What is the minimum headroom required over any walking surface for protruding objects to be permitted?

The minimum headroom required over any walking surface for protruding objects to be permitted is 80 inches. This standard is in place to ensure safety and accessibility, particularly for individuals who may be taller or using mobility devices. The 80-inch requirement allows ample clearance for most people to walk comfortably without the risk of hitting their heads on protruding objects, thus reducing the potential for injuries.

In commercial settings, this measurement aims to create an environment that accommodates a diverse population, including those who may have different physical dimensions or abilities. Ensuring that there is adequate headroom helps maintain safe passageways and contributes to good design practices in public spaces.
