What effect does excessive abrasion have on a web sling?

• A. It increases the strength
• B. It can lead to sling failure
• C. It is generally harmless
• D. It enhances flexibility

Answer: (B)

Excessive abrasion on a web sling significantly compromises its integrity and functionality, making it a serious concern in safe rigging practices. When a sling experiences abrasion, it wears down the fibers of the webbing material, reducing its overall strength. This degradation can create weak points within the sling, which may ultimately lead to a complete failure during lifting operations.

It's essential to recognize that web slings are specifically designed to withstand certain loads and stresses; any factor that lowers their strength could result in catastrophic outcomes, including dropping a load or causing injury. Therefore, understanding the implications of abrasive wear is crucial for ensuring safety in lifting and rigging tasks.
