Passive Fire Learning
Common Passive Fire Defects
Understanding common passive fire defects identified throughout commercial buildings during inspections and compartmentation reviews.
Unsealed Service Penetrations
One of the most common passive fire defects involves unsealed or incorrectly sealed penetrations where pipes, cables or ducts pass through fire-rated walls and floors.
Damaged Fire-Rated Walls
Damage to fire-rated plasterboard systems, missing linings or unapproved modifications can compromise compartmentation performance.
Fire Door Defects
Missing smoke seals, excessive door gaps, damaged hardware and wedged-open fire doors are common issues identified during inspections.
Incorrect Fire Stopping Systems
Passive fire systems should match tested system requirements including substrate type, service type and fire-rating requirements.
