What should be done when workers are exposed to a falling object?

When workers are exposed to a falling object, the most effective and immediate action is to prohibit employees from entering the barricaded area. This response ensures the safety of all workers by preventing potential injuries caused by falling objects. Proper barricading serves as a clear physical and visual warning that the area poses a risk, effectively minimizing the chance of accidents related to falling debris.

Although providing safety helmets is a valuable safety measure, it does not eliminate the risk associated with entering a hazardous area. Safety helmets can provide protection from minor impacts but do not prevent workers from being exposed to the hazard in the first place. Allowing access to the area contradicts the principle of maintaining a safe work environment where workers are shielded from identified risks. Notifying the supervisor is important, but it is not a comprehensive solution. Prohibiting access directly prevents exposure to the danger, making it the most effective immediate action.
