What is the primary purpose of a barricade?

The primary purpose of a barricade is to deter the passage of either persons or vehicles. Barricades are essential safety devices used to control access to a particular area, often in construction zones or during public events. By effectively blocking both pedestrians and vehicles, barricades help prevent accidents and maintain safety by directing traffic appropriately and protecting individuals from potential hazards in the surrounding environment. Their design and implementation are crucial in ensuring that areas that may pose risks are clearly marked and restricted, thus serving a key role in occupational safety and health standards.
