Mastering Safe Sling Use: A Key Guide for Lifting Operations

At Holloway Houston, We Focus on Top-Level Safety for All Lifting Work

Slings are vital for moving materials, and using them safely is key to stopping accidents and injuries. This detailed guide sets out important OSHA (Occupational Safety and Health Administration) rules for picking, checking, and using slings without risk. It’s based on the best ways the industry does things and aims to be a helpful reference, much like the guides Holloway Houston offers.

OSHA's Role in Sling Safety

OSHA has rules to keep workers safe across different jobs, and using slings without danger falls under these rules. While the exact rules might change a bit based on the type of work (general industry, construction, shipping), the main ideas stay the same. Employers must make sure that slings are:

• Right for the load: Selected based on the load’s weight, size, shape, and lifting conditions for safe handling.
• Checked often: To find any damage or faults that could make them unsafe.
• Used correctly: Following safe ways of working to stop overloading, wrong ways of attaching, and other dangers.

Key OSHA Rules for Sling Use: A Practical Guide

Using OSHA rules and the best ways the industry works, here’s a guide for safe sling use:

1. Picking the Right Sling

• Know the Load's Weight: Always find out how much the load you’re lifting weighs. Never go over the sling's load limit (Working Load Limit - WLL), which should be marked on the sling.
• Think About How It's Attached: The way the sling is attached (straight up, choked, in a basket) changes how much it can lift. Look at the sling maker's load chart for the specific way you’re attaching it and the angle of the lift. For example, a choked hitch typically reduces the lifting capacity compared to a basket hitch but may still have a higher working load limit than a straight lift, depending on the angle and sling type.
• Consider the Job Site: Think about where the sling will be used. In very hot or cold places, chemicals and rubbing can harm some slings. Slings made of polyester and nylon, for instance, shouldn't be used if it gets hotter than 194°F (90°C) or colder than -40°F (-40°C).
• Protect from Sharp Edges: Keep slings away from sharp parts of the load by using padding or covers. Putting a piece of leather or a special sling protector (sling protection products) can stop cuts and rubbing.
• Sling Material: Pick the right sling material (alloy steel chain, wire rope, synthetic web slings, round slings) for the job and what the load is like. Each material has its own good and bad points.

2. Checking Before Each Use (Frequent Check)

Trained Checker: The employer chooses a trained person to check slings and all parts attached to them every day before use or at the start of each work period. This person should know how to spot problems.

Look Closely: Check the whole sling for any signs of damage, including:

• Missing or hard-to-read labels.
• Damage from acid or strong chemicals.
• Signs of burning or melting.
• Holes, rips, cuts, snags, or broken threads (for synthetic slings).
• Broken wires or too much wear (for wire rope slings). OSHA says to take a sling out of service if there are ten broken wires spread out in one rope length or five broken wires in one strand in one rope length.
• Bent, twisted or stretched links (for chain slings). If a measured part of the chain is more than 5% longer, it should be taken out of service.
• Fittings (hooks, rings, etc.) that are pitted, rusted, cracked, bent, twisted, or broken. Hooks should be taken out of service if cracked, opened more than 15% wider than normal, or twisted more than 10 degrees.
• Stiffness or bending out of shape (for metal mesh slings).
• Too much wear, powdery fibers, broken or cut fibers, color changes, or rot (for fiber rope slings).

Take Out of Service: Any damaged or faulty sling must be taken out of service immediately and should not be used until it’s fixed and tested (if fixing is allowed) or replaced.

3. Regular Checks

Qualified Checker: In addition to the checks before each use, a qualified person must perform a full check at times that depend on how often the sling is used, how hard it’s used, and what’s been learned about how long similar slings last. OSHA suggests these checks should happen at least once a year.

Keep Records: A record of the most recent full check should be kept.

What to Check: This check is more detailed than the daily one and should look closely at the sling's overall state.

4. Using Slings Safely

• Attach Correctly: Make sure slings are attached in a way that keeps the load under control. Don’t use knots or other quick fixes to make slings shorter. Sling parts should not be twisted.
• Balance the Load: When using a basket attachment, make sure the load is balanced so it doesn't slip. The parts of the sling should hold the load from the sides above its center.
• Keep Clear: Keep all body parts away from where the sling touches the load and where the sling touches the lifting hook. Never stand in line with or next to the parts of a sling that are holding weight and never walk or stand under a load that’s hanging.
• Lift Smoothly: Avoid sudden jerks or impacts, which can put too much force on the sling.
• Protect Slings: Use padding to protect slings from sharp edges of the load.
• Center the Load: Make sure the load on the hook is in the middle of the hook’s curve, unless the hook is made for a load on its point.
• Don't Drag: Don’t drag slings on the ground or over rough surfaces.
• Choker Hitch Rules: When using a choker hitch, the choke point should only be on the main part of the sling, never on a joined part or fitting. A choke angle of less than 120 degrees shouldn't be used without lowering the allowed load.
• Don't Rest Loads: Don’t let loads rest on slings.
• Getting Slings Out: Don’t try to pull a sling out from under a load that’s resting on it.
• No Riding: Never ride on a sling or a load unless the load is specially made and tested for carrying people. Synthetic webbing slings should not be used as bridle slings on platforms that lift people.

5. Sling Labels

• Permanent Marks: Slings must have clear, permanent labels that show:
  • The maker's name or symbol.
  • The loads they can lift for each way of attaching and the angle these loads are based on.
  • The sling's size or diameter.
  • How many legs it has, if more than one.
  • A unique number or mark.
• Keep Labels Readable: The person using the sling must keep the label easy to read for the whole life of the sling. If the label is missing or can’t be read, the sling must be taken out of service.

6. Training

Trained Sling Users: Only people who are trained and know what they’re doing should be allowed to pick, check, and use slings. Training should cover:

• How to choose the right sling for the load and how it will be attached.
• How to check slings before use and regularly.
• Understanding load limits and how sling angles affect them.
• Safe ways of working and possible dangers.
• How to store and care for slings.
