Compartmentation Surveys & Passive Fire Barrier Verification

Compartmentation is the hidden system that helps stop fire, smoke, and hot gases from spreading through a building. It relies on fire-resisting walls, floors, and protected routes performing as intended—without unsealed penetrations and unknown breaches. Ignis Safety Consultants provides independent compartmentation surveys to help you verify the integrity of fire-resisting barriers and identify where remedial works are required. We act solely as consultants and advisors and do not install or supply fire stopping systems.

What compartmentation surveys help you achieve

In real buildings, compartment lines are frequently compromised by later works—cabling, pipework, ductwork, ceiling changes, and ad-hoc repairs. Professional guidance consistently emphasizes that penetrations and breaches must be properly sealed to maintain fire performance, and that selecting systems with suitable test/certification evidence is critical.

In Jersey, the Fire & Rescue Service also highlights compartmentation and fire stopping as key considerations in building safety review and advice.

What Your Receive

  • A written compartmentation survey report and findings summary
  • A prioritized schedule of issues (what is critical vs. what is improvement)
  • Photo-based evidence (where permitted) to support remedial planning
  • Clear recommendations that help you brief contractors and verify corrective works

What we review

  • Fire compartment walls and floors (as visible/accessible)
  • Service penetrations (cables, pipes, ducts) through fire-resisting elements
  • Ceiling void interfaces and barrier continuity (where access allows)
  • Protected corridors and stairs (as relevant)
  • Risers, plant rooms, and higher-risk zones
  • Evidence quality: whether works appear consistent and properly recorded
  • “Unknowns”: locations where verification is limited and further access is recommended

How we work

  • Define the scope: building areas, access method, and survey output format
  • Site survey: visual verification and targeted checks where possible
  • Record findings: identify likely compartment lines and notable breaches
  • Practical remedial guidance: identify suitable corrective actions and priorities
  • Optional support: toolbox talks and stakeholder briefings to reduce repeat defects and improve workmanship understanding

Where compartmentation surveys are commonly used

  • Existing buildings with unclear fire safety records
  • Buildings undergoing refurbishment or services upgrades
  • Higher-occupancy premises (care settings, education, multi-tenant buildings)
  • Buildings where insurers or governance teams require robust passive fire evidence
  • Projects where “as-built” compartmentation confidence is needed before sign-off
