Across every service · Evidence gap
What if the installed passive fire system cannot be identified?
Treat a missing identity as an evidence problem rather than a workmanship one. Collect labels, product markings, drawings, schedules, photographs and the geometry of the opening. If the system still cannot be established, do not close the issue by naming the most likely product.
What changes the answer
- Whether anything is physically on the installation — a tag, a stencil, a stamped date, a batch mark, or a sealant colour that is characteristic of one system.
- Whether the building holds the handover pack, the asset register or the original contractor’s certificates for that area.
- How old the installation is. The older it is, the less likely a record exists and the more likely the material itself has to be established before anything else.
- Whether the element can be seen from both faces. One face tells you half the story, and the half you cannot see is usually the half that decides it.
- Whether the same condition repeats across the building. A repeated detail is normally one system installed by one contractor, and resolving it once resolves all of them.
- Whether anything has been added, disturbed or re-sealed since. A penetration that has been opened and patched is no longer the thing that was tested, whatever the tag says.
What to check on site
- Photograph it at context scale and close up, including any writing on it, before anything is touched or cleaned.
- Look for a tag, stencil, stamp or label on both faces of the element and on the structure beside it, not only on the seal.
- Record the opening dimensions, the substrate, what passes through and the annular space. Geometry often narrows the field to two or three systems.
- Check the asset register, the handover pack and the last inspection report against the same location reference.
- Ask the building who did the work. A contractor name is frequently enough to find the system when the tag is gone.
- Treat anything that may predate 1990 as possible asbestos-containing: record it, do not probe it, and resolve that question before the passive fire one.
What to do next
Send the photographs, the location reference and whatever records the building holds. We will tell you what can be established from them, what cannot, and whether the honest answer is a records search, a site verification, or a system that has to be replaced because its identity can never be proven.
General information only. A conclusion about a specific condition requires the actual construction, the evidence behind it and the site condition to be reviewed.
