Inspection of Slings, Lifting Devices, and Rigging Equipment

Posted October 18, 2013 12:00 AM by Milo

"Rigging equipment for material handling shall be inspected prior to use on each shift and as necessary during its use to ensure that it is safe. Defective rigging equipment shall be removed from service."- OSHA 1926.251(a)(1)

Fabric and cable slings are widely employed in our shops to lift and move bundles of bar stock in particular, as well as scrap totes, pallets, and other equipment when needed.

They often carry weights as much as 5 tons. over valuable equipment, and in the vicinity of employees.

A failed sling could cause thousands, or hundreds of thousands of dollars in damage as well as potential injuries.

Do you know where your slings and straps are?

Do you know their condition?

Do you have a process to assure compliance?

Dan Ignaziak at Sepco-Erie and his super cool team do.

Here are some photos of the Best Practice Sling inspection control system in use at Sepco Erie.

If you inspect it continuously, thereby not actually using it, it will stay safe. Hooray!

<Tips hat> Useful reminder.

This nonsense still appears from time to time, though.

It's even more important when that "rigging equipment" is for personal safety.

Been trying to get this replaced for 6 months now.

We in India have I.S specs.for all lifting equipments. These specs are based on B.S. specs as we normally follow them. Also there is Factory Act which specifies every six months testing and certifying of all these equipments. Such tests are conducted by Competent Person who is appointed by Factory Inpectorate. The Factory Inspector visits at random the factories and checks the records and all lifting equipments.

Suresh, No matter which code governs common sense prevails, the rigging equipments, tools and tackles are subjected to periodic/cyclic loading and at times reaching its rated capacity, due to usual wear and tear its practical to inspect it always before each use. I have heard about chain slings used in Steel manufacturing industry fail as every day or before every use inspection are not quite practical ... Especially where they are handling the molten coke or steel. OSHA guidelines are one of the most practical & best which come from years of experience and continuous improvements.

Take it to a bonfire, and burn it.

Looking at them they could use a washing. Over time fine dust collects in the fibers of the webbing. Under load the the webbing contracts the fibers are squeezed closer together. Pinching the dust particles between them. The some of the dust is silica which can have scarp edges and cut through the individual fibers. Over time this reduces the integrity of the webbing with out visual signs. Washing them will also increase the useful life.

By washing I mean just to use water, no chemicals to flush the dust out.

Humans have a built in survival mechanism.

While periodic inspections are necessary, the best way to prevent a sling from destroying a business, is with tort reform.

...Along with coming to grips with the fact that Darwin will never die. We can institute a billion rules, and stupid people will find a way to circumvent every one of them...in an instant.
