What is a common cause of rigging failure?

Overloading or improper attachment to the load is a critical factor that can lead to rigging failure. When loads exceed the safe working load limits of rigging equipment, the inherent stress can lead to catastrophic failures. Ropes, shackles, and other equipment might not be capable of handling the excessive weight, resulting in structural failure, snapping, or accidents that can cause injuries or damage. Proper attachment ensures that the load is balanced and distributed correctly, reducing the risk of failure during operation. Understanding load limits and ensuring proper attachment techniques are essential components of safe rigging practices.

While the other options point to relevant safety concerns, they typically do not have as direct an impact on the immediate risk of failure as overload does. Color coding, outdated equipment, and inadequate training are important factors to monitor, but they usually serve as preventative measures rather than direct causes of failure during a lifting operation.
