Fire Behavior
Technically fire is a chemical reaction that requires what 3 things to occur.
What is FUEL,OXYGEN and HEAT.
Rescue and Extrication are covered under what NFPA.
What is NFPA 1001
Example of surface water supplies.
Rivers and lakes
Device held in place by a solder with a known melting temperature.
What is a fusible device.
Defined as a stream of water or other extinguishing agent after it leaves a fire hose and nozzle until it reaches the desired point.
What is a Fire Stream
Energy exists in what two states
What is Kinetic and Potential?
Kinetic- possessed by a moving object
Potential-energy possessed by an object that can be released in the future.
A rapid but thorough search that is performed either before or during fire suppression operations.
What is a primary search
A fire hydrant that receives water from only one direction is known as a
What is a dead end hydrant.
Device, sometimes called a visible products of combustion detector
What is a photoelectric smoke detector.
Water has the ability to extinguish fire in several ways. The primary was is by what.
What is cooling
The energy transferred from one body to another when the temperatures of the body are different
What is Heat
This part of the coupling is toward the nozzle
What is the female end.
The male coupling has lugs on its shank and indicates the water source.
This type of hydrant is used in climates where freezing weather is expected
What is a dry-barrel hydrant.
During combustion, minute particles and aerosols too small to be seen by the naked eye are produced. These invisible products of combustion can be detected by these devices.
What are Ionization smoke detectors
At 212 degrees Fahrenheit, water expands approximately how many times its original volume.
What is 1700 times.
The transfer of heat energy by the movement of heated liquids or gases.
What is convection
PASS definition
What is Personal alert safety system.
Two primary advantages of water
Can be conveyed long distances
Can be stored easily
Device that can detect light in the ultraviolet wave spectrum or light in the infrared wave spectrum.
What are Flame Detectors
The use of a fog stream in a direct or combination fire attack requires what to be provided ahead of the hoseline.
What is adequate ventilation.
The transition between the growth and the fully developed fire stages and is not a specific event such as ignition
What is Flashover
This should begin as soon as the first emergency vehicle approaches the accident scene
What is a scene size up.
The process of raising water from a static source to supply a pumper is known as
Drafting
What is insert wooden wedges
What two factors affect pressure loss or gain in a fire stream
What are friction and elevation.
These two terms describe a condition where flames move through or across the un-burned gases during a fire's progression.
What is Flame-over and rollover
Flameover is distinguished from flashover by its involvement of only the fire gases and not the surfaces of other fuel packages within a compartment.
This type of glass is manufactured from two sheets of glass that are bonded to a sheet of plastic sandwiched between them.
What is Safety or Laminated Glass
This person is appointed to determine the distance between pumpers and to coordinate water supply operations.
Who is the water supply officer.
This valve has a yoke on the outside with a threaded stem that controls the opening and closing of the gate.
What is Outside screw and yoke ( OS&Y ) valve.
Water Hammer
What is the sudden stop of water flow through a hose or pipe
During thermal layering of gases, these gases tend to be in the top layer.
What are the hottest gases.
This equipment comes in many different sizes and shapes and is used in many rescue operations.
What is CRIBBING
Device, typically uses a 1 1/2 discharge line to move water.
What is a jet siphon
Discharge water after the release of a cap or plug that is activated by some heat-responsive element.
What is a sprinkler
Discharges more than 350 gallons per minute and is fed by multiple 2 1/2, 3 inch or larger hoselines.
What is a master stream
Name 3 of the 6 conditions that may indicate a potential for a backdraft.
Pressurized smoke exiting small openings
Black smoke becoming dense gray/yellow
Confinement and excessive heat
Little or no visible flame
Smoke leaving the building in puffs or at intervals (appearance of breathing )
Smoke-Stained windows
Several methods can be used to prevent horizontal motion. The most common method is to to what to the vehicles wheels.
What is to chock.
Defined as force per area
What is pressure.
In fire service terms, pressure is most commonly thought of as velocity of water in a conduit.
Device capable of sensing a sudden increase or decrease in pressure
What is a water flow alarm device
Is effective as an extinguishing agent and vapor suppressant on Class B liquids because is can float on the surface of these fuels.
What is Fire Fighting Foam.
What is Natural Gas ( Methane )
Examples of hydrocarbons with vapor densities greater air ( 1 ) are ethane and propane. They tend to hug the ground.
When rescuers respond to any situation involving electricity, they should always do the following.
Assume the electrical lines or equipment are energized
Call the power provider to respond
Control the scene.
The pumper with the greatest pumping capacity should be located where.
FDC stands for
Fire Department Connection
The most common type of foam proportioner used in the fire service
What is an In-Line foam eductors.
Chemical and physical changes almost always involve an exchange of energy. Reactions that give off energy as they occur are called_______
What are Exothermic reactions.
At what point should rescuers remove their facepieces in an attempt to share with another firefighter or victim.
What is Never
This NFPA, Standard for Automotive Fire Apparatus, requires that apparatus on level ground be capable of filling at rates of at least 1,000 gallons per minute.
What is NFPA 1901
NFPA standard for the Installation of sprinkler systems.
What is NFPA 13
What is AFFF
What is Aqueous Film Forming Foam.
