What is an example of a passive fire protection system?

Passive fire protection systems are designed to contain fires or slow their spread without relying on active intervention. This can include methods like fire-resistive construction materials, which are specifically designed to withstand high temperatures and prevent the passage of fire and smoke. These materials can be found in walls, floors, and ceilings, creating barriers that help compartmentalize a building.

In contrast, active fire protection systems, such as fire alarms and sprinkler systems, require an action or intervention to function, like detecting smoke or deploying water to extinguish flames. Emergency exits also do not directly contain fires but rather provide a means for occupants to safely evacuate. Thus, fire-resistive construction materials are a quintessential example of passive fire protection because they serve to inherently protect the structure and its occupants without the need for any active mechanisms.
