Flashcards in Chapter 10 Deck (48):
When does size up begin
During pre planning and when driving around
Two types of size up
Should you always do a 360
Yes, unless you have a good exception
What should the size up include, for the building?
The general use and size classification
Basic construction, era, features
What is burning
The foreground clock
First clue of size up is
5 sub groups of occupancy for rapid street guide
Single Family dwelling. Institutional
Multi family dwelling. Public assembly
Main Street commercial. Misc building
For the Main Street commercial, you should probably announce what in size up?
The actual business type, strip mall, retail store, eatery
Manufacturing/warehouse by defn does not allow and can involve what?
The general public
Institutional includes what types of businesses?
Schools, jails, courts, hospitals,
Public assemblies can be what size and include?
Small to medium sized and include restaurants and churches
What are some buildings in the Misc category?
Utility substations, toll plazas
For the 360 size up, what will the good officer scan for?
Building construction considerations
Smoke and fire conditions
Status of building( are people there)
The initial size up includes a brief judgement on:
Obvious fire and smoke conditions
What's the best hand held light source for size up?
Flood style hand light, not pencil beam
Allows to see more features and refract off of smoke
Modern town homes are most likely from what era?
Dwellings with centrally located fireplaces are from what era?
Industrial and or historic
Dwellings with attached or adjoining garages with small doorways are from what era
Prior to Industrial
Commercial buildings with arched, bridge truss or sawtooth roofs are probably from what era?
Prior to post WWII-legacy
Unreinforced masonry is from what era?
Prior to pre WWII industrial
Exposed rafter tails of 2x4's are from:
Engineered LW era
Long Windows, rolling doors and pilasters mean:
Wide open interior and early collapse possible
4 building status classifications
How should you treat residential buildings for status?
As occupied unless reliable info proves otherwise
What can a large white X across a red background mean on a building?
Abandoned building that is too dangerous structurally for interior firefighting
What does one slash on a background mean?
The building might be sound, but interior ops should be limited to a quick search by permission from IC
Why should you always carry a pike pole?
To determine what is burning. Pull ceiling, take a look
What is burning?
Turn back time for lightweight and conventional exposed structural members
Lightweight- 5 minutes
Define foreground clock by the author's standards.
Once personnel are on scene, how long will it take to make a visible impact on the fire?
For his foreground clock, what 5 tasks are to be accomplished?
Exit and PPE
Conduct a 360
Move water and get it to the fire
3 factors that will work against you at a fire.
The fire is weakening the building
Water weighs 8.35 lb per gallon
National average for collapse of lightweight wood trusses?
How does a building on fire affect the fire ground clock if it was burning when you pulled up?
Add that to the known fireground implementation clock
6 tactical challenges for buildings
3 factors that determine fire spread
Internal geometry of the building
The fire load
The heat and intake (flow path)
2 odd signs of collapse:
Doors out of plumb
Water flowing out of the building that doesn't match amt going in
Collapse is an algorithm of :
Forcible entry is a two part operation that consists of:
Forcible entry and forcible exit
In regard to Search as a tactical challenge, what has changed?
Society changed the fire (high heat, explosive gases) and society changed the building (LW and air tight)
How long can a person survive in 300 degrees?
What do heat cracked Windows and high velocity smoke indicate?
A non survivable room
8 specific hazards that effect tactics:
Storage of Hazardous materials
Multiple overhead lines
Previous fire and collapse
Multiple entry levels or sloping grade
3 primary hazards of Facades
Common attic on the exterior and may be to the attic
They can collapse over an entry or exit
What are the game changing hazards?
Base of operations
Who has the role to triage and predict collapse on a fire?
The person assigned to continually read the building (IC or Safety)
Triage can set the stage for predicting what?
And general collapse
What are the two questions asked in Joe's Triage BS?
When not to enter a Bldg
When to get out
