Is it permissible to carry a load using one fork arm? Why?

Carrying a load using one fork arm is not permissible because it significantly compromises the stability of the forklift. When a load is supported by only one fork, the center of gravity is displaced, increasing the risk of tipping or rolling over. This is particularly dangerous in a workplace environment where uneven surfaces or other factors might already affect the balance of the vehicle. Additionally, applying a load to a single fork can lead to damage to the forklift's arms as they are designed to distribute weight evenly across both fork arms. This improper usage can lead to premature wear, increased maintenance costs, and potential safety hazards for the operator and surrounding personnel. Therefore, adhering to proper load handling guidelines is essential for safe operation.
