Which of the following best describes a precaution to take when loading heavy materials?

Ensuring that the load is balanced and within capacity is critical when loading heavy materials because it directly affects the safety and stability of the equipment as well as the load itself. A balanced load helps maintain proper center of gravity, which reduces the risk of tipping over during transport. Staying within the equipment's capacity prevents overloading, which can lead to mechanical failure, loss of control, or accidents.

Balancing the load also ensures that the weight is evenly distributed across the equipment, which is vital for safe operation. Uneven loads can cause the rear or front of the tractor-loader-backhoe to lift unexpectedly, leading to unwanted movements or even operator injuries. Thus, prioritizing balance and adherence to load capacity is essential in safe heavy material handling practices.
