What is the minimum height for drums used in work zones?

The minimum height for drums used in work zones is set at 36 inches. This height is established to ensure that the drums are visible to both drivers and pedestrians, effectively providing guidance and warning of the work zone ahead. The visibility height plays a critical role in enhancing safety by reducing the likelihood of accidents in construction or maintenance areas. Drums that are too short may not be easily seen, especially by larger vehicles, which could lead to confusion or unsafe driving behaviors. Therefore, adhering to the standard height of 36 inches ensures that the drums function effectively as part of the overall traffic control plan in a work zone.
