Why is "passive" fire protection necessary?

Fire is a dangerous enough phenomenon that redundancy in fire protection is necessary. Having passive protection in place helps assure building occupants that there will be time to exit before gasses, fire and smoke spread throughout the building. If active systems fail, as they often do, then there is still a passive system in place for life safety.

Typical Firestop Application

What is firestopping?

Firestopping is an integral part of fire protection engineering. Firestop systems protect against the passage of flames, deadly gases and toxic smoke through openings that are created for penetrations, joints and gaps in fire-resistive walls, floors and floor/ceiling assemblies. The integrity of fire-rated assemblies is restored by firestop systems. Building codes require third-party tested systems to be installed whenever fire-rated construction is compromised by such openings.

What is meant by "active" and "passive" fire protection?

Active fire suppression includes mechanical systems such as sprinklers, that are designed to extinguish fires after they have started. Passive fire protection functions to contain fires within the areas in which they start, preventing loss of life by preventing the products of combustion (smoke, hot gasses and flames) from spreading throughout a building.
