Which of the following can improve overall safety during crane operations?

Regular training and communication of signals significantly enhance safety during crane operations. Training ensures that operators are familiar with the equipment, understand safety protocols, and are up to date on the best practices for operating cranes. This knowledge is crucial for effective decision-making and reducing the likelihood of accidents.

Effective communication of signals is equally important, as it allows coordination between the operator and ground personnel, minimizing misinterpretations that could lead to dangerous situations. Clear, systematic signaling promotes a safe environment since it helps everyone involved in the operation to be aware of each other's actions and intentions, ultimately contributing to safer and more efficient crane operations.

In contrast, while frequent breaks for the operator can mitigate fatigue, they do not directly address all safety aspects of crane operation. Using smaller cranes for heavy loads could compromise stability and safety, as cranes are designed to handle specific load capacities. Lastly, maximizing load capacity at all times can lead to overloading, which is a primary risk factor for crane accidents.
