Quiz 3 Flashcards
a sprinkler head designed to react quickly and suppress a fire in its early stages.
Early-Suppression Fast-Response Sprinkler Head (ESFR)
a device that uses the Venturi principle to siphon a liquid into a water streams. The pressure at the throat is below atmospheric pressure to flow into the water stream. (NFPA 1145)
Eductor
the process of immediately reducing contamination of individuals in potentially life-threatening situations with or without the formal establishment of decontamination corridor. (NFPR 1072)
Emergency Decontamination
an urgent message, such as a call for help or evacuation, transmitted over a radio that takes precedence over all normal radio traffic.
Emergency Traffic
reactions that absorb heat or require heat to be added.
Endothermic
the removal or relocation of those individuals who may be affected by an approaching release of a hazardous material.
Evacuation
reactions that result in the release of energy in the form of heat
Exothermic
the process by which people, animals, the environment, property, and equipment are subject or come in contact with a hazardous material/weapon of mass destruction.
OR
any person or property that could be endangered by fire, smoke, gases, runoff, or other hazardous materials.
Exposure
a non-self-supporting ground ladder that consists of two or more sections traveling in guides, brackets, or the equivalent arranged so as to allow length adjustment.
Extension Ladder
a rapid, persistent chemical reaction that releases both heat and light
Fire
a connection through which the fire department can pump supplemental water into the sprinkler system, standpipe, or other system furnishing water for fire extinguishment to supplement existing water supplies.
Fire Department Connection (FDC)
the total energy content of combustible materials in a building, space or area including furnishing and contents and combustible building elements expressed in MJ.
Fire Load
the measure of the ability of a material, product, or assembly to withstand fire or give protection from it.
Fire Resistance
streams of water or extinguishing agents
Fire Streams
a geometric shape used to depict the four components required for a fire to occur; fuel, oxygen, heat, and chemical chain reactions.
Fire Tetrahedron
the range in concentration between the lower and upper flammable limits
Flammable Range (Explosive Limits)
a transition phase in the development of a compartment fire in which surfaces exposed to thermal radiation reach ignition temperature more or less simultaneously, and fire spread rapidly throughout the space, resulting in full room involvement or total involvement of the compartment or enclosed space.
Flashover
the minimum temperature at which a liquid or a solid emits vapor sufficient to form an ignitable mixture with air near the surface of the liquid or the solid.
Flash Point
a hose loading method in which the hose is laid flat and stacked on top of the previous section
Flat Hose Load
a protein-based foam concentrate to which fluorochemical surfactants have been added.
Fluoroprotein Foam
a covering of foam over a surface to insulate, prevent ignition, or extinguish the fire
Foam Blanket
a device or method of foam concentrate and water, in the mix ration required for the application
Foam Proportioner
a nozzle that is placed at the end of a fire hose and can be adjusted to produce a straight stream or to separate the water into droplets to produce a variety of fog streams
Fog-Stream Nozzle
a single-section ladder with rungs that can be folded or moved to allow the beams to be brought into a position touching or nearly touching each other
Folding Ladder
techniques used by fire personnel to gain entry into buildings, vehicles, aircraft, or other areas of confinement when normal means of entry are locked or blocked.
Forcible Entry
a sprinkler head with a liquid-filled bulb. The sprinkler head becomes activated when the liquid is heated and the glass bulb breaks
Frangible-bulb sprinkler head
individuals or crews operating independently of the established ICS structure
Freelancing
the reduction in pressure resulting from the water being in contact with the side of the hose. This contact requires force to overcome the drag that the wall of the hose creates
Friction Loss
a sprinkler head with an activation mechanism that incorporates two pieces of metal held together by low-melting-point solder. When the solder melts, it releases the link,and water begins to flow
Fusible-link sprinkler head
the physical state of a substance that has no shape or volume of its own and will expand to take the shape and volume of the container or enclosure it occupies
Gas
valves found on hydrants and sprinkler systems. Rotating a spindle causes a gate to move slowly across the opening.
Gate Valve
glass or transparent of translucent plastic sheet used in windows, doors, skylights, or curtain walls
Glazing
a water distribution system that depends on gravity to provide the required pressure. The system storage is usually located at a higher elevation than the end users of the water.
Gravity-Feed System
connecting plate made of a thin sheet of steel used to connect the components of a truss
Gusset Plate
