Q

According to IFSTA’s Structural Firefighting: Initial Response Strategy and Tactics; the compartment surrounding the burning fuel plays an important role in fire development, impacting available ventilation, access to additional fuel, and heat losses and gains. Compartment fire development depends upon whether the fire is fuel-limited or ventilation-limited. What definition is correct regarding fuel-limited fires?

A

A) Rapid transition form the growth stage to the fully developed Stage

B) When sufficient oxygen is available for flaming combustion. The fuel’s characteristics, such as heat release rate (HRR) and configuration, control the fire’s development

Q

According to IFSTA’s Structural Firefighting: High-Rise Fire Firefighting, products of combustion travel upward toward the top of a building. If fire does not generate enough heat to cause the smoke to rise to the top of the building, the temperature of the smoke will eventually equal that of the surrounding air. When this equalization of temperature occurs, the smoke losses its buoyancy, ceases to rise, and form layers of smoke within the building. This is know as?

A

A) Stack effect

B) Statification

C) Heat intensity and compartmentation

D) Ceiling jets, or mushrooming
