Heat Transfer & Stages of Fire

What are the three methods of heat transfer mentioned in the text?

• Conduction, Convection, Radiation

• Evaporation, Condensation, Sublimation

• Reflection, Refraction, Diffraction

• Compression, Rarefaction, Absorption

Which stage of a fire is characterized by the fire quickly spreading to all remaining combustibles in the space?

• Growth Stage

• Fully Developed Stage

• Flash Over Stage

• Decay Stage

What is the definition of Convection as mentioned in the text?

• Transfer of heat through the motion of smoke and hot gases in the air

• Transfer of heat through electromagnetic waves

• Transfer of heat from a source across an intervening space

• Transfer of heat through a solid object

What is the way to prevent heat transfer through Radiation as mentioned in the text?

• Increase the oxygen supply

• Cool deck or bulkhead

• Extinguish the heat source

• Secure the ventilation

What gases are given off by a fire as mentioned in the text?

• Hydrogen and Helium

• Carbon Dioxide and Carbon Monoxide

• Argon and Neon

• Oxygen and Nitrogen

What is the Flash Over Stage of a fire characterized by?

• Fire consuming all available oxygen and fuel

• Fire quickly spreading to all remaining combustibles

• Fire localized in the vicinity of its origin

• Fire transitioning to smoldering stage

What is an example of heat transfer by Conduction?

• Heat is conducted through the water.

• Heat is conducted through a bulkhead or deck and ignites combustibles on the other side.

• Heat is conducted through the air.

• Heat is conducted through the air vents.
