3rd Edition Chapter 17 - Fire Attack Flashcards
Single-family dwellings constructed since 1980?
Modern Dwellings
Single-family dwellings constructed before 1980?
Legacy Dwellings
What are the four factors that distinguish modern dwellings from legacy dwellings?
- Larger homes
- Open house geometries
- Increased fuel loads
- New construction materials
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
Observations at the Governor’s Island experiments included the following points when combatting ventilation-limited compartment fires?
- It is essential to control the access door to restrict introduction of air into the fire room and thereby delay flashover
- The only way to go from a ventilation-limited to a fuel-limited fire is through application of water before vertical ventilation
- “Softening” the target by applying 30-90 seconds of water into the compartment dramatically reduces fire development and improves conditions
- You cannot make a big enough ventilation hole to localize fire growth or reduce temperatures in ventilation-limited structure fires
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 end result of a good size-up? It considers all the pertinent information, defines strategies and tactics, and assigns resources to complete those tactics
Incident Action Plan
What is one of the most significant factors in size-up?
Visualization
What’s the Lloyd Layman’s five-step process for analyzing emergency situations?
- Facts
- Probabilities
- Situations
- Decision
- Plan of Operation
The things that are known about the situation?
Facts
Things that are likely to happen or can be anticipated based on the known facts?
Probabilities
The situation assessment involves three considerations?
- Whether the resources on scene and en route will be sufficient to handle the incident?
- Specific capabilities and limitations of the responding resources in relation to the problem
- Capabilities and limitations of the personnel, based on training and experience
This step of Layman’s size-up requires the fire officer to make specific judgement based on the known facts and probabilities, as well as the situation evaluation?
Decision
In Decision phase of Layman’s size-up, the officer needs to answer four questions?
- Are there enough resources responding to and on the scene to extinguish the fire or mitigate the situation?
- Are sufficient resources available, and do conditions allow for an interior attack?
- What is the most effective assignment of on-scene resources?
- What is the most effective assignment of responding resources?
What are the three phases of the National Fire Academy’s size-up process?
- Pre-Incident Information
- Initial Size-Up
- Ongoing Size-Up
Which phase of the NFA’s size-up process considers what you know before the incident occurs? Closely mirrors the Facts step identified by Layman
Phase 1: Pre-Incident Information
