Monthly inspection B. Annual inspection
C. Pre-use inspection D. Supervisor inspection Rationale: Pre-use inspections identify immediate hazards. 13. What is the danger of side loading a hook? A. Paint damage B. Hook failure C. Noise D. Reduced speed Rationale: Hooks are designed for vertical loads; side loading weakens them. 14. What is the center of gravity? A. Load color B. Load height C. Point where weight is evenly distributed D. Hook position Rationale: Proper lifting depends on aligning with the center of gravity. 15. Which sling type is best for delicate loads? A. Chain sling B. Wire rope sling
Rationale: Clear communication ensures safe lifting operations. 19. Which factor reduces sling capacity? A. Color B. Length C. Angle stress D. Tag presence Rationale: Smaller angles increase tension and reduce capacity. 20. What is a proof test? A. Visual inspection B. Load test to verify strength C. Cleaning process D. Tagging method Rationale: Proof testing confirms equipment can handle rated loads. 21. What type of knot is commonly used in rigging? A. Square knot B. Slip knot C. Bowline knot D. Overhand knot Rationale: Bowline creates a secure loop that won’t slip.
What is the risk of overloading equipment? A. Faster lifting B. Structural failure C. Better grip D. Less friction Rationale: Overloading exceeds design limits and can cause catastrophic failure. 23. What should be checked first before lifting? A. Paint condition B. Weather forecast C. Load weight and rigging capacity D. Crane color Rationale: Matching load weight to equipment capacity is essential. 24. Which is safest for sharp edges? A. Bare sling B. Chain only C. Use edge protection D. Increase load Rationale: Edge protection prevents sling damage. 25.
A. Maintenance B. Determining crane capacity C. Painting D. Cleaning Rationale: Load charts define safe lifting limits. 29. What is the purpose of a swivel? A. Add weight B. Prevent twisting of rigging C. Increase load D. Reduce length Rationale: Swivels allow rotation without twisting slings. 30. What happens if the center of gravity is misjudged? A. Smooth lift B. Load tilts or shifts C. Faster lifting D. Less tension Rationale: Incorrect balance leads to instability. 31. Which material is strongest for slings? A. Nylon B. Polyester
C. Alloy steel chain D. Cotton Rationale: Alloy steel chains handle heavy loads and harsh conditions. 32. What is the purpose of a hook latch? A. Increase weight B. Prevent load disengagement C. Improve speed D. Reduce friction Rationale: Latches secure the load within the hook. 33. What is a blind lift? A. Visible lift B. Operator cannot see the load C. Light lift D. Fast lift Rationale: Requires signal person for safe execution. 34. What is the best communication method? A. Shouting B. Standard hand signals or radio C. Guessing D. Silence Rationale: Standardized communication prevents misunderstandings.
What is rigging hardware made of? A. Plastic B. Wood C. High-strength steel D. Rubber Rationale: Steel provides necessary strength and durability. 39. What is the function of a crane boom? A. Balance load B. Lift and move loads C. Store equipment D. Reduce weight Rationale: The boom extends reach and supports lifting. 40. What is a critical factor in tandem lifts? A. Color matching B. Precise coordination between cranes C. Speed D. Noise Rationale: Synchronization is essential to avoid load imbalance. 41.
What is the main purpose of rigging plans? A. Decoration B. Ensure safe lifting procedures C. Reduce paperwork D. Increase speed Rationale: Planning prevents accidents and ensures efficiency. 42. What should be done in case of equipment failure? A. Continue work B. Ignore C. Stop operations immediately D. Speed up Rationale: Immediate stoppage prevents accidents. 43. What is a load limit tag? A. Decoration B. Label showing capacity C. Identification only D. Warning sign Rationale: Tags provide critical safety information. 44. What is proper rigging? A. Fast setup B. Correct selection and use of equipment
Rationale: Training builds knowledge and reduces errors. 48. What is an exclusion zone? A. Storage area B. Restricted area around lifting operations C. Break area D. Inspection zone Rationale: Keeps personnel safe from hazards. 49. What is a lifting plan review? A. Ignoring plan B. Checking and approving procedures C. Speeding up work D. Skipping steps Rationale: Review ensures plan accuracy and safety. 50. What defines an advanced rigger? A. Beginner knowledge B. Limited skills C. Expertise in complex lifts and safety procedures D. No training Rationale: Advanced riggers handle complex operations with high safety standards.
What is the primary risk of lifting over live shipyard operations? A. Better efficiency B. Reduced cost C. Dropped load hazards to personnel and equipment D. Improved visibility Rationale: Active work zones increase exposure risk to workers and equipment beneath the lift. 52. Which factor determines crane stability most? A. Operator age B.
