In terms of fire safety, what is the meaning of "passive fire protection"?

Passive fire protection refers to the inherent features of a building that are designed to contain or slow the spread of fire without the need for active human involvement. This includes structural components like fire-resistant walls, floors, and doors, as well as materials that can withstand high temperatures and inhibit flames from spreading throughout a facility. The goal of passive fire protection is to create barriers that help protect occupants and property during a fire event, allowing additional time for evacuation and emergency response without requiring active management or intervention by employees.

In contrast, other options refer to systems or measures that involve active participation or ongoing training, which are not characteristics of passive fire protection. The nature of passive fire protection relies on the building's design and construction rather than on human activity or monitoring.
