Ch. 17: Fire Attack Flashcards
What is described as the volume between an inlet and an exhaust that allows the movement of heat and smoke from a higher-pressure area within the fire area toward lower-pressure areas accessible via doors, windows, and other openings?
flow path
What is the only way to go from a ventilation-limited to a fuel-limited fire?
Through the application of water before vertical ventilation.
What is an important factor in limiting heat release and temperatures in the house?
Limiting flow paths until fire suppression water is ready to be applied.
What means that, without ventilation, fire would consume all of the fuel?
fuel limited
What is a systematic process of gathering and processing information to evaluate the situation and then translating that information into a plan to deal with the situation?
size-up
What is Layman’s five-step process for analyzing emergency situations?
[FPSDP]
- Facts
- Probabilities
- Situation
- Decision
- Plan of operation
What are the things that are known about the situation?
facts
What are the things that are likely to happen or can be anticipated based on the known facts?
probabilities
What are the three considerations involved in the situation assessment?
- Whether the resources on scene and en route will be sufficient to handle the incident.
- The specific capabilities and limitations of the responding resources in relation to the problem.
- The capabilities and limitations of the personnel, based on training and experience.
What step in Layman’s process requires the fire officer to make specific judgment decisions based on the known facts and probabilities, as well as the situation evaluation?
decision
What is the National Fire Academy’s (NFA) size-up system that includes three phases?
[PIO]
- Preincident information
- Initial size-up
- Ongoing size-up
What is a key factor to size-up when selecting the appropriate strategic mode?
risk-benefit analysis
What consists of an advance into the fire building by firefighters with hose lines or other extinguishing agents to overpower the fire?
offensive operation
What is used when the risks outweigh the expected benefits?
defensive operation
What strategy can be used when the recognition that the situation could change to an offensive approach when interior conditions improve?
transitional operation
