NCCCO RIGGER LEVEL I EXAMINATION COMPLETE
QUESTIONS AND DETAILED SOLUTIONS LATEST UPDATE
THIS YEAR JUST RELEASED
1.
Before attaching any rigging hardware, a rigger must determine the load's
approximate weight and identify what information is needed to verify it
accurately.
A. The crane's maximum capacity
B. The load weight and available load information
C. The operator's experience level
D. The hook block's color
Answer: B
Rationale: Knowing the actual or reliably established load weight is fundamental
to selecting rigging equipment with adequate capacity and maintaining a safe
lifting operation.
2.
A rigger discovers that the planned load path passes directly beneath an occupied
elevated work platform during a scheduled lift.
A. Continue because the crane operator controls the load
B. Move the personnel after the load begins traveling
C. Stop and address the hazardous travel path before lifting
D. Increase the lifting speed to minimize exposure
,Answer: C
Rationale: Personnel should not be exposed unnecessarily to suspended loads, so
hazardous travel paths must be corrected before the lifting operation begins.
3.
While inspecting a synthetic web sling, you notice several cuts extending partially
through its load-bearing fibers.
A. Use the sling only for lightweight loads
B. Tie knots around the damaged areas
C. Remove the sling from service
D. Reverse the sling before using it
Answer: C
Rationale: Significant cuts or damage to load-bearing fibers can compromise sling
strength and require removal from service according to inspection criteria.
4.
Why should a rigger use edge protection when a synthetic sling contacts a sharp
corner of the suspended load?
A. It increases the crane's rated capacity
B. It prevents cutting and abrasion damage to the sling
C. It eliminates the need for inspection
D. It makes the load lighter
,Answer: B
Rationale: Sharp edges can cut or severely damage synthetic sling fibers, while
appropriate protection helps preserve sling integrity during lifting.
5.
During a lift, a suspended load begins rotating unexpectedly because the center of
gravity was not aligned with the rigging arrangement.
A. Grab the load by hand immediately
B. Increase crane speed
C. Control the situation using appropriate taglines and safe positioning
D. Stand underneath the load
Answer: C
Rationale: Taglines can help control load rotation while keeping personnel
positioned away from dangerous pinch points and suspended-load exposure.
6.
Which condition most directly increases the possibility of shock loading a sling
during a crane lifting operation?
A. Smoothly taking slack from the rigging
B. Slowly raising a properly balanced load
C. Suddenly applying lifting force to slack rigging
D. Using properly rated hardware
, Answer: C
Rationale: Sudden loading can create forces significantly greater than the static
load weight, potentially damaging rigging components or causing failure.
7.
A shackle is selected for a lift, but its identification markings are illegible and its
rated capacity cannot be verified.
A. Use it if it appears undamaged
B. Use it only below half capacity
C. Do not use it until its suitability can be verified
D. Paint new capacity markings onto it
Answer: C
Rationale: Rigging hardware must have identifiable specifications sufficient to
verify its suitability; unknown capacity makes safe selection impossible.
8.
When selecting a sling for a load with an unusually narrow lifting point, which
factor deserves particular attention?
A. The sling's color
B. Contact geometry and potential stress concentration
C. The crane operator's preference
D. The sling manufacturer's logo
