Advantages and Disadvantages of Synthetic Slings

Q: Should I use paint or dye to color code synthetic slings?
No. Avoid using paint to color code webbing slings—the solvents in the paint could corrode the synthetic material. A torn or broken sling is unsafe, and will drastically reduce its SWL. To identify a synthetic sling’s material, look for the label color:

• Polyester (PES)—Blue Label, or blue with a green line down the center of the webbing.
• Polyamide (PA)—Green label
• Polypropylene (PP)—Brown label

Q: What markings should I look for on a synthetic sling?
Look for the safe working load (SWL), identification number, and the label’s color code. Need more technical information on working load limits? You may need to refer to the relevant Australian Standard.

Q: How should I store my synthetic sling?
Store your slings in a dry, cool place. Keep them out of sunlight or other ultraviolet radiation, and don’t store them in damp conditions.

Q: Can I tie a knot in a synthetic sling to make it shorter?
No! Never knot, tie, or twist a webbing sling. Don’t manipulate the sling’s angle, either—use the sling however the angle forms naturally.

Q: What should I keep in mind when using a synthetic sling?
There are a few things to consider to use a synthetic sling safely—you should always: avoid shock-loading; protect the sling with sleeves when sharp edges could tear its fabric—friction can cause heat damage, which is the most common form of ‘heat’ damage to webbing slings. To prevent, don’t let the sling run along the load’s surface and that it’s not pulled on any sharp corners. This is also known as ‘point loading’, when the load is pulled on a sharp corner, creating heat which results in heat fusion in the sling material.
