RSP Load Handling & Safety Practices 2

Question 1

When a load begins to swing during a lift, what is the FIRST corrective action a signal person should take?

Accepted Answer

Signal the operator to stop all movement immediately

Answer

Stopping all crane movement immediately prevents the swing from worsening and gives the operator time to assess and control the situation safely.

Question 2

What does the term 'two-blocking' refer to in crane operations?

Accepted Answer

The hook block contacting the boom tip or sheave assembly

Answer

Two-blocking occurs when the hook block is hoisted up until it contacts the boom tip, which can cause the hoist line to break or the block to fail.

Question 3

Which factor is MOST critical when determining the center of gravity of an irregular-shaped load?

Accepted Answer

The weight distribution across the load's dimensions

Answer

The weight distribution across the load determines where the center of gravity is located, which dictates how rigging must be configured to keep the load stable.

Question 4

A rigger notices that a synthetic web sling has a UV-faded label and is slightly stiff. What should be done?

Accepted Answer

Remove the sling from service and tag it as defective

Answer

UV degradation and stiffness in synthetic slings are signs of material deterioration that reduce load capacity; the sling must be removed from service.

Question 5

What is the primary purpose of using a tag line during a crane lift?

Accepted Answer

To control load rotation and prevent uncontrolled swinging

Answer

Tag lines allow ground workers to control load orientation and prevent dangerous spinning or swinging without personnel having to touch the load directly.
