27th November 2025 – (Hong Kong) The images out of Tai Po this week are difficult to shake i.e. entire towers of Wang Fuk Court shrouded in scaffolding and green mesh, flames racing up 31 storeys in minutes, smoke blotting out the afternoon sky. The death toll has climbed with grim regularity, and with it the certainty that this was not simply a horrific accident. It was a preventable catastrophe, accelerated by a culture of cheap, combustible temporary works that has persisted long after the lessons of other high-rise infernos should have been absorbed.
Bamboo scaffolding is an emblem of Hong Kong’s skyline—ingenious, light, quick to erect, and forged through decades of craft. It is also, by its nature, fuel. That truth has been documented repeatedly by safety authorities. From 2018 to early 2025, at least 23 deaths were linked to bamboo scaffold incidents. The Development Bureau itself acknowledges bamboo’s inherent weaknesses: variability in strength, degradation with weather and time, and high combustibility. In March, the government moved—cautiously—to require metal scaffolding for at least half of new public works contracts. That partial shift came too late for Wang Fuk Court, where all eight 31‑storey blocks had been wrapped since last year in bamboo frames and protective netting while major façade works progressed.
Preliminary accounts from engineers and fire experts converge on a brutal sequence: exterior ignition on scaffolded elevations, rapid vertical spread along bamboo poles and plasticised mesh, wind‑driven embering, and re‑entry into flats through compromised apertures. One building expert noted that flames climbed the equivalent of 32 floors in about five minutes—far outpacing any realistic evacuation time in a structure of that height. Buildings are designed to contain ordinary compartment fires; few codes truly anticipate an external, scaffolding‑fed firestorm rebounding inward across multiple towers.
If bamboo is the accelerant, the fuel bed appears to have been deepened by the materials chosen for “temporary” protection. Fire Services officials have flagged the presence of highly flammable foam boards—polystyrene sheets—used to seal lift lobbies or window openings during chiselling and plaster spraying. Police now allege “gross negligence,” pointing to documents from a contractor specifying foam board coverings, tape and silicone layering across windows, with additional plywood or hollow board on the exterior during works. Such methods, if proven, would have created a deadly chimney i.e. a sealed interior vulnerable to heat build‑up and toxic smoke, coupled with an exterior sheath primed to burn and shed flaming debris.
None of this should have been possible under a rigorous safety regime. The Code of Practice for Bamboo Scaffolding Safety states plainly that nets, screens and sheeting must possess appropriate fire‑retardant properties. The Labour Department and Buildings Department both stress that scaffold protection and tarpaulins should be fire‑retardant. Yet “should” has too often meant optional in practice. Industry figures concede that fire‑retardant mesh typically costs substantially more than ordinary netting, with a similar differential between compliant coverings and cheaper alternatives. When specifications are advisory rather than mandatory—and when oversight on small, distributed renovation jobs is patchy—the market’s gravitational pull is towards the low‑cost, high‑risk choice.
This is not a hypothetical failure of policy. Safety professionals have warned for years that reliance on voluntary compliance invites corner‑cutting. One veteran safety adviser put it bluntly: if rules are not hard requirements, some will gamble. Add to that the everyday laxities of site culture—smoking on scaffolds, limited on‑site safety supervision at occupied refurbishments—and the result is a tinderbox draped around people’s homes.
Residents continued living in the estate while all eight blocks were scaffolded and netted, with works that reportedly included exterior plaster spraying and terrazzo finishes. The union representing bamboo scaffolders argues that allowing all blocks to be encased simultaneously was a structural error i.e. once one elevation is alight, “fire spreads like chained boats,” as one organiser put it. Staggered phasing, faster turnaround, and strict time limits on how long scaffolds can remain erected on occupied towers are not niceties; they are life‑safety measures. The argument that full‑estate wrapping speeds completion must now be weighed against the demonstrated risk of multi‑block propagation.
Some will say that this tragedy is an outlier—the freak confluence of weather, debris, wind and a single errant spark. That understates the systemic nature of the hazards. The external pathway that let flame leap from floor to floor is a known failure mode. The presence of combustible netting and foam is a controllable variable. The use of bamboo across contiguous façades is a design choice, not destiny. The idea that buildings are safe because their concrete cores are robust is comfort of the wrong sort when residents are trapped behind sealed openings and throttled stairwells while exterior flames are driven upward like a blowtorch.
Police have arrested two company directors and an engineering consultant on suspicion of manslaughter; investigators have reportedly seized documentation tied to protection methods and material selection. Due process will determine culpability, but the prosecutorial posture signals a recognition that “industry practice” is not a shield when practice is reckless.
All scaffold nets, tarpaulins and window protections should carry mandatory fire‑retardant certification with type approval, clear site labelling and random testing, while polystyrene and comparable foams must be barred from external façades of occupied buildings.
Hong Kong should also accelerate the retreat from bamboo on lived‑in high‑rises by converting March’s partial requirement into a definitive timetable that prioritises metal systems for residential refurbishments above specified heights or occupancies. Where bamboo cannot yet be dispensed with, scaffold layouts must include fire breaks and non‑combustible vertical barriers. Phasing and dwell time should be tightly controlled i.e. limit how many blocks in an estate may be wrapped at once, cap how long scaffolds can remain on an elevation, and demand explicit fire‑spread risk assessments before permits are granted.
Every occupied façade project must have a competent safety officer on site, empowered to enforce bans on smoking and hot works and to impose penalties that deter breaches. Finally, transparency should be built into the system i.e. publish contractors’ compliance records, require estates to display material specifications and certifications, and provide residents with a direct reporting channel that triggers inspections within strict timeframes.
The fire also reopens a debate that Hong Kong, like London after Grenfell, has preferred to postpone i.e. how we price safety in dense cities with vast stocks of ageing buildings. Fire‑retardant mesh, non‑combustible coverings and metal scaffolds cost more upfront. They cost less than funerals, rehousing and a community’s trust. Public funds often underpin refurbishment programmes; public policy should therefore stipulate the safest practicable methods and absorb the premium as part of the social contract.
