A) Only when the load is freely suspended

B) Irrespective of the load’s condition or attachment

C) Solely during specific hours of the day

D) Whenever the load is partly secured

 

Correct Answer: A) Only when the load is freely suspended

 

8. What happens to the safe working load of a pair of slings when the included angle exceeds 90 degrees?

 

A) The safe working load is considerably reduced

B) The safe working load is considerably increased

C) The safe working load remains unaffected

D) The safe working load is doubled

 

Correct Answer: A) The safe working load is considerably reduced

 

9. What potential issue may arise even if the wind speeds are below the set limit during a lifting operation involving loads with a large surface area?

 

A) Crane overload due to wind resistance

B) Unpredictable crane movements outside the radius

C) The occurrence of gusts of wind exceeding the set limit

D) Movement or swinging of the load causing the crane to go out of radius

 

Correct Answer: D) Movement or swinging of the load causing the crane to go out of radius

 

10. What risk arises when the accessory was previously operating near its safe working load and the leg angles exceed 90 degrees?

 

A) Overload on the lifting equipment

B) Improved load distribution across the accessory

C) Enhanced stability in the lifting operation

D) Reduced chances of equipment strain

 

Correct Answer: A) Overload on the lifting equipment

 

11. Why should slewing with a load be undertaken cautiously?

 

A) To ensure faster completion of the lift

B) To decrease the likelihood of load overshooting the landing place

C) To test the crane’s maximum slewing speed

D) To allow for heavier loads to be carried safely

12. What knowledge should slinger/signallers possess concerning lifting accessories and their prescribed limits?

 

A) Understanding the maximum lifting speed for each accessory

B) Knowing the structural integrity of each accessory

C) Knowing the safe working load and the consequences of exceeding those limits

D) Calculating the center of gravity for different lifting accessories

 

Correct Answer: C) Knowing the safe working load and the consequences of exceeding those limits

 

13. Why is it part of the slinger/signaller’s role to inspect the load before releasing any load-restraining or securing gear?

 

A) To speed up the unloading process

B) To ensure the load is heavier than anticipated

C) To prevent unexpected movement or shifting of the load

D) To intentionally displace the load for easier handling

 

Correct Answer: C) To prevent unexpected movement or shifting of the load
