Which of the following heights would be considered inappropriate for barriers in an assembly setting?

In an assembly setting, barriers serve specific functions such as crowd control, safety, and delineation of areas. A height of 5 feet for barriers would generally be considered inappropriate because it may obstruct visibility, impair emergency egress, and hinder effective communication among safety personnel and attendees. Barriers that are too high can create a sense of confinement and discourage free movement, which could lead to panic in case of emergencies.

Lower heights, such as 2 feet, 3 feet, or 4 feet, are much more acceptable as they provide a clear line of sight, allow for easy interaction, and foster a safe environment while still maintaining a level of physical separation or control over the crowd. Thus, a barrier height of 5 feet does not align with the best practices for safety and crowd management in an assembly space.
