IFSTA Pumping And Aerial Apparatus Driver/operator Handbook Flashcards
When positioning an apparatus, _______ is the first tactical priority at any incident
Life safety
When positioning for exposure protection, consider _________ as a potential exposure.
The apparatus
With apparatus placement one exception to the uphill rule involves…..
Wildland fires
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
