Fire Separation Penetrations Explained
Fire separation penetrations occur when services pass through walls or floors that are intended to resist the spread of fire and smoke.
BAKKER PFI shares practical guidance to help building owners, managers and project teams understand passive fire work more clearly.
Article overview
A fire separation only works properly if penetrations through it are treated correctly. Pipes, cables and trays can all compromise a rated element if openings are left untreated or poorly sealed.
What is a fire separation?
A fire separation is a wall, floor or other building element intended to limit the spread of fire and smoke between spaces for a defined period.
How penetrations affect it
Once services pass through a fire separation, the opening around those services needs suitable passive fire treatment or the separation may no longer perform as intended.
Typical locations
Common locations include risers, service shafts, apartment walls, corridor walls, plant rooms and floor penetrations between levels.
Why records matter
Documented passive fire work makes future maintenance and inspections much easier, especially where penetrations may later be hidden from view.
