If a building is less than ______ stories tall the arial ladder is placed outside the pumper. (in regards to closest to the fire occupancy)
5
______ operations are required when a pumper must be supplied from a static water supply source such as a dry hydrant, storage tank, lake, or stream
Drafting
________ is implemented when numerous units are responding to operate at the same incident, particularly those that require mutual aid or result in the transmittal of multiple alarms
Level 2 staging
In tandem pumping operations apparatus may be located up to ____ feet apart
300
Any wildland fire attack should begin with the apparatus positioned in an _____
Anchor point
Apparatus should maintain a clear zone of at least _____ ft from railroad tracks to prevent contact with objects on the railroad cars
30 ft
At 212 degrees F (100 celsius) water os converted to steam and occupies approximately ________ its original volume
1700 times
The pressure in a system before it flows from a hydrant is considered ______ for fire service purposes
Static
The fire service definition of _______ is that part of the total pressure lost while forcing water through a pipe, fittings, fire hose, and adapters
Friction loss
_________ are large pipes with relatively widespread spacing that convey large quantities of water to various points of the system for local distribution to smaller mains
Primary feeders
For fire protection purposes, ordinary fresh water is considered to weigh 62.4lb/ft cubed or _____ lbs per gallon
8.3
In the fire service ______ refers to the height of a water supply above the discharge orifice
Head
The pressure losses or gains due to gravity are called ….
Elevation pressure
_____ is currently the most commonly used synthetic foam concentrate. Its formula consists of flourochemical and hydrocarbon surfactants combined with solvents to create a higher boiling point. The flourochemical surfactants reduce the surface tension of the water in the foam solution to a degree that a thin aqueous film is spread across a fuel product as the foam solution is applied
AFFF
The _______ is a basic foal proportioner that is designed to be attached directly to the pump panel discharge or connected at some point in the hose lay. In order for this device to function effectively, the driver/operator mist follow the manufacturer’s guidelines that specify the correct pressure and distance between the eductor and appropriate nozzle.
In-line educator
Mixture of foam concentrate and water before the introduction of air
Foam solution
Regardless of the type of tank, foam storage must be______
Airtight
The formula of class a foam includes hydrocarbon surfactants that reduce the _______ of the water in the foam solution
Surface tension
For any given situation the proper distance between the objective and the aerial apparatus is the distance that affords the maximum stability, the best climbing angle, and________. This distance should be consistent with the ladders planned use and the conditions at the emergency scene
Adequate extension
Dynamic loads:
Loads that involve motion
The long standing fire service standard has been to provide ____ feet of clearance between aerial device and overhead high voltage lines energized from 600-50,000 volts and _____ feet of clearance for high voltage transmission lines over 50,000 volts
10ft, 50ft
Stability of aerial apparatus can be improved by operating the aerial device in line with the ________
Longitudinal axis (apparatus body)
Apparatus position should provide the maximum degree of ______ & _____ to the building to the firefighters using the aerial device
Safety and access
The two advantages of positioning an aerial apparatus on the corner of the building when using device for rescue:
- You can potentially reach victims on two sides of the building
- You are potentially safer if structural collapse occurs
In situations that require using aerial apparatus for rescue, the main objective is to reach as many victims or points of egress as possible with a _________
Minimum number of aerial movements
Victim rescue priority from highest to lowest:
- Most severely threatened by conditions of the hazard
- Largest number of groups of people
- Remainder of people in the hazard area
- People in exposed areas
When maneuvering any aerial device to reach a victim trapped in an elevated position, the aerial device should initially be aimed ______ and then ______ to prevent him/her from attempting to jump onto the ladder
Above the victim then lowered
When using an aerial ladder for rescue from a window the first rung of the ladder tip should be placed even with the _______
Windowsill
Aerial platforms should be placed so that the bottom of the platform is _____ the edge of the roof
Just above and over
The tip of an aerial ladder should extend at least ____ ft above the roof line
6ft
Exterior fire attack that is limited to controlling the spread of a fire with an emphasis on exposure protection
Defensive attack
Fire spreads to exposures either by ____,______or ______
Conduction, convection, or radiation
When protecting exposures with elevated master streams, water applied _____ the exposure more effectively absorbs the heat energy developed on the surface of the exposure and reduces its ability to catch fire
Directly on
________ means perception of one’s surrounding environment and the ability to anticipate future events
Situational awareness
When possible a ______ will allow for maximum coverage of the exposure
Fog pattern
