According to safety regulations, what must be the maximum height of any vertical signs in shopping malls?

The maximum height for vertical signs in shopping malls is determined by safety regulations to ensure visibility and accessibility for all patrons, including those with disabilities. A height of 96 inches allows signs to be positioned above the heads of adults while still being visible to individuals in wheelchairs or using mobility devices. This regulation helps create an inclusive environment, ensuring that all customers can easily locate stores and navigate the space without obstructions.

The other options represent heights that may not adequately balance safety and visibility; for example, a height of 48 or 60 inches could be too low, potentially obstructing sightlines and creating hazards in busy walking areas. Meanwhile, a height of 72 inches, while somewhat acceptable, still might not fully meet the accessibility requirements for taller individuals or specifically designed mobility aids. Thus, the 96-inch standard is set to maximize effectiveness while prioritizing safety for everyone in the shopping environment.
