Large-scale material movement can not afford any kind of loss caused by accidents. These accidents occur because of failure of equipment or human error. If we talk about the heavy movement of goods, webbing slings are used to lift them. Instead of metal chains, these nylon and polyester straps are used, which are cost-effective. Furthermore, they are available in different sizes.
What needs to be discussed here is the synthetic web sling inspection routine. How often should you inspect these webbing slings at your workplace to avoid accidents? It is a responsibility of a field supervisor to ensure the inspection of all the webbing slings before starting operations. On a monthly or semi-annually basis, inspection is mandatory. There are many reasons why a webbing sling needs to be inspected because one negligence can cause lots of damage. What you need to do is see some signs of damage, which we have mentioned below.
Marks of Tearing, Pilling, and Worn-Out Stitches
Tons of weight are lifted by webbing slings, and they are one of the secure ways of handling massive objects. However, wear and tear are inevitable, and need to be inspected after some months or weeks. If you detect any torn threads, that means your webbing sling needs to be tested. Light or mild is also a serious concern because it may break during the operation. Tensile pressure and the rough surface can make webbing slings lose their strength after some time. It is usual, and you must inspect before the sling finally breaks down. You can find these apparent signs on the surface of slings or have them inspected by an expert.
Unreadable or Illegible Safety Label
If a webbing sling’s label is damaged or unreadable, you need to remove it. There is a reason why a label is installed in it. Safety labels must be inspected before using web slings. All the details are mentioned on it about material type, weight-bearing limit, angle of the sling, length, code, inspection standard, and company’s name. This information is important before using a sling to avoid mistakes. If you select a sling with low strength, it may break down slowly or even suddenly. Moreover, there are warning signs mentioned on the label, which show the usage method and angular movement. Operators in supply chain and logistics industries have to be cautious of this warning label.
Any Damage Caused by Chemical, Heat, and UV Rays
Chemicals are dangerous for almost every type of material. In the case of web slings, you need to look for damage caused by chemicals like acid and caustic. Acid can melt many types of materials, especially nylon. If you have a nylon sling, you need to look for any damage caused by acidic material. If you use a polyester sling, you need to find any marks caused by caustic material. Both types of chemicals can damage the webbing sling, which can break at any time if pressure is applied to it.
Since they are made of polyester and nylon, they must be protected from heat. Too much heat can melt the sling where it gets most contact with fire or hot objects. Even sunlight can damage and break the threads of web slings. UV rays can penetrate the plastic and it can reduce its life. In Addition, high temperatures can damage webbing slings too quickly because their polyester strands can shrink because of heat. If you find any burn marks on the slings, time to replace them.
Look For Any Cuts, Abrasions, Holes, or Knots
Using slings on objects with sharp edges can cause abrasions and cuts on them. You need to inspect your slings more frequently. If you find any marks of damage, it is time to change the slings. Moreover, if you inspect holes in slings, it is a sign that they may break down soon. Cuts, holes, abrasions, and every torn spot of a sling are identified as risk factors. Some people ignore knots, which are also a sign of a problematic sling. A knot can reduce the breaking strength of the sling, which is a risk of an accident.
Measure the Length to Meet the Minimum Criteria
Slings have specific lengths, which need to be ensured before using them. Synthetic web sling inspection of length is necessary because a short sling for a long purpose can cause problems. Also, it will have an impact on the tensile strength of a sling. Inspect the sling if it has been cut or shortened because of any reason. If you find two different slings tied together, remove that sling immediately. This kind of sling can break at any moment.
Conduct Professional Standard Tests
There are many standards in the industry, which are followed for the testing of webbing slings. You need to have your webbing slings tested if you have doubts about them. A number of verified and well-known standards are followed for them. They are ASME B30.9, EN 1492-1, EN 1492-2, OSHA 1910.184, and ANSI/ASME B30.10.
This synthetic web sling inspection is important for the safety of workers and materials during the movement of goods on-site. Construction, supply chain, shipping, logistics, and similar industries follow these standards for the testing of webbing slings. If any webbing sling fails to succeed, it is discarded.
Safety Tips for Web Slings Usage
To avoid any accident, one needs to do a synthetic web sling inspection. These precautions can help you if you use webbing slings at your workplace.
1. Cover the web slings with protective layers.
2. Avoid pulling slings on rough or abrasive surfaces.
3. Prevent contact between web slings and sharp objects.
4. Do not use a webbing sling if it is already showing signs of damage.
5. Cut off the eyes of damaged slings to prevent reusability.
6. If a sling is in poor condition, discard it by cutting it into small pieces.
7. Do not weld the broken hooks, change them instead.
8. Do not leave web slings in direct sunlight or extremely hot temperatures.
9. Avoid using nylon slings for acidic materials and polyester slings for caustic materials.
Using the right type of webbing sling for the right purpose will increase the success rate, and it will also get better performance of webbing slings in operations. To maintain the safety of material and workers, inspect every sling on a regular basis.
