Our Nylon Lifting Slings and Straps are manufactured with a safety factor of 5 to 1. With this being said this factor is for when the sling is new. Over time the sling degrades, how quickly this happens depends on type of use, frequency of use, where it is used.

A Nylon Slings is degraded by the following dirt, cuts, wear, chemicals, overloading, stitching missing, sun light and weather issues and others.

Your Lifting Slings whether they are Chain Slings, Nylon Slings, wire ropes, or Poly Slings and straps should be keep clean and properly stored.

The frequency of inspection depends on three important factors:
1. Sling usage – the more you use a sling, the more you need to inspect it.
2. The working environment – the harsher the conditions, the more often you need to inspect.
3. Sling service life – based on your experience in using slings. It’s a good idea for the person handling the slings to  visually inspect all slings before each lift. Additional inspections should be performed at least annually by a qualified designated person and permanent records kept.
OSHA specifies, “Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a competent person designated by the employer. Additional inspections shall be performed during sling use, where service conditions warrant.” In other words, you should visually inspect your sling before each lift.

This is the case for any type of lifting sling. This includes the following, Nylon Slings, Polyester Slings,Web Slings ,grade 80 Chain Slings, Grade 100 Chain Slings, and wire rope.

All it takes is a little ordinary dirt, grit and grime to reduce the overall strength and life of your Synthetic Slings. It’s very easy for these contaminants to penetrate between fibers anytime the webbing bends, pulls tight against loads, or stretches and
relaxes during loading and unloading. Once in place, they grind against the fibers, reducing their strength and useful
life. That’s why it’s a good idea to properly store your Nylon Lifting Slings and Polyester Lifting Slings when they’re out of service and to clean them when they become soiled. When slings are clean, they’re not only easier to inspect, they’re also stronger and more durable. There are many procedures you can use to clean your slings, depending on how soiled they are. For everyday dirt and grime, you can clean with soap or detergent and water for good results. Whatever cleaning method you use, always hang your washed Slings in a dry, sheltered place. Always keep slings from prolonged contact with direct sunlight during drying and storage because ultraviolet rays can degrade synthetic fibers. Nylon or Polyester Slings that have been dyed any color but white will fade somewhat due to washing, but this in no way affects the strength of the webbing. Both Nylon Webbing and Polyester Webbing have an extremely low water absorption rate, making them flexible, light and easy to handle even after prolonged
soaking in water. Both also show excellent resistance to mold, mildew and fungus, although dirt that accumulates on slings may support their growth, and that’s why regular cleaning is very important.
