What is passive fire protection?
Time that saves lives.
Passive fire protection refers to the built-in structural measures that help slow or prevent the spread of fire and smoke within a building.
Unlike active systems such as alarms or sprinklers, passive fire protection does not activate – it performs continuously as part of the building’s fabric.
- Maintain compartmentation
- Protect escape routes
- Reduce smoke spread
- Support structural fire resistance
- Buy critical time for evacuation
