Introduction
The NCCCO Rigger Level I Certification Exam assesses the foundational knowledge and practical skills
required to safely handle and move loads using rigging equipment. This practice test evaluates a
candidate's ability to inspect rigging gear, select appropriate slings and hardware, calculate load stresses,
recognize hazards, and apply OSHA and ASME standards in real-world scenarios. The examination
consists of multiple-choice and scenario-based questions designed to test critical thinking, problem-
solving, and professional judgment. Emphasis is placed on practical application, safety responsibility, and
ethical decision-making in dynamic workplace environments. Successful completion demonstrates
readiness to perform basic rigging tasks under qualified supervision.
SECTION ONE – QUESTIONS 1–100
Question 1
Which standard primarily governs slings used in rigging work?
A. ASME B30.5
,B. ASME B30.9
C. ASME B30.20
D. ASME B30.26
🟢 Correct answer: B
🔴 Explanation: ASME B30.9 is the standard that covers slings, including wire rope, synthetic web,
synthetic round, chain, and metal mesh. B30.5 covers mobile cranes, B30.20 covers below-the-hook
lifting devices, and B30.26 covers rigging hardware such as shackles and eye bolts.
Question 2
A wire rope sling shows broken wires clustered in one lay length exceeding the allowable limit. What
action is required?
A. Continue using if the load is light
B. Paint over the damaged area and return to service
C. Remove the sling from service immediately
D. Rotate the sling to redistribute the wear
🟢 Correct answer: C
🔴 Explanation: Broken wire concentration exceeding the allowable limit indicates critical damage. Per
OSHA 1926.251, wire rope must be removed if the total number of visible broken wires exceeds 10
percent of the total number of wires in any length of eight diameters. The sling must be removed from
service immediately.
Question 3
At a sling angle of 30 degrees from horizontal, what is the approximate sling angle factor?
A. 1.0
B. 1.155
C. 1.414
D. 2.0
🟢 Correct answer: D
,🔴 Explanation: The sling angle factor at 30 degrees from horizontal is 2.0, meaning each sling leg
carries twice the share of the load. The factor is 1.155 at 60 degrees and 1.0 only when the sling is truly
vertical.
Question 4
When installing U-bolt wire rope clips on a wire rope eye termination, the saddle should be placed on
which part of the rope?
A. The dead end of the rope
B. The live end of the rope
C. Alternating between live and dead ends
D. It does not matter which side the saddle is on
🟢 Correct answer: B
🔴 Explanation: The phrase to remember is "Never saddle a dead horse." The saddle (the formed part
of the clip) must be placed on the live end of the rope, with the U-bolt in contact with the dead end.
Question 5
A load with an off-center center of gravity will exhibit which behavior during a lift?
A. Lift evenly without rotation
B. Tilt toward the heavier side
C. Spin freely regardless of attachment points
D. Remain level automatically
🟢 Correct answer: B
🔴 Explanation: When the center of gravity is not centered between attachment points, the load will
tilt toward the heavier side. This indicates that the load weight is not evenly distributed, and the
rigging configuration may need adjustment.
Question 6
What is the minimum design factor for wire rope used in lifting applications?
, A. 3:1
B. 4:1
C. 5:1
D. 6:1
🟢 Correct answer: C
🔴 Explanation: Wire rope used for lifting must have a design factor of at least 5:1 according to OSHA
and ASME standards. This means the breaking strength must be at least five times the rated working
load limit.
Question 7
A rigger is assigned to lift a prefabricated steel beam using a two-leg sling configuration but fails to
account for sling angle reduction in capacity. What is the most immediate technical concern?
A. Increased crane counterweight requirements
B. Reduced effective sling capacity due to angle loading
C. Excessive wind loading on the crane
D. Over-lubrication of rigging hardware
🟢 Correct answer: B
🔴 Explanation: As sling angles decrease from vertical, tension in each leg increases significantly,
reducing the safe working capacity of the sling assembly. At 30 degrees from horizontal, tension
doubles compared to a vertical lift.
Question 8
Which hitch configuration provides the best load stability for a cylindrical load?
A. Choker hitch
B. Basket hitch
C. Single vertical hitch
D. Running hitch
🟢 Correct answer: B
