NWSA TT1 EXAM QUESTIONS
COMPLETE WITH VERIFIED ANSWERS
\.What is the minimum force that a positioning system anchorage must be able to
withstand? - CORRECT ANSWERS -2 times the MAF(Maximum anticipated
force) or 3,000 lbs
\.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? -
CORRECT ANSWERS -660 lbs. Synthetic rope has a safety factor of 10:1. That
includes the weakening factor of the knot
\.Exposure to ionizing radiation dopes what to the human body? - CORRECT
ANSWERS -IR can change cells and molecules in biological organisms
\.When is a trained signal person necessary - CORRECT ANSWERS -When a
crane can physically enter a powerline restricted area.
\.What three ways can a capstan hoist be powered - CORRECT ANSWERS -
Electric Gas and Hydraulic
\.When using tape and butyl to weatherproof a ground kit what is a critical step in
the process? - CORRECT ANSWERS -Always cut the tape with sciccors
, \.According to regulations, what is the maximum arresting force allowed to the
human body? - CORRECT ANSWERS -Maximum arresting force allowed on the
body is 1800 lbs. But our y-landyards reduce the force to half that

ANSWERS -3. (1 at the top above the hoisting grip. 1 at the base of the tower
on the vertical run, 1 at the cabinet)
\.how often must a fire extinguisher be inspected by a qualified person? -
CORRECT ANSWERS -Annually
\.What is a crown block? - CORRECT ANSWERS -Upper sheave assembly
attached to the tower. Sheave assembly = pulley or block
\.Exposure to Non IR does what to the human body - CORRECT ANSWERS -Has
thermal effects on the body
\.An overhaul ball provides what function in the operations - CORRECT
ANSWERS -Provides weight so the load line can travel back down to the
ground. Its apart of the load
