NCCER RIGGER LEVEL 2 PRACTICE EXAM
QUESTIONS AND CORRECT ANSWERS PLUS
RATIONALES 2025.
1. What is the primary purpose of using tag lines when rigging a load?
To control load movement
Tag lines help guide and control the rotation and positioning of the load,
reducing uncontrolled movement and improving safety.
2. According to OSHA, which of the following is required when working near
overhead power lines?
Maintain the minimum approach distance
The minimum safe distance must be maintained to prevent electrocution
hazards.
3. When using shackles in a rigging operation, what should be done if the pin
is bent?
Remove the shackle from service
Damaged rigging hardware must be removed from service immediately to
prevent failure.
4. What is the recommended way to inspect synthetic slings before use?
Check for cuts, abrasions, and broken stitching
, Visual inspection ensures the sling is not compromised, which could lead
to failure.
5. When hoisting personnel in a man basket, which standard applies?
ANSI/ASME B30.23
This standard provides guidelines for personnel lifting systems to ensure
safe practices.
6. Which hitch is most stable for lifting a symmetrical load?
Basket hitch
A basket hitch provides good load stability by balancing the load on both
sides of the sling.
7. The primary factor that determines the sling angle is:
The distance between the slings and the horizontal plane
Sling angles affect the tension on the sling; smaller angles increase
tension.
8. What must be done if a wire rope sling has broken wires exceeding limits?
Remove it from service
Damaged wire rope slings are unsafe and must be discarded if they
exceed allowable damage.
9. What should a rigger do before lifting an off-center load?
Calculate the center of gravity
Knowing the center of gravity ensures the load is balanced and lifts safely.
10.Which knot is commonly used to secure the end of a rope to an object?
Bowline knot
The bowline creates a secure loop that will not slip under load.
, 11.What is the purpose of a spreader bar?
To keep lifting slings vertical
A spreader bar prevents slings from pulling inward, reducing sling angle
stress.
12.When should a rigger reject a chain sling?
If it has a stretched link
A stretched link indicates overloading and potential failure.
13.What should be done when two cranes are used for a tandem lift?
Use a qualified lift director
Complex lifts require coordination and a designated person in charge to
maintain safety.
14.What should be done if a load is rigged and the weather changes to high
winds?
Postpone the lift
High winds can make lifts dangerous; operations should stop until
conditions improve.
15.What is the proper hand signal for “stop”?
Extend one arm and swing it horizontally
Hand signals must be clear and standardized for safety.
16.The term “D/d ratio” refers to:
The diameter of the load to the diameter of the rope
Affects bending stress and the lifespan of the rope.
