Ch 17 Fire Attack by kc Flashcards
4 levels of fire behavior in a structure
- Ignition 2. growth 3.fully developed 4. decay
The volume between inlet and exhaust. Moves from higher pressure to lower pressure areas. i.e. doors/windows/openings etc.
Flow Path
Name the 4 factors that distinguish modern from legacy dwellings.
- Larger homes 2. Open house geometry 3. Increased fuel load 4. New construction material
Its a basic tactical unit for emergency operations, with a fire officer in the role of a working officer in the role of a working supervisor.
A fire company
What are Lloyd Laymans 5 steps in the Size-up process?
FPSDP 1. Facts 2. Probabilities 3. Situation 4. Decision 5. Plan of operation
This plan is updated throughout the incident and reflects incident strategy & tactics and risk management.
I. A. P. (incident action plan)
1 in Lloyd layman’s 5 step process. Things that are known about the incident are
Facts
2 in Lloyd layman’s 5 step process. Things that are likely to happen or can be anticipated based on known facts.
Probabilities
3 in Lloyd layman’s 5 step process. This Size-up step has 3 considerations 1. resources on scene are insufficient 2. resources, on scene capabilities and Limititations in relation to the problem 3. resources on scene capabilities & limitations of personnel training and experience.
Situation
4 in Lloyd layman’s 5 step process. Requires specific judgement based on known facts & probabilities & situation evaluation.
Decision
5 in Lloyd layman’s 5 step process. Last step used to mitigate the incident.
Plan of Operation
What is Lloyd Layman’s
5 Step process?
- Facts
- Probabilities
- Situation
- Decision
- Plan of operation
Firfighters advance into buildings w/hose lines to extinguish & over power the fire.
Offensive Operstaion
When risks outweigh benefits, Firefighters not allowed in the structure
Defensive Operation
In the NFA’s Size-up process this phase considers what you know before the incident occurs
Pre-incident information
In the NFA’s Size-up process this phase begins on receipt of an alarm. Conditions present at the incident, 360 degree walk around
Phase 2:
Initial size up
- what do i have?
- where is it going?
- how do I control it?
In the NFA’s Size-up process:
This phase continuously evolves, evaluation of effectiveness of plan executed. Requires a constant flow of feedback.
Phase 3:
Ongoing size up
Its a key factor of size up when selecting the strategic mode. It dictates the degree of risk acceptable in a situation.
