Temporary Measures Have a Habit of Becoming Permanent

Walk around enough buildings and you'll find them everywhere.

A fire door held together with a "temporary" repair. A compartmentation defect protected by an interim management procedure. A fire alarm variation introduced during refurbishment. A waking watch that was only ever meant to bridge a short period of uncertainty.

Most temporary measures begin with good intentions. They are often sensible responses to emerging information, operational constraints or the practical realities of construction and remediation. The problem arises when the temporary measure outlives the circumstances that justified it.

Over time, familiarity breeds acceptance. Staff change. Project teams move on. Documentation becomes harder to find. What began as an interim control gradually becomes part of the normal operation of the building. The original risk remains, but the urgency to resolve it diminishes.

This presents a challenge for those responsible for fire safety. Temporary measures are often assessed against a clear objective: to maintain an acceptable level of safety until a permanent solution can be implemented. They are not normally intended to provide a long-term substitute for that solution.

The distinction matters. Interim arrangements frequently depend upon management actions, staff vigilance or procedural controls. Permanent solutions are generally more robust because they are less reliant on human intervention. A waking watch may compensate for the absence of a detection system, but it is not equivalent to one. A management procedure may reduce the consequences of a compartmentation defect, but it does not restore the compartment.

When reviewing fire risk assessments, fire strategies or remediation programmes, one useful question is simply:

"What was supposed to happen next?"

If nobody can answer that question, the temporary measure may already have become permanent.

The lesson is not that temporary measures should be avoided. Many are entirely appropriate and necessary. Rather, they should be accompanied by a clear exit strategy, defined ownership and periodic review. Otherwise, there is a risk that an interim control quietly evolves into the accepted condition of the building.

And that is rarely what was intended.
