One of the recurring themes emerging across fire safety investigations is that significant problems often develop at organisational boundaries rather than within a single discipline.

Many fire safety failures do not begin with a dramatic technical fault. They begin gradually, through assumptions about maintenance, ownership and long-term management.

A recent Swedish LinkedIn post caught my attention. It reports that two SP Fire 105 façade tests have been carried out at RISE in Borås on aged fire-retardant-treated timber façade panels.

Hazardous area classification is often seen as the defining feature of a DSEAR assessment. Zones, drawings, and equipment ratings quickly become the focus.

But zoning is not the starting point. It is the outcome.

DSEAR is often treated as a specialist add-on. Something required for high-hazard industrial sites, fuel depots, or chemical plants.

That is not what the regulations say.

Fire safety is often treated as a technical layer, something applied once the architecture is fixed. By that point, the most important decisions have already been made.

Third-party certification is widely relied upon in fire safety. It is often treated as a proxy for competence, quality, and compliance.

Cladding fire performance is often discussed in terms of the outer surface. Reaction-to-fire classifications and panel materials tend to dominate both specification and debate. That focus is understandable, but it is only part of the picture.

Recent work by MacLeod, Butterworth and Law provides a more complete view. Their parallel panel experiments examine cladding and insulation in combination, allowing the contribution of each to overall heat release to be measured.

Across engineering and scientific disciplines, the limiting factor is rarely the absence of knowledge. Advances in modelling, data analysis and material science continue at pace. The challenge lies in how that knowledge is interpreted and applied in practice.

Fire safety is no exception.

Investigators are working to establish how and why the New Year’s Eve fire at a bar in a Swiss ski resort developed so rapidly. Early indications point to a familiar combination: a small ignition source associated with a celebration, combustible lining materials, and a crowded internal environment.

There is a subtle but important shift underway in professional practice. It is not about new standards or new materials. It is about how decisions are being made, and more importantly, who is making them.

If a fire test is not a truth, then what happens when there is no test at all?

There is a persistent misunderstanding in fire safety that continues to surface in projects, reports, and, increasingly, disputes.

A reflection on ARB’s latest guidance, and the gap that still remains for architects

There is a quiet but dangerous assumption that crops up time and again in existing buildings: if a wall looks lightweight, it must be non-loadbearing. And if it is non-loadbearing, its fire rating can probably be reduced without consequence.

Positive Input Ventilation (PIV) has become something of a quiet success story in housing. It is simple, relatively cheap, and often effective at tackling condensation and mould by introducing a continuous supply of fresh, filtered air into a dwelling and displacing moist air.

A BBC story featuring a disabled teenager campaigning for legal change on evacuation planning should make uncomfortable reading for anyone involved in fire safety design.

There is a quiet shift underway in fire engineering. It is not about new guidance, new tools or even new regulation. It is about something less comfortable: whether the profession is prepared to learn in public.

Fire safety design continues to be framed, in many projects, almost exclusively around life safety. This is entirely appropriate as a minimum objective. It is not sufficient as a sole objective.

The industry has, understandably, leaned heavily into certification over the past decade. Third-party schemes, registers, accreditations and badges have all become more visible, more structured, and more frequently demanded. This is, in principle, a positive development.
