Passive Fire Protection (PFP) refers to building design features that help contain fires and prevent their spread without the need for active systems like sprinklers. This includes materials and construction methods that resist fire, such as fire-rated walls, floors, and doors. PFP aims to protect lives and property by slowing down the fire's progress and providing safe escape routes. Key components of PFP include fire-resistant materials, compartmentalization, and fire barriers. These elements work together to create safe zones within a building, allowing occupants more time to evacuate and emergency responders to manage the situation effectively.
