What is the vital reason for avoiding the loading of heavy materials on sloped areas?

Loading heavy materials on sloped areas poses significant hazards to safety due to the risk of equipment instability and the potential for accidents. When heavy loads are positioned on an incline, the center of gravity of the machinery may shift, increasing the likelihood of tipping or rolling over, especially if the load is unevenly distributed or if the slope is too steep. Operators must prioritize safety to prevent incidents that could result in injury to personnel or damage to equipment and property. Ensuring that loading activities occur on stable, flat ground minimizes these risks. The other options do not adequately capture the critical safety concerns associated with this practice.
