Questions and correct Answers (Verified Answers)
with Rationales 2026
NCCCO/OSHA/ANSI Level II standards, covering load calculations, rigging gear
inspection, sling angles, hardware, signaling, and safety practices.
1. What is the minimum sling angle recommended for most rigging lifts to avoid
excessive tension?
A. 15° B.
20°
C. 30°
D. 45°
✅ Rationale: Sling angles below 30° cause dangerously high tension in the sling
legs.
2. When using a basket hitch with two sling legs, what percentage of the load
does each leg carry at a 90° angle?
A. 25%
B. 50%
C. 50%
D. 100%
,✅ Rationale: At 90°, the load is equally divided, so each leg carries 50%.
3. What is the main reason for using a spreader bar in rigging?
A. To increase load weight
B. To reduce sling length
C. To reduce sling angle and prevent sling damage
D. To increase hook size
✅ Rationale: A spreader bar helps maintain proper sling angles and reduces
stress on sling legs.
4. How often must rigging equipment be inspected according to OSHA?
A. Every 6 months
B. Before each use and periodically
C. Annually
D. Only after failure
✅ Rationale: OSHA requires inspection before each use and periodic detailed
inspections.
5. Which of the following is NOT a common cause of sling failure?
A. Overloading
B. Improper sling angle
C. Proper storage
D. Abrasion
, ✅ Rationale: Proper storage prevents failure, not causes it.
6. When rigging a load with a single synthetic sling, what should be avoided?
A. Using a basket hitch
B. Twisting or knotting the sling
C. Using proper sling protection
D. Inspecting sling before use
✅ Rationale: Twisting or knotting weakens synthetic slings and can cause
failure.
7. The maximum allowable elongation for synthetic web slings under normal use
is typically:
A. 1%
B. 3%
