What is the minimum height and width for Type 1 barricades?

For Type 1 barricades, the minimum height is indeed set at 36 inches, which makes it visible enough for both pedestrians and vehicular traffic. Additionally, the barricade must have a single rail that is between 8 to 2 inches, ensuring that it is adequately structured to deter people from crossing into hazardous areas while also maintaining a balance of visibility and stability. The combination of the specified height and the corresponding rail dimensions allows the Type 1 barricades to serve effectively in various work zone settings, providing both safety and guidance.

This construction guideline serves to address critical safety concerns, which is fundamental in work zone environments where awareness of potential hazards is essential for the protection of workers and the public.
