  1. non-load bearing rope attached to a hoisted object to help steer it in a desired direction, prevent it from spinning or snagging on obstructions, or act as a safety line.
    tag line
  2. any facility in which a fire, accident, or natural disaster could cause substantial casualties or significant economic harm, through either property or infrastructure damage.
    target hazard
  3. measure of a materials ability to transfer heat energy to other objects; the greater the energy the higher the temperature.
  4. treated glass that is stronger than plate glass or a single sheet of laminated glass; safer than regular glass because it crumbles into chunks when broken, instead of splintering into jagged shards.  most commonly used in vehicle side and rear windows.
    tempered plate glass
  5. 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 the floor.
    thermal layering
  6. physical configuration of the land or terrain.
  7. defensive tactic that involves cutting an exhaust opening in the roof of a burning building, extending from one outside wall to the other, to create an opening at which spreading fire may be cut off.
    trench ventilation
  8. system used for sorting and classifying accident casualties to determine the priority for medical treatment and transportation.
  9. in the incident command system, a shared command role in which all agencies with geographical or functional responsibility establish a common set of incident objectives and strategies.
    unified command
  10. upper limit at which a flammable gas or vapor will ignite; above this limit the gas or vapor is too rich to burn.
    upper flammable (explosive) limit
  11. rope designed for any use except rescue; can be used to hoist equipment, secure unstable objects, or cordon off an area.
    utility rope
  12. weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and pressure.  density less than 1 is lighter than air.  density greater than 1 is heavier than air.
    vapor density
  13. measure of the tendency of a substance to evaporate.  the pressure at which a vapor is in equilibrium with its liquid phase for a given temperature; liquids that have a greater tendency to evaporate have higher vapor pressures for a given temp.
    vapor pressure
  14. walls with a surface layer of attractive material laid over a base of common material.
    veneer walls
  15. physical law stating that when a fluid, such a s water or air, is forced under pressure through a restricted orifice, there is an increase in the velocity of the fluid passing through the orifice and a corresponding decrease in the pressure exerted against the sides of the construction.
    venturi principle
  16. 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.
    vertical ventilation
  17. area between the hot and cold zones that usually contains the decontamination corridor; typically requires a lesser level of ppe.
    warm zone
  18. detector that recognizes movement of water within the sprinkler or standpipe system.  once movement begins the detector gives off an alarm.
    waterflow device
  19. force created by the rapid deceleration of water causing a violent increase in the pressure that can be powerful enough to rupture piping or damage fixtures.
    water hammer
  20. method of water supply by which mobile water supply apparatus continuously transport water between a fill site and the dump site located near the emergency scene.
    water shuttle operation
  21. any of a variety of hose appliances with 1 female inlet for a 2.5 in or larger hose and with 3 gated outlets, usually for a 2.5 in outlet and two 1.5 in outlets.
    water thief
  22. fire hydrant that has water all the way up to the discharge outlets; may have separate valves for each outlet or one for all.
    wet-barrel hydrant
  23. the side or direction form which the wind is blowing.
    windward side
  24. end of the rope used to tie a knot.
    working end
  25. hose appliance with one female inlet and multiple male outlets, usually smaller than the inlet.
