PLACEMENT CONSIDERATIONS. EXAM

What happens to the rungs of an aerial device when it is operated on level ground? -
ANS The rungs remain parallel with the earth's surface when raised in any position.
How do the rungs of an aerial device behave when operated on an incline? - ANS The
rungs will be tilted when the aerial device is raised to any position not in-line with the
apparatus.
What is the relationship between the angle of tilt and the shift in the center of gravity of an
aerial device? - ANS The tilt increases as the aerial device moves from an in-line position
to a 90-degree angle, causing a shift in the center of gravity towards the low side of the tilt.
What effect does a tilted aerial device have on the operation of the ladder? - ANS A
portion of the weight acts sideways on the aerial device, leading to increased difficulty of
operation as the sections may bind against each other.
When approaching an objective on excessive street grades, from which position should the
aerial device be positioned? - ANS The aerial device should be positioned from the
downhill position to maximize the angle of inclination.
1
, Why is it advantageous to position the aerial device from the downhill position? -
ANS Aerial devices offer maximum strength in the vertical position when approached
from the downhill position.
What should be done when traveling downhill to enhance the removal of ground ladders? -
ANS Pass the structure and spot back to the objective.
What should be done when traveling uphill to spot the aerial device? - ANS Stop and spot
before the objective unless maximum reach is necessary.
What is a key consideration when using aerial ladders to deliver personnel, tools, and
equipment? - ANS Aerial ladder personnel must be properly trained, and the fly section
should be extended outward 6 to 8 feet before personnel mount it.
What is the purpose of extending the fly section of the ladder before personnel mount it? -
ANS It eliminates the crossing rungs syndrome and allows personnel to stand on the end
portion of the fly section without moving rungs underneath.
What happens if a truck is stopped when traveling uphill and needs to remove rear loaded
ground ladders? - ANS Releasing the ladder locks can allow the grounded ladders to slide
onto the street.
What is the tilt at a 45-degree angle compared to a 90-degree angle? - ANS The tilt at a
45-degree angle will be one-half as great as the tilt at a 90-degree angle.
What can cause increasing difficulty of operation for an aerial ladder? - ANS The side
stress from a tilted aerial device, especially when loaded.
What is the effect of a greater tilt on the aerial device? - ANS The greater the tilt, the
greater the shift in the center of gravity and the force applied sideways.
What is the 'shifting rungs syndrome' in the context of aerial ladders? - ANS It refers to
the issue of moving rungs from the section underneath personnel when using the fly section.
