What are the minimum dimensions for a barricade if debris is dropped through a hole and no chute is present?

The minimum dimensions for a barricade designed to protect individuals from falling debris are established to ensure safety in construction areas. The chosen dimensions, which are 42 inches in height and a minimum of 6 feet in length, serve to effectively shield workers and bystanders from falling objects when no chute is present to direct debris away from the work area.

A barricade that is 42 inches high is sufficient to deter accidental entry and to provide a clear visual indicator of the hazard area. The length of at least 6 feet helps ensure that the barricade effectively encloses a larger area, reducing the risk of injury from debris falling outside the immediate work zone.

In safety regulations, these specific measurements reflect the consensus on the necessary height and width for effective protection without requiring a chute, emphasizing worker safety and preventing accidents.
