A102.1 Ventilation (01/01/2015) Flashcards
[A102.1 Ventilation]
Ventilation is normally defined as:
The systematic removal of heat, smoke, and gases and replacement with a supply of cooler fresh air
[A102.1 Ventilation]
Ventilation is categorized by type:
Horizontal and Vertical
[A102.1 Ventilation]
The 2 types of ventilation can be achieved by these 3 methods:
- Natural
- Positive pressure
- Negative pressure
[A102.1 Ventilation]
PPV fan use is an example of what method of ventilation?
Positive pressure
[A102.1 Ventilation]
Using a fan set up blowing out of a window is an example of what method of ventilation?
Negative pressure
[A102.1 Ventilation]
The technique of making openings in the structure and allowing ambient winds, weather condition and convection to affect ventilation is an example of what method of ventilation?
Natural
[A102.1 Ventilation]
It is critical that ventilation is performed:
Properly and in coordination with fire attack
[A102.1 Ventilation]
Most structure fires will reach a _________ __________ state:
Ventilation controlled
[A102.1 Ventilation]
Coordinated fire attack/ventilation refers to the concept of:
Initiating ventilation prior to entry of the fire attack lines
[A102.1 Ventilation]
Which is preferable? Horizontal ventilation or Vertical ventilation:
Horizontal Ventilation
[A102.1 Ventilation]
Whitish colored smoke may indicate:
An incipient fire
[A102.1 Ventilation]
Brown smoke may indicate:
Wood or natural products
[A102.1 Ventilation]
Heavy, rolling, black smoke under pressure may indicate:
Heated, fuel rich smoke conditions that are ripe for rapid fire progression
[A102.1 Ventilation]
Fire through the roof is and indication that the fire has:
Self-vented
[A102.1 Ventilation]
Ventilation openings in structures create:
Flow Paths
[A102.1 Ventilation]
With no influences of ventilation, the flow of products of combustion are normally:
Away from the fire area inside the structure toward uninvolved areas and any openings
[A102.1 Ventilation]
Yellow/Greenish smoke under pressure may indicate:
Significantly oxygen-deficient fire with backdraft potential
[A102.1 Ventilation]
Black smoke may indicate:
Hyrdrocarbons, plastics and other synthetics
[A102.1 Ventilation]
The safest location for firefighters is the _______ side of a flow path:
Inlet
[A102.1 Ventilation]
An advantage of natural ventilation is:
The speed of implimentation
[A102.1 Ventilation]
A major disadvantage of natural ventilation is:
The firefighter lack of control of the flow path
[A102.1 Ventilation]
When using natural ventilation, firefighters should strive to vent with the wind:
To their back
[A102.1 Ventilation]
PPV should be considered the standard ventilation plan for offensive attack in a:
Residential structure
[A102.1 Ventilation]
What is a positive pressure attack?
A method of using PPV ventilation in conjunction with initial fire attack
[A102.1 Ventilation]
The most likely cause for PPV to not create an effective flow path is usually:
A closed interior door between the entry point and the exit vent opening
[A102.1 Ventilation]
If the fire attack team has made entry into the structure without the use of PPV, the starting of PPV fans should be avoided until:
The fire is knocked down, and there is no longer a possibility of creating rapid fire progression with the firefighters inside
[A102.1 Ventilation]
PPV fans may not be the best choice in:
Large structures with complicated layouts
[A102.1 Ventilation]
What should be used with a PPV fan to redirect the carbon monoxide created by the fan?
An exhaust tube
[A102.1 Ventilation]
Negative pressure ventilation is best suited for:
Post-fire smoke removal operations
[A102.1 Ventilation]
This should be conducted every time prior to roof operations:
Risk/benefit analysis and size-up of the roof support system
[A102.1 Ventilation]
Most residential structures can be effectively ventilated without:
Roof ventilation operations
[A102.1 Ventilation]
The safest way to accomplish vertical ventilation is:
From an aerial ladder
[A102.1 Ventilation]
Roof ventilation operations should be assigned to a crew and officer that is:
Experienced and skilled
[A102.1 Ventilation]
When firefighters are operating on the roof, always provide multiple:
Egress points unless working off an aerial
[A102.1 Ventilation]
One large hole is preferable to several small holes in vertical ventilation. A safe option is to make this size holes from an aerial:
2’ x 6’ or 2’ x 8’
[A102.1 Ventilation]
In roof operations, who should ensure that personnel are clear of the saw?
The officer
[A102.1 Ventilation]
It is preferable to start the cut with the firefighter’s:
Back to the wind (finishing the cut upwind of the ventilation hole)
[A102.1 Ventilation]
Ideally, this should be present during roof operations:
Charged hoseline
