What must be done to prevent injuries when debris is being dropped at a worksite?

To effectively prevent injuries when debris is being dropped at a worksite, enclosing the work area with barricades is crucial. This method creates a physical barrier that restricts access to the potentially hazardous zone, thereby safeguarding employees and passersby from falling objects. Barricades help in visually and physically controlling the area, ensuring that only authorized personnel are present and reducing the risk of accidents.

Utilizing proper signage is important as well, as it communicates the danger to workers and visitors. However, signage alone does not provide a physical safeguard, which is why it is not as effective as barricading the work area. While wearing safety goggles protects individual workers from potential eye injuries caused by flying debris, it does not prevent the overall risk of someone being hit by falling materials. The monitoring of the area by supervisors is also essential for safety checks and compliance but does not establish a protective measure against falling debris. Therefore, enclosing the area with barricades is the most effective approach to prevent injuries associated with debris being dropped.
