What should be checked about slings and shackles before lifting?

• A. Slings balanced and not twisted; shackles secure; rigging attached to appropriate lugs or load hook.
• B. Slings should be colored red.
• C. Shackles should be left loose.
• D. Slings are required only if requested.

Answer: (A)

Before lifting, focus on how the rigging will behave under load. Slings must be balanced and laid without twists so the load is carried evenly; a twisted or unbalanced sling can cause uneven loading and lead to premature failure or a dangerous shift. Shackles need to be secured with pins fully in place (and locked if the design requires) so they cannot open or slip during the lift. The rigging should be attached to the correct points on the load—appropriate lugs or the load hook—so the pulling forces are applied through the intended hardware and the load stays stable. Color, appearance, or looseness do not substitute for these checks. Slings aren’t optional—if the load needs rigging, it must be checked and used correctly every time.
