Which of the following scenarios emphasizes the importance of planning in lifting operations?

Lifting over a public roadway highlights the crucial importance of planning in lifting operations due to the inherent risks involved. Operations conducted in such environments necessitate thorough planning to ensure the safety of not only the personnel involved but also the general public. This includes assessing the potential hazards that could arise, such as falling loads or equipment failure that may impact the roadway below.

Effective planning would involve implementing safety measures such as traffic control, signals for communication, and potentially coordinating with local authorities to ensure that the area is secured. Additionally, it requires identifying factors like the load path, rigging configurations, and environmental conditions that could affect the lift's safety and effectiveness.

In contrast, while lifting in an open field or on a rainy day presents challenges, and inexperienced personnel require supervision and training, the specific complexities and increased risks associated with lifting over a public roadway make detailed planning even more critical in that scenario.
