Tactical ventilation is performed during fire attack for this primary purpose.
Help control the fire
This type of mechanical ventilation involves artificially lowering the pressure inside the structure.
Negative pressure ventilation
This type of hose transports water from the pumping apparatus to the nozzle.
Attack
This specific type of hose coupling features the thread on the exterior.
Male
This type of hose roll is commonly used when storing hose in a storage rack.
Straight roll
Thi is the primary mode of heat transfer from one compartment to another in a structure fire.
Convection
This type of ventilation requires no additional personnel or equipment to set up and maintain.
Natrural horizontal ventilation
Fire hose is labeled and identified according to this specific measurement.
Inside diameter
This is the primary purpose of lugs found on a fire hose coupling.
Tightening and Lossening
Accordion
This rapid transition occurs when fresh air from ventilation is introduced into a room, causing gases to ignite.
Flashover
This air movement equipment is used specifically to perform hydraulic ventilation.
Hoselines and fog nozzles
This type of hose is designe to connect the pumping apparatus to a pressurized water source.
This feature on a coupling is a flattened angle at the end of the threads that helps prevent cross-threading.
Higbee Cut
To make loading LDH more efficient, many apparatus are equiped with this piece of hardware.
Hose roller
Maintaining control over this may improve visiblity inside structures so that interior crews can work more effectively.
Exhaust openings
To be effective, vertical ventilation requires a horizontal inlet opening at this location.
Booster hose is designed to be carries in this manner on the fire apparatus.
On reels mounted on the apparatus
Woven-jacket natural fiber
This preconnected hose load consists of folds laid into the hose bed in an S-shape.
Triple layer
When wind speeds are 10mph or faster, firefighters are safest working in this postion.
Wind at their backs (upwind)
This type of cut is performed to create a defensivle line ahead of a fire's spread.
Trench cut
Fire hose should be service tested at least this often after its initial placement in service.
Once a year
Exposure to this substance will react to rapidly separate the inner lining of the fire hose.
This hose load can be carried completely on the shoulder and clear of the ground, reducing the chance of catching on obstacles.
