Ventilation
Any means other than natural ventilation; may involve the use of fans, blowers, smoke ejectors, and fire streams.
Mechanical Ventilation
Intake hose that connects pumping apparatus or portable pump to a water source.
Suction Hose
Valve with an exterior barrel that can be rotated to adjust the nozzle's pattern.
Rotary Control Valve
Covering any object in the immediate vicinity of the fire with water or foam
Exposure Protection
Process of establishing the cause of a fire incident through careful investigation
Fire Cause Determination
Phenomenon of a strong air draft moving from ground level to the roof level of a building.
Stack Effect
Nonthreaded coupling commonly found on large diameter hose
Storz Coupling
Hose appliances used to combine two or more hoselines into one. Has multiple female inlets and a single male outlet.
Siamese Wye
Device used to secure a machine's power switches, in order to prevent accidental re-start of the machine.
Lockout/Tagout Device
Form of drain opening provided in outer walls at floor or roof level to remove water to the exterior of a building in order to reduce water damage.
Scupper
The use and application of high volume ventilation fans before fire suppression that are intended to force heat and smoke toward desired exhaust openings
Positive-Pressure Attack (PPA)
Notches or grooves cut into coupling lugs to identify by touch or sight the exact location of the higbee cut
Higbee Indicators
Minimum flow rate at which extinguishment can be achieved.
Critical Flow Rate
Member of the command staff responsible for monitoring and assessing safety hazards and unsafe conditions during an incident
Incident Safety Officer (ISO)
Exact physical location where the heat source and fuel come in contact with each other and a fire begins
Point of Origin
Techniques that use the wind, convection currents, and other natural phenomena to ventilate a structure without the use of fans, blowers, smoke ejectors, or other mechanical devices.
Natural Ventilation
Large diameter, collapsible piece of hose used to connect a fire pump to a pressurized water supply source; sometimes incorrectly referred to as soft suction hose.
Soft Sleeve Hose
Hose stream that stays together as a solid mass, as opposed to a fog or spray stream. Produced by a smooth bore nozzle and should not be confused with a straight stream.
Solid Stream
Physical configuration of the land or terrain; often depicted using contour lines.
Topography
What type of materials will produce misleading or inaccurate images for TIC while searching for hidden fires?
a. glass
b. wet drywall
c. hardwood flooring
d. exposed wood studs
A
Structures or separate parts of the fire ground to which a fire could spread.
Exposures
Portion of a coupling that serves as a point of attachment to the hose.
Shank
Hose appliance with one female inlet and multiple male outlets; the outlets are usually smaller than the inlet. Outlets are also usually gated.
Wye
In structural firefighting, a form of fire attack that involves directing fire streams toward the ceiling of a compartment in order to generate a large amount of steam in order to cool the compartment
Indirect Attack (structural)
How should firefighters extinguish large smoldering items such as mattresses, stuffed furniture, and bed linens during overhaul?
a. submerge the object in water to drench it
b. use a fog stream to maintain firefighter protection
c. take the items outside the structure to be extinguished
d. apply dry chemical extinguishing agents to the hot spots
