The tragic Tai Po fire incident in Hong Kong, which resulted in more than a hundred casualties, has shaken the region — and the entire built environment community. The building was fully occupied while its façade was undergoing refurbishment and upgrading works.
Many people assume:
“External façade works are outside the building — how can they affect the safety inside? At most, it’s just about preventing falling debris.”
But the truth is, external works on a high-rise building can create far greater internal risks than most people realise.
When an entire tower is wrapped with full-height scaffolding and covered with combustible protective netting, it forms a massive vertical and horizontal fire pathway.
Once a fire starts on the outside, it can spread rapidly upward and sideways, then penetrate into the units through windows or openings.
While investigations are still ongoing, early reports suggest that several possible contributing factors may have intensified the fire spread and hindered evacuation:
⚠️ Use of protective netting below fire safety standards for the façade works
⚠️ Styrofoam boards used to cover windows — trapping heat, accelerating fire spread, and preventing occupants from seeing smoke or flames early, delaying their awareness and escape.
⚠️ Fire staircase windows used for material loading access — exposing the escape route to external fire risk and compromising the integrity of the fire escape path.
⚠️ Fire alarm systems malfunction or temporarily disabled to ease delivery through fire-rated lift lobby doors.
⚠️ Scaffolding erected around all blocks simultaneously — reducing fire separation between buildings and creating continuous fire channels.
These so-called “temporary measures” become deadly vulnerabilities during a fire.
When flames travel up the scaffold and protective netting, they can break into units from the outside — giving residents almost no time to react.
A staircase that should have been the safest escape route becomes compromised because opened windows allow smoke and fire to sweep in.
This is why external façade works can impose tremendous internal safety risks.
It is far from “just external work” — it can be the most overlooked yet critical threat in a lived-in building undergoing refurbishment.

A Wake-Up Call for the Entire Building Industry
The life safety of occupants must always be the prime consideration.
This tragedy pushes us — as part of the building industry — to re-examine our collective roles and responsibilities in safeguarding public safety.
Most of the time, our attention is focused on fire safety for new buildings or unoccupied spaces.
But incidents like this remind us that construction sites, especially those within lived-in buildings, pose significant risks that are often underestimated.
This incident reinforces several critical points:
🔸 Safety is a shared responsibility — no single party can ensure it alone; architects, contractors, engineers, building facility managers, and authorities must work hand-in-hand.
🔸 Integrity in tendering and construction matters — cost-cutting, shortcuts, or non-compliant methods can lead to catastrophic outcomes.
🔸 Construction-stage fire safety is often overlooked — temporary works, hoarding, scaffolding, blocked exits, and inadequate site safety control can all become deadly hazards.
🔸 Authorities also play a crucial role — through enforcement, inspections, and ensuring that approvals and site safety guidelines are properly implemented.
🔸 Lived-in refurbishment requires heightened caution and clear methodology — because people are still living, sleeping, and working inside these buildings every day.
As professionals in this industry, we must continuously remind ourselves:
Safety is not a checkbox. It is a culture.
And maintaining it requires vigilance, integrity, and proactive action from every party involved.
“Let this be a reminder that in everything we build, manage, or approve —
human lives must always come before profit or convenience.”
May the victims rest in peace.
