Identification Tags For Slings Must Include The

The Small Tag That Keeps Workers Alive

I once watched a rigger spend twenty minutes arguing with a foreman about whether a synthetic sling was rated for overhead lifting. The sling looked fine. No cuts, no fraying, no obvious damage. But there was no tag. None. And without that tag, the whole conversation ground to a halt.

That's the thing about identification tags for slings — they don't look like much. But that tag is often the difference between a safe lift and a catastrophic failure. A small piece of woven fabric or a metal plate with some stamped letters. It’s the paperwork that keeps people breathing at the end of the day.

The question isn’t whether you need it. It’s what that tag actually has to say.

What Is a Sling Identification Tag?

An identification tag for a sling is a permanently attached label or plate that carries essential information about that specific piece of rigging equipment. It’s not optional. Here's the thing — it’s not a nice-to-have. It’s required by OSHA, ANSI, and pretty much every serious safety standard in the book.

Think of it like the ID card your sling has to carry everywhere it works. Just like you wouldn’t trust a driver without knowing their license class or vehicle weight rating, you shouldn’t trust a sling without knowing its working load limit, material type, and inspection history.

What Information Must Be on the Tag?

Here’s where it gets specific. The identification tag for slings must include several key pieces of information:

The working load limit (WLL) — this is the maximum load the sling can safely handle under ideal conditions. Not the breaking strength. Not the ultimate failure point. The working load limit. These are very different things.

The type and size of the sling — whether it's a flat synthetic webbing sling, a round endless sling, a wire rope sling, or a chain sling. Plus the dimensions that matter for compatibility with hardware.

The manufacturing date or serial number — so you can trace when it was made and track its service life.

The material composition — especially critical for synthetic slings, where different materials behave differently under heat, chemicals, and UV exposure.

The inspection requirements — how often it needs to be checked and by whom.

Some tags also include the manufacturer name, batch or lot number, and maintenance schedule. For multi-leg slings, the angle limitations get stamped right on the tag too.

Why It Matters More Than You Think

Here’s what happens when you ignore sling identification tags. A crew grabs what looks like a 2-ton sling from the rack. They don’t check the tag because “it looks fine.” They use it to lift something heavier than the sling is rated for. The sling fails. Someone gets hurt.

That scenario plays out more often than safety managers want to admit. The tag isn’t just bureaucratic paperwork — it’s the last line of defense between a job site and a headline.

But it goes deeper than just preventing disasters. Proper tagging enables:

Accountability — you know exactly which sling did what job, when it was last inspected, and whether it’s still in service.

Efficiency — instead of guessing or testing, crews can grab the right sling for the right job the first time.

Compliance — OSHA inspectors don’t care if your sling looks fine. They care if the tag is legible, intact, and accurate.

Real talk: I’ve seen experienced riggers shut down entire operations because a tag was missing or illegible. Not because they’re being difficult. Because the liability is enormous.

How the Tagging System Actually Works

The identification tag for slings must include information that survives the sling’s entire working life. That sounds simple until you realize these tags have to withstand oil, dirt, UV exposure, abrasion, and temperature swings — all while staying readable.

Material Matters

Synthetic webbing tags are usually made of durable polyester or nylon with UV-resistant printing. They’re sewn directly into the sling webbing so they can’t be removed without destroying the sling itself.

Wire rope sling tags are typically metal plates, often stainless steel, crimped or welded onto the cable. They survive the abuse that would shred a fabric tag.

Chain sling tags are usually metal too, sometimes riveted or welded to a link. They have to handle the same punishment as the chain itself.

What Makes a Tag Legally Valid?

The identification tag for slings must include information that remains legible throughout the sling’s service life. A faded, torn, or damaged tag is functionally useless — even if you know what it originally said.

This is where a lot of job sites mess up. That said, they’ll try to reattach a fallen tag with tape or zip ties. That doesn’t count. The tag needs to be permanently affixed by the manufacturer or an authorized servicing agency.

Some companies use color-coding systems in addition to tags — red for 1-ton capacity, blue for 2-ton, etc. But color alone isn’t enough. The tag still has to carry the actual specifications.

Common Mistakes People Make With Sling Tags

I’ve been on enough job sites to know that people screw up sling identification all the time. Here are the big ones:

Removing or Damaging Tags

Some crews rip tags off because they catch on things. On top of that, others lose them during storage or transport. Either way, a missing tag means the sling sits unused until it gets re-tagged — which usually means sending it back to the manufacturer or a certified inspector.

Using Generic or Aftermarket Tags

You can’t just print a new tag on your office printer and call it good. The identification tag for slings must come from the manufacturer or an authorized party. Homemade tags are a compliance nightmare.

Ignoring Inspection Requirements

The tag often specifies how often the sling needs inspection. Others can go longer. Some synthetic slings need monthly checks. But ignoring the schedule printed on the tag defeats the whole purpose.

Assuming “Looks Fine” Is Enough

This one kills me. A sling might look perfect, but if the tag says it’s been in service for five years and your company policy requires retirement after three, that sling is done. The tag doesn’t lie.

Practical Tips That Actually Work

Here’s what I’ve learned from watching good rigging supervisors and terrible ones:

Make Tag Checks Part of Every Lift Plan

Before any lift, someone should be checking the tag. And not just glancing at it — actually reading it. Does the WLL match the load? Is the sling appropriate for the material being lifted? Is the tag intact and legible?

Store Slings Properly

How you store slings directly affects how long their tags stay readable. Now, don’t just throw them in a pile. Hang them, rack them, or store them in a way that protects both the sling and its tag from unnecessary wear.

Replace Damaged Tags Immediately

If a tag is torn, faded, or partially missing, treat it like the sling has no tag at all. In practice, get it inspected and re-tagged by a qualified person. Don’t try to wing it with partial information.

Keep a Digital Backup

Some forward-thinking companies photograph every tag and maintain digital records. Which means when a physical tag gets damaged, they can still verify the sling’s specifications. It’s not a replacement for the physical tag, but it helps during transitions.

Train Everyone, Not Just Riggers

The identification tag for slings must be readable by anyone handling the equipment. That means laborers, crane operators, and even supervisors need to understand what to look for. A quick training session can save hours of confusion later.

FAQ

What happens if a sling has no tag? It cannot be used. Period. OSHA considers an untagged sling to be unidentifiable, which means it fails inspection automatically.

Can I replace a lost tag myself? No. Tags must be replaced by the manufacturer or an authorized agency. DIY tags are not compliant.

How often should sling tags be inspected? Every time the sling is used. The tag should be checked for legibility, damage, and accuracy before each lift.

What if the tag is faded but I know the specs? Still not compliant. The tag must be legible to anyone who needs to verify the information.
