Which of the following would be categorized under "planning" when using the 4 Ps?

The correct choice revolves around the proactive assessment of resources and tools that can aid in a manual handling task, making it integral to the planning stage. Considering whether handling aids can be utilized is a key component of effective planning, as it involves evaluating what support mechanisms are available that could enhance safety and efficiency during lifting. By identifying and planning for the use of handling aids, individuals not only prepare for the physical demands of the task but also help to mitigate potential risks associated with manual handling.

In contrast, the other options pertain more to preparation or execution rather than planning. Checking if the path is clear is more about preparation for the task at hand, ensuring safety just before the lift occurs. Ensuring proper posture during the lift relates to the execution phase, focusing on how the lifting should be done. Assessing the weight of the load also plays a role in immediate preparation rather than long-term planning, as it informs the decision-making process right before a lift but does not involve strategic planning for the overall approach to manual handling tasks.
