Compartmentation is one of the most fundamental principles in building fire safety.
The idea is straightforward: divide a building into sections that contain fire and smoke long enough for people to evacuate and for the fire service to respond.
In practice, maintaining compartmentation across a live building is more complex. Every service pe*******on through a fire-rated wall or floor is a potential breach. That means pipes, cables, ducts and conduits all need to be sealed to the correct standard using tested details appropriate to the service type, the substrate and the gap size.
When this is done correctly and documented properly, the compartmentation works as designed. When it is not, the integrity of the entire floor or zone can be compromised by a single unsealed pe*******on.
This is why the detail matters. Not just the installation, but the record of what was installed, where, and to what specification.
