Engine Company Ops Manual Flashcards
Whenever possible avoid a layout that places “______” in the route of travel.
Handlines
The Space between both handrails in a stairwell is called?
A Well-Hole
What does the Fire Tetrahedron consist of?
Oxygen,Heat,Fuel, Chain Reaction
What are the 4 stages of fire growth? And, explain them?
- Incipient Stage (Heat,oxygen, and fuel source combine to form a chemical reaction.
- Growth Stage (Fire increases in size from small flames to full fire)
- Fully-Developed Stage (Entire room and contents are on fire)
- Decay Stage- All available oxygen is consumed.
Warning signs of backdraft?
- Heavy dense smoke with no flames seen
- Black smoke pushing around closed doors
- Glass stained with smoke condensation and pulsating,
- Smoke being pulled back into a building.
What is Hydralic Ventilation & how is it achieved?
Using a Fog pattern to remove smoke from a compartment or building via a opening.
Place nozzle 2 feet away into a fog pattern covering 80% of the opening and flow.
The intorduction of ANY additional “________” into the structure will increase fire intensity and fire spread.
Ventilation
Fast moving smoke tells you what about a fire?
Where the fire may be located.
How long can you flow water from a master stream (ie: Deck Gun, Mercury Monitor) without a water supply?
Between 60-90 seconds.
When flowing a Mercury Monitor or Deck Gun at 80 psi for smooth bore or 100psi for Fog Nozzle between 500-1000gpm, how far can the stream reach?
185 ft.
How far will a stream reach with a fog nozzle at 100 psi using the medium fog pattern?
50 ft
How far will a stream reach of fog nozzle at 100 psi, in a wide fog pattern?
25ft.
What is a Forward Lay?
Laying of Supply Line from the hydrant to the scene.
What is a Reverse Lay?
Laying Supply hose from the scene to the hydrant.
Typically from the Engine already on-scene, to the hydrant
What is a split lay?
When both engines layout from a identified point. Attack Engine proceeds to scene, Supply Engine to the hydrant.
