Which of the following is a best practice for rigging?

Using multiple attachment points for balance is indeed a best practice for rigging because it distributes the load evenly, reducing the risk of equipment failure and enhancing safety. This technique helps to prevent undue stress on any single point, which could lead to accidents or damage to the materials being lifted. When the load is balanced, it improves stability during the lift and allows for better control, making the operation safer for everyone involved.

In contrast, relying on a single point or the minimum rated capacity can lead to significant risks, as these approaches do not adequately account for unexpected shifts in weight distribution or additional forces that may come into play during a lift. Working without a partner increases hazards, as it can compromise safety and situational awareness. Ignoring environmental conditions puts the entire operation at risk, as factors such as wind, rain, or uneven ground can drastically affect rigging operations. Hence, employing multiple attachment points provides a more secure and effective means of rigging and lifting.
