Heat transfer by circulation within a medium such as a gas or a liquid.
What is Convection.
100
If not in a scabbard, carry the axe this way.
What is with the blade away from the body.
100
Before raising a ladder you must check for these.
What is overhead obstructions.
100
This is the highest incident priority.
What is life safety.
100
Designed for use in climates that have freezing temperatures, the main control valve of this type of hydrant is located at the base of the hydrant below the frost line.
What is dry-barrel hydrant.
200
This stage of a fire occurs when all combustible materials in the compartment are burning.
What is Fully Developed.
200
Two common tools used in combination for forcible entry are the flat-head axe and the Halligan tool, a combination of tools known as this.
What is the Irons.
200
On average a commercial story is this height.
What is 12 feet.
200
This ventilation cut is used as a fire break in narrow attic spaces.
What is trench cut.
200
In general, all fire hydrant bonnets, barrels, and foot pieces are made of this.
What is cast iron.
300
Outcome of combustion in a confined space in which gases tend to form into layers, according to temperature, with the hottest gases found at the ceiling and the coolest gases at floor level.
What is Thermal Layering.
300
If you can see the hinges of a swinging door, it swings this direction.
What is towards you.
300
Rope or cable used for hoisting and lowering the fly sections of an extension ladder.
What is Halyard.
300
This type of ventilation is ventilating at a point above the fire through existing or created openings and channeling the contaminated atmosphere vertically within the structure and out the top. This is done with openings in the roof, skylights, roof vents, or roof doors.
What is Vertical ventilation.
300
A minimum of this distance of water above and below the hard intake strainer is usually needed for it function properly and avoid picking up silt and debris.
What is 24 inches.
400
A condition where the unburden fire gases that have accumulated at the top of a compartment ignite and flames propagate through the hot-gas layer or across the ceiling.
What is Rollover.
400
Used with a Halligan-type tool or other prying tool, this tool is forced behind the ring and face of the cylinder until the wedging blades bite into the cylinder. Once set, the prying tool is used to pull this tool and the lock cylinder from the door.
What is K-tool.
400
During operations involving entry or rescue from a windowsill, the proper placement of a ladder is this.
What is the tip just below the windowsill.
400
To perform hydraulic ventilation, a fog nozzle is set on a wide fog pattern that will cover this percent of the window or door opening through which the smoke will be drawn or pulled.
What is 85% to 90%
400
Water supply system that relies entirely on the force of gravity to create pressure and cause water to flow through the system. The water supply, which is often an elevated tank, is at a higher level than the system.
What is gravity system.
500
Thermal energy or heat is this type of energy, transferred from a high-temperature substance to a low-temperature substance.
What is Kinetic Energy.
500
This type of glass should be broken by striking the glass at the bottom corner with the pick end of a pick-head axe.
What is tempered plate glass.
500
Heat sensor labels are required on metal and fiberglass ladders, placed on the inside of each beam, below the second rung from the tip of each section. The heat sensor is preset to this temperature.
What is 300 F (149 C)
500
Before stepping off a ladder or other place of safety onto the roof of a burning building - especially if the roof surface is obscured by smoke or darkness - firefighters should do this.
What is sound the roof.
500
This NFPA , Recommended Practice for Fire Flow Testing and Marking of Hydrants, sets standards for hydrant top and nozzle cap colors based on the fire flow.
What is NFPA 291
