Sample NCCCO Rigger Level I Practice Questions

Try these sample questions to review concepts for the NCCCO Rigger Level I exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 110+ question experience with AI tutoring.

1Under OSHA 1926.1401, who qualifies as a qualified rigger for assembly and disassembly or basic lifts?
A.Any worker assigned to the crew that day
B.A person qualified for the specific rigging task
C.Only a person who holds a state journeyman license
D.Only a person who has worked five years on cranes
Explanation: OSHA 1926.1401 defines a qualified rigger as a rigger who meets the criteria for a qualified person. The employer must determine that the worker is qualified for the specific lift based on demonstrated knowledge, training, experience, or applicable credentials. A card or time on the job alone does not establish task-specific qualification.
2Which standard primarily governs slings used in rigging work?
A.ASME B30.5
B.ASME B30.9
C.ASME B30.20
D.ASME B30.26
Explanation: ASME B30.9 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.
3A sling is rated 4,000 lb vertically, and its manufacturer lists twice that capacity for a balanced basket with vertical, parallel legs. What is that basket rating?
A.2,000 lb
B.4,000 lb
C.6,000 lb
D.8,000 lb
Explanation: Under the stated manufacturer rating, the balanced true-vertical basket is 2 × 4,000 = 8,000 lb. This factor must not be assumed for an unstated product or geometry; sling angle, D/d, balance, and the manufacturer's table can reduce the applicable rating.
4How should a rigger determine a sling's rated capacity in a choker hitch?
A.Use the choker capacity on its tag or manufacturer chart
B.Assume one fixed reduction for every sling
C.Treat choker and straight-hitch ratings as equal
D.Use twice the straight-hitch capacity
Explanation: The sling identification and manufacturer tables control the choker rating. The relationship to vertical capacity varies with sling construction and can be reduced further by a small choke angle, so a universal percentage must not be assumed.
5What is the minimum recommended sling angle from horizontal during a two-leg lift?
A.15 degrees
B.30 degrees
C.60 degrees
D.90 degrees
Explanation: Industry guidance uses 30 degrees from horizontal as the normal minimum. Below 30 degrees, tension rises sharply and the configuration requires specific approval by a qualified person and compliance with manufacturer limits rather than routine use.
6At a sling angle of 30 degrees from horizontal, what is the approximate sling angle factor (load multiplier per leg)?
A.1.0
B.1.155
C.1.414
D.2.0
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, 1.414 at 45 degrees, and 1.0 only when the sling is truly vertical. This is why 30 degrees is the practical minimum.
7When installing U-bolt wire rope clips on a wire rope eye termination, which is correct?
A.Place all saddles on the dead end of the rope
B.Place every saddle on the live end of the rope
C.Alternate the saddles between live and dead ends
D.It does not matter which side the saddle is on
Explanation: The phrase to remember is, Never saddle a dead horse. The saddle (the formed part of the clip) goes on the live, load-bearing side, and the U-bolt presses against the dead end. Reversing this crushes the live rope and severely weakens the termination.
8Under OSHA Table H-2, what is the minimum number of drop-forged U-bolt clips for 1/2-inch improved plow steel wire rope?
A.2
B.3
C.4
D.5
Explanation: OSHA 1926.251(c)(5) Table H-2 lists three drop-forged clips for 1/2-inch improved plow steel wire rope, with 3-inch minimum spacing. The table lists four clips for other clip material, and proprietary systems must follow their manufacturer instructions.
9Which inspection condition requires immediate removal of a synthetic web sling from service?
A.Slight surface fuzzing from normal use
B.Cuts, holes, or load-bearing-web tears
C.A sling tag that is dusty but readable
D.Light dirt from a clean job site
Explanation: ASME B30.9 lists cuts, holes, tears, snags, broken stitching in load-bearing splices, melted or charred areas, and missing or illegible tags as removal-from-service conditions for synthetic web slings. Surface fuzz alone is generally not a removal condition.
10Which sling tag information is required before the sling can be used?
A.Only the manufacturer name
B.Only the date of purchase
C.Manufacturer, sling ID, and applicable hitch ratings
D.Only the rated capacity for vertical use
Explanation: ASME B30.9 requires sling tags to show the manufacturer name or trademark, sling identification, rated loads for hitches in use, and other identifying information. A sling with missing or unreadable tag information is removed from service until properly identified.

About the NCCCO Rigger Level I Exam

The CCO Rigger Level I certification covers basic rigging knowledge and practical skill: lift scope, technical knowledge, inspection, sling and hardware use, load control, connections, and specified knots. Initial certification requires the written and practical examinations to be passed within the applicable 12-month window.

Exam sponsor: NCCCO (written via OPT, EOT, or TCT; practical at NCCCO-accredited test sites). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

60-question Level I written exam plus a Level I practical exam covering pre-use inspection, hitches, connections, and basic knots

NCCCO Rigger Level I: Suggested Study Strategy

1Master the OSHA 1926.1401 qualified-rigger definition. Many Level I questions test the difference between qualified rigger requirements at Level I (basic lifts, assembly/disassembly) and Level II (complex lifts).
2Memorize the sling angle factors: 90 degrees = 1.0, 60 degrees = 1.155, 45 degrees = 1.414, 30 degrees = 2.0. Below 30 degrees from horizontal is the practical danger zone.
3Use the sling tag, manufacturer data, hitch, angle, and configuration to determine capacity; do not assume one universal choker reduction.
4Know wire rope clip counts: 3 clips for 1/2 inch, 4 clips for 3/4 inch, 5 clips for 1 inch, spacing 6 rope diameters apart, saddle on the live end.
5Treat round-sling color as an identification aid only when supported by the applicable tag and manufacturer system; verify rated capacity from current identification data.
6Drill removal-from-service criteria for each sling type. Inspection is 30 percent of the written exam.
7Know which standard governs what: B30.9 for slings, B30.10 for hooks, B30.20 for below-the-hook devices, B30.26 for hardware.
8Keep preparation tied to the Level I outline; ASME B30.5 appears in the handbook's Level II-only reference list.
