Where are the highest number of non-fatal falls most likely to occur at a job site?

The highest number of non-fatal falls at a job site is most likely to occur from ladders. Ladders are commonly used in construction but are often subject to misuse or improper setup, leading to accidents. Many workers may not adhere to safe practices, such as ensuring that ladders are stable and not overloaded. Additionally, ladders can be used for various tasks, increasing their exposure to potential fall incidents. The frequency of ladder use combined with potential safety lapses contributes significantly to the occurrence of falls from this equipment.

In contrast, while scaffolding, stairs, and elevators can also be sources of falls, the extensive use and varied conditions encountered with ladders in many work environments typically lead to a greater incidence of non-fatal falls.
