Proper Sling Use Toolbox Talk

Slings are one of the most common lifting tools on a jobsite, but they can fail fast when they are used the wrong way. A sling that is cut on a sharp edge, overloaded because of a bad angle, twisted during a pick, or attached to the wrong point can let the load shift, drop, or swing without warning.

This talk covers the basics of proper sling use before and during a lift. We will focus on choosing the right sling, checking condition and capacity, protecting it from damage, setting it correctly on the load, and knowing when to stop work before the lift turns unsafe.

Why This Matters

• Slings carry the full force of the load and any mistake in setup can lead to failure.
• Sling capacity changes based on hitch type, angle, and how the load is balanced.
• A damaged sling may hold at first and then fail once full tension is applied.
• Improper sling use can cause dropped loads, swinging materials, and serious struck-by injuries.
• Good sling practices help protect workers, materials, and equipment during every lift.

Common Hazards

• Using a sling with cuts, tears, broken wires, stretched links, or missing tags.
• Choosing the wrong sling type for the weight, shape, or surface of the load.
• Using sling angles that increase tension beyond the sling’s rated capacity.
• Letting slings run over sharp corners without padding or edge protection.
• Twisting, knotting, or bunching slings during setup.
• Using a basket, choker, or vertical hitch without checking how it affects capacity.
• Setting the sling on unstable or uneven pick points that let the load shift in the air.
• Using a sling on a load coated with mud, ice, oil, or loose material that makes it slip during the lift.

Safety Checklist

Before Work Begins

• Inspect each sling for damage, wear, missing tags, and defects before use.
• Verify the sling type and capacity match the load weight, hitch, and lift plan.
• Check the load for sharp edges, rough surfaces, and anything that could cut or crush the sling.
• Use edge protection where needed to keep the sling from being damaged under tension.
• Confirm the pick points are secure and placed to keep the load balanced.
• Make sure hooks, shackles, and other hardware are the correct size and rating for the sling.
• Review sling angles and make sure the planned setup does not overload the sling legs.

During Work

• Seat the sling properly in the hook and make sure it is not twisted or pinched.
• Lift slowly at first to check balance, sling position, and load control.
• Keep hands out of pinch points while the sling is being tensioned.
• Watch for sliding, shifting, or uneven loading as the load comes off the ground.
• Do not drag slings across concrete, steel, or rough materials after the lift starts.
• Keep workers clear of the fall zone and never allow anyone under a suspended load.
• Lower the load and reset the rigging if the sling moves, binds, or does not stay seated correctly.

Crew Talking Points

• What type of sling are we using, and is it rated for this load and hitch?
• Have all sling tags been checked and are they still readable?
• Where are the sharp edges, and what protection are we using?
• Are the sling angles safe, or are we adding too much tension to the legs?
• Will this load stay balanced with the current pick points and sling placement?
• Who is watching for shifting, slipping, or bad sling contact during the lift?
• Does anyone see a problem with the sling, hardware, angle, or load condition before we pick it?

Stop Work If

• The sling has damage, missing identification, or signs of wear that question its condition.
• The load weight, hitch type, or sling angle cannot be confirmed.
• Sharp edges are present and sling protection is missing or not holding in place.
• The sling is twisting, bunching, slipping, or riding against hardware the wrong way.
• The load shifts or hangs unevenly once tension is applied.
• The pick points are unstable, weak, or not made for lifting.
• Workers are in the fall zone or close to the suspended load.
• Anyone on the crew is unsure the sling setup is safe.

Final Reminder

A sling is only safe when it is the right one, in good condition, and set correctly. Inspect it, protect it, tension it carefully, and stop the lift the moment something looks wrong.
