When the vertical clearance is less than what height must a barrier be provided?

For vertical clearances that are less than 80 inches, a barrier must be provided to ensure safety and accessibility. This regulation is primarily in place to prevent unintended contact or head injuries, especially in areas where people may be walking or passing through. The requirement for a barrier at this height recognizes that individuals of varying heights, including children and those of shorter stature, may navigate these spaces.

Maintaining a clearance of at least 80 inches in commercial buildings helps to create an environment that minimizes risks associated with low overhead obstructions, allowing for safer movement and reducing liability for property owners. Adhering to this height is also consistent with the guidelines established by codes that govern commercial building construction and safety.
