Tested annually. Cleaned and inspected monthly and after every use.
pg. 4
When did NFPA require ladders be marked with heat sensors?
- Page 4
Where should the heat sensor indicators be on the ladder?
Below the second rung and at the halfway point. Page 4
What temperature is the heat indicator set for?
300°F. pg 4
Aluminum, even if only exposed for a moment, can lose as much as _____% of its load capacity and can
continue to accumulate over its lifetime
25% pg 4
Firefighters should remember to grab the-_________ of an extension ladder if loaded heel out so as not to extend the ladder in the bed.
Fly section pg 5
Firefighters should grab the________ if loaded tip out so as not to extend the ladder in the bed.
Bed Section pg 5
What is the primary reason for laddering a building?
Fire fighter access and egress? Page 7
What are other factors to consider for laddering a building?
Victim removal. VEIS. Hose line advancement. Ventilation. Page 7
What is the priority order for ladder placement?
1.Fire floor.
2.Floor above the fire.
3.Adjacent compartments in roof if needed. Pg 7
If laddering the roof, what must be done?
Place two ladders in different areas to provide a secondary means of egress. Page 7
In order to select the most appropriate ladder for the task, how many feet should you estimate per floor for residential and commercial occupancy’s?
9 feet per floor for residential. 12 feet per floor for commercial. Page 7
A typical run of residential stairs is how long?
13 feet. Page 7
What is the approximate bedder length of a 2 section 28 foot extension ladder?
16’ 6”. Pg 9
Which leg should be used to perform the leg lock?
The lock shall be opposite of where the task will be performed. Pg 9
Where’s the correct position to heel a ladder?
On the outside of the ladder, not under it to monitor fire conditions, check for rescues, and stay away from falling debris. Page 9
If a victim is present at the window, how should the ladder be thrown?
To the side of the window and once raised, roll it to the sill to prevent the victim from jumping or reaching out to grab it when it’s not in position. Page 10
Where should a ladder placed solely for ventilation be?
Next to and up wind of the opening. Page 10
If laddering a roof, how many rungs should be above the roofline?
3 to 5. And make a general announcement on the fire ground channel. Page 10
How shall a balcony where the rungs are flush with the building be laddered?
Place the tip of the latter a minimum of two rungs above and near the end of the railing. Page 10
How shall a cantilevered balcony be ladder?
To the upwind side of the balcony. A minimum of two rungs above the railing height. Page 11
What is the minimum distance between the ladder and overhead lines?
10 feet. Page 12
If a ladder is ever moved from its original position what must be done?
Another ladder must be placed to the original location. Page 12
What types of ladders should be used for bridging?
Extension ladders. Page 16
To prevent panicked victims from jumping to the aerial, what aerial movements shall be used?
- Raise. 2. Rotate. 3. Extend. 4. Lower. Pg 18
If an aerial operator contacts power lines, what shall he do?
Movie aerial away. Stay on the turntable and warn others to stay at least 30 feet back. Notify incident commander. Notify power company. pg 19
If an aerial operator must get away from an aerial in contact with power lines, what shall he do?
Jump clear of the energized vehicle. Bunny hop away for at least 30 feet to avoid any grounding potential (step potential). Pg 20
An idea of the amount of time it takes for the master stream to begin operating is gained from constant what?
Multi company training. Page 20
If an effective master stream is sacrificed due to positioning outside of the collapse zone, how should the master stream be operated?
From the turntable only. Page 20
What are the three main uses for elevated stream operations?
- Extinguishment. 2. Exposure protection. 3. Flying Standpipe. Pg 21
What elevated master stream pattern should be used for attic fires?
Narrow fog/Straight stream. Page 22
What elevated master stream pattern should be used for exposure protection?
Fog stream. Page 22
What elevated master stream pattern should be used for Warehouse/commercial building fires?
Smoothbore nozzle.
What angle is best for fire knock down from the aerial platform?
30° angle. Page 23
If a large volume of fire is on several floors, where should the fire attack begin?
On the lowest floor moving up, attacking each successive floor. Page 23
If a large fire is spreading horizontally where should fire attack begin?
Stop the horizontal progress first and extinguish back towards it’s apparent origin. Page 23
What stream pattern is typically most effective for sweeping burning roof materials at the roof height.
Narrow fog. Page 24
The main purpose of the hose and associated connection on the bucket of the aerial is
Mop up or overhaul scenarios. Page 25
A straight aerial ladder may be converted to a flying standpipe
by
removing the tips from the pre-piped water way, leaving the stream straightener and applying
a reducer.
What is the difference between tower ladder vs ladder tower?
Tower ladder will typically only have an escape ladder mounted to the boom. Ladder tower has the ladder built into the bucket. Page 26
Elevated master stream operations can prevent auto exposure at over how many vertical feet?
Over 100 vertical feet (up to 150ft.) depending on the wind and placement of the truck company. Page 27
Prior to any master stream operation taking place on a high-rise, all personnel should be withdrawn to where?
To staging, at least two floors below. Page 27
Using a ladder to span distances resembling a bridge. This can be used to span two
buildings, trenches, etc.
Bridging –
Piece of rope or webbing spliced to form a loop through the eye of a metal
hook; used to secure hose to ladders or other objects and/or assist in the movement of the
hoseline
Tool
