Which of the following describes a "Passive Fire Protection System"?

A system requiring active control to prevent fire
A fire suppression system activated by smoke
Any portion of a building that protects from fire without activation
A system that alerts occupants during a fire

The correct answer is: Any portion of a building that protects from fire without activation

A "Passive Fire Protection System" refers to components that are built into a structure to enhance its fire-resistance and prevent the spread of fire without requiring any activation or action from individuals. This includes elements such as fire-resistance-rated walls, floors, and ceilings that compartmentalize areas, and fireproof doors that help contain blazes and smoke. These systems are designed to slow the spread of fire and allow occupants more time to evacuate, as well as enhance the safety of emergency responders. While other options involve systems or components that require some form of action or activation, such as alerting occupants or suppressing a fire, the essence of passive fire protection lies in its inherent characteristics that operate without external influence, thereby providing continuous safety and fire control measures.
