What is an essential feature in the design of a building that promotes passive fire protection?

An essential feature in the design of a building that promotes passive fire protection is the use of fire-resistant materials in construction. These materials are integral to the overall fire safety strategy because they help contain a fire and prevent it from spreading through the building. By incorporating fire-resistant walls, floors, and ceilings, the structural integrity is maintained longer during a fire event, allowing for more time for occupants to evacuate and for firefighters to respond.

Passive fire protection is about using building materials and designs that inherently resist fire without the need for active systems, such as sprinklers or alarms. The choice of appropriate fire-resistant materials can significantly reduce the risk of fire escalation and provide crucial barriers between different areas of a building, leading to enhanced occupant safety and protection of property.
