When plumbing, HVAC, sprinkler, or electrical pipes pass through a fire-rated wall, floor, or ceiling, they create an opening in the building’s fire protection. Under the BC Building Code, every one of those penetrations must be sealed with an approved fire stopping system to restore the fire-resistance rating of the assembly. Here is what building owners, contractors, and strata managers in BC need to know.
What Is Fire Stopping?
Fire stopping (firestopping) is the sealing of openings and joints in fire-rated assemblies using tested materials — firestop caulks, putties, pillows, collars, and wraps — so that fire, smoke, and hot gases cannot pass through. Each installation must match a tested system listing for the specific pipe material, size, and wall or floor type.
Why Fire Stopping Is Mandatory Around Pipe Penetrations
Fire-rated walls and floors are designed to contain a fire for a rated period — typically 1 or 2 hours — giving occupants time to escape. An unsealed pipe penetration breaks that barrier: in a fire, flames and toxic smoke travel through the gaps around pipes into neighbouring suites, corridors, and floors within minutes. That is why the BC Building Code requires penetrations through fire separations to be sealed with a listed firestop system that maintains the rating.
Where Fire Stopping Is Required
Common locations in Vancouver and BC buildings include:
- Pipes passing through walls between residential suites
- Plumbing and HVAC risers in vertical shafts
- Sprinkler and mechanical penetrations through parkade ceilings
- Electrical and data conduits through fire-rated corridors and stairwells
What Happens Without Proper Fire Stopping?
Failed inspections and occupancy delays are the most immediate consequence — building inspectors in BC check firestop installations closely. Beyond that, unsealed penetrations create serious liability: in the event of a fire, insurance claims can be affected and building owners may be held responsible for non-compliant work. Most importantly, lives are at risk when smoke spreads unchecked.
