What must be done before moving the ladder at any point?

When moving a ladder, it is crucial to walk your path in order to ensure that the area is clear of obstacles and hazards. This helps to prevent accidents and ensures that the ladder can be positioned safely and securely. By being aware of the surrounding environment, one can avoid tripping over items, encountering uneven surfaces, or facing other dangers that could lead to falls or instability. This practice emphasizes the importance of situational awareness when handling equipment.

The other options, while important in their own contexts, do not specifically address the immediate requirement of ensuring a safe path for movement. Inspecting the ladder is essential before use, calling for assistance may be necessary in certain situations, and ensuring weather safety is critical during adverse conditions, but the first step before moving is to ensure that the path is clear.
