Building Construction
These loads include equipment, people, movement and materials not attached to the structure.
What are live loads?
Fly sections are found in this type of ladder.
What is an extension ladder?
Extension ladders generally use this type of rope as halyards.
What is manilla rope?
This is the most important rule of forcible entry.
What is Try Before You Pry?
This is a channeled pathway for fire ventilation via vertical openings.
What is vertical ventilation?
This is a structural element that transfers loads perpendicular to its length.
What is a beam?
Extension ladders that exceed heights of forty feet or more are required to be equipped with these stabilizing devices.
What are staypoles?
These are the two broad categories that modern rope falls into relating to shock load capacity.
What are static and dynamic?
This family or group includes the flathead axe, maul, and sledgehammer.
What are Striking tools?
This process occurs when a firefighter discharges a fog nozzle out of a window or other opening at approximately 30-60 degrees, in order to remove smoke or heat from a space.
What is hydraulic ventilation?
Non-combustible construction is referred to as this type of construction.
What is Type II?
DAILY DOUBLE: This NFPA Standard for Use, Maintenance, and Service Testing of Fire Department Ground Ladders.
What is NFPA 1932?
The "Kern" in Kernmantle rope accounts for approximately this much of the total rope strength.
What is 75%?
This type of glass is heat treated in order to increase its strength.
What is tempered glass?
This cut is made to determine roof covering and depth, sheeting material, rafter direction, and fire conditions.
What is an inspection hole or cut?
This is an extension of a wall past the top of the roof.
What is a parapet wall?
These are the major safety concerns before raising ground ladders.
What are overhead obstructions?
This the only knot recommended for use in forming a length of webbing into a load bearing loop.
What is a water knot?
This is the process of removing the key cylinder and operating the locking mechanism by alternative means.
What is the "through the lock" method?
The main advantage to this cut is that gases and flame spread are not allowed to proceed past a chosen line.
What is a trench cut?
Collapse zones are established to minimize risk of injury from collapse and falling debris. This is the recommended minimal distance for a collapse zone.
What is 1 1/2 the height of the structure?
With the correct distance from the building for the given height, a ground ladder will be at a safe climbing angle, ideally at approximately this degree.
What is 75 degrees?
This type of rope has an elongation of approximately 10-15% at normal safe working loads.
What is dynamic rope?
This type of window has small sections of glass that are operated with a crank mechanism and overlap when closed.
What is a jalousie window?
These contraindications refer to the use of this style of ventilation: Imminent or confirmed rescue of a firefighter, working fire attack, unknown fire location, inability to provide a proper exhaust point, and a structure that presents signs of over-pressurization or indicators of a hostile event.
What is PPV (Positive Pressure Ventilation)?
