) The cooling phase of a fire
 D) The initial ignition of a fire

Answer: B. Flashover occurs in a compartment when radiant heat reaches the ignition
temperature of other combustible items within the room, producing fire gases .

5. What is the definition of "calcination"?

 A) The melting of glass
 B) The chemical and physical changes that occur in gypsum wallboard surfaces during a
fire
 C) The oxidation of metals
 D) The combustion of wood

Answer: B. Calcination refers to the chemical and physical changes that occur in gypsum
wallboard surfaces during a fire .

6. What is "crazing" in fire investigation?

 A) The melting of glass

, B) Complicated patterns in glass caused by rapid cooling or heating
 C) The charring of wood
 D) The calcination of gypsum

Answer: B. Crazing refers to complicated patterns in glass caused by rapid cooling or
heating .

7. What is the definition of "pyrolysis"?

 A) The combustion of materials in the presence of oxygen
 B) The thermal decomposition of materials without oxygen
 C) The cooling of materials
 D) The melting of materials

Answer: B. Pyrolysis is the thermal decomposition of materials in the absence of oxygen,
producing combustible gases .

8. What is "heat flux"?

 A) The total heat produced by a fire
 B) The measurement of the rate of heat transfer to a surface
 C) The temperature of a fire
 D) The speed of fire spread

Answer: B. Heat flux is the measurement of the rate of heat transfer to a surface, typically
measured in W/cm² .

9. What is the definition of "thermal inertia"?

 A) Heat x density x thermal conductivity
 B) The temperature of a material
 C) The speed of heat transfer
 D) The mass of a material

, Answer: A. Thermal inertia is the product of thermal conductivity, density, and specific heat
capacity (k × ρ × c) and is a key factor in considering a material's reaction to heating and
ease of ignition .

10. What is "exothermic" reaction?

 A) A reaction that absorbs energy
 B) A reaction that results in the release of energy in the form of heat
 C) A reaction that requires energy
 D) A reaction that produces no energy

Answer: B. An exothermic reaction results in the release of energy in the form of heat .

11. What is the definition of "combustion"?

 A) The melting of materials
 B) A chemical process of oxidation that occurs at a rate fast enough to produce heat and
usually light
 C) The cooling of materials
 D) The decomposition of materials

Answer: B. Combustion is a chemical process of oxidation that occurs at a rate fast enough
to produce heat and usually light in the form of either a glow or a flame .

12. What is "conduction" in fire investigation?

 A) Heat transfer through a solid material
 B) Heat transfer through a fluid
 C) Heat transfer through electromagnetic waves
 D) Heat transfer through a vacuum
