In Group E occupancies, which typically include educational facilities, the International Fire Code has specific regulations regarding the use of wall space in corridors to ensure that egress pathways remain safe and unobstructed. The correct maximum percentage of wall space that can be occupied by artwork in these corridors is 20%. This regulation is put in place to minimize potential hazards in case of an emergency evacuation, maintaining the necessary visibility and accessibility of egress routes.

The limitation is designed to prevent excessive obstructions and ensure that artworks do not contribute to the spread of fire or impede the movement of individuals in case of an emergency. The standards for wall space occupancy consider both aesthetic value and safety, which is why the percentage is capped at this level.

In contrast, higher percentages like 30% or 50% would pose increased risks by potentially overcrowding the corridor walls, reducing escape options and complicating evacuation efforts. A lower percentage like 10% might be too restrictive, as it does not allow for sufficient expression of educational and artistic values within the environment. Thus, 20% strikes a balance between maintaining safety and allowing for some degree of decoration within the corridors of Group E occupancies.
