NWSA TT1 EXAM 9 QUESTIONS WITH 100%
CORRECT ANSWERS
Once the lifting path is determined, the vehicle mounted capstan should be moved as close
as possible to what?
The lifting stage area
An antenna that can transmit 360°
omni-directional
When inspecting wire rope diameter, the actual diameter is slightly larger then the
specified diameter. T or F
True
what is the factor of safety specified for rigging equipment?
5 to 1
exposure to ionizing radiation does what to the human body?
permanently changes cells
a good rule of thumb is to stay 6 feet or more away from the centerline of an active
antenna. T or F
True
when you are using synthetic rope for lifting loads everyday, how often should it be
inspected?
daily
at minimum, how often should a competent rigger have refresher training?
refresher training every 2 years (rescue practice is annual)
what is the factor of safety specified for synthetic rope?
10 to 1
, the person operating the capstan needs a clear view of what?
the load and signal person
when using bolts or u-bolts with a slotted hole present, in what order are the components
installed?
flat washer, lock washer, then nut
which government organization regulates tower lighting?
FAA
it is correct to use a carabiner manufactured for PPE when lifting loads. T or F
False
if a synthetic rope has a breaking strength of 7,600 lbs, what is the maximum gross load
that can be lifted?
760 lbs (7,600÷10=760///10% of the breaking strength)
when must a hard hat be worn?
When it is mandated by employer policy. When overhead hazards are present. When customer
contract requires its use.
if a synthetic rope has a breaking strength of 6,600 lbs, and a bowline knot is tied to make a
lifting eye, what is the maximum gross load that can be lifted?
660 lbs (10% of breaking strength)
due to the resonance frequency and the high power of broadcast antennas, over exposure is
almost always a problem. T or F
True (the wavelength emitted by broadcast frequency, especially FM signal, is the same size as
the human body)
if you notice the impact indicator has been deployed while inspecting your equipment, what
should you do?
take it out of service immediately
