Hong Kong Fire Inquiry: Experts to Testify on Blaze's Rapid Spread

As a judge-led panel continues its public inquiry into Hong Kong’s deadliest fire in decades, experts are set to give evidence on factors that contributed to the rapid spread of the blaze.

Richard Yuen Kwok-kit, chair professor of architectural engineering at the City University, will testify on Wednesday before the independent committee regarding the fire at Wang Fuk Court in Tai Po. He was appointed by the government as a fire engineering expert.

Following him will be two witnesses from the Fire Services Department: Dr To Chi-wing, the divisional commander for the airport, and Yiu Men-yeung, assistant director for New Territories South, who is also head of the government’s interdepartmental investigation task force.

The panel, led by Justice David Lok Kai-hong, has also appointed two professors from Polytechnic University as independent experts.

The fire broke out on November 26, 2025, while the residential estate was undergoing a major renovation. It burned for more than 43 hours, claiming 168 lives and displacing nearly 5,000 residents, making it the city’s worst blaze since 1948.

At a previous session on Monday, Lok said the panel would not seek to upgrade its status to a statutory commission of inquiry with powers to summon witnesses.

He explained that doing so could delay the process by years and hinder the timely release of a final report needed to support legal proceedings and reforms.

While such powers could compel testimony, he added, they would not necessarily ensure full cooperation from witnesses.

Monday’s session also heard from Lam Kin-kwan, deputy head of the government’s interdepartmental investigative task force, and Dr Lee Wing-man, chief chemist in drugs and toxicology at the Government Laboratory.

Lam said the fire spread “geometrically” in its early stages and noted that earlier emergency calls and a faster response could have been critical in limiting its escalation.

Lee confirmed that the fire originated in the light well outside units 104 and 105 at Wang Cheong House, with a discarded lit cigarette believed to be the most likely cause.

Laboratory tests also found that materials used at the renovation site – including scaffolding mesh, polyfoam boards and plastic sheets – were not fire-retardant.

She further noted that temporary access openings, covered with wooden or aluminium composite boards in place of fire-rated windows on emergency staircases, allowed toxic smoke and flames to enter the stairwell.
