An independent committee investigating Hong Kong’s deadly Tai Po blaze holds its 21st day of evidential hearings on Thursday, with three witnesses from the Urban Renewal Authority set to give evidence.

The tragedy at the Wang Fuk Court housing estate on November 26 last year claimed 168 lives and displaced nearly 5,000 residents.

The blaze broke out while the estate’s eight blocks were undergoing renovations. Flammable polyfoam boards used to seal household windows, along with allegedly non-fire-retardant scaffolding mesh, were identified as factors that contributed to the rapid spread of the fire.

On day 20 of the hearings, the Buildings Department told the judge-led panel that flammable polyfoam boards should not be used to block household windows due to the fire risks they posed, adding that their use was regulated by law.

However, the department said the Wang Fuk Court case did not fall within its remit, as it did not oversee government-built structures such as subsidised housing estates, which are regulated by the Independent Checking Unit (ICU) under the Housing Bureau.

A retired senior surveyor from the department also rejected the ICU’s claim that there were no regulations governing foam materials and said the unit had not consulted him before reaching that conclusion.

The committee also heard that, before the fire, the department had relied on certificates submitted by contractors to assess the fire retardancy of scaffolding mesh but had no mechanism to verify those documents.

The Home Affairs Department’s Tai Po district office liaison officer Or Wai-yin and then district officer Eunice Chan Hau-man were also questioned about the roles of the department and district councillor Peggy Wong Pik-kiu in decisions related to estate management and the HK$336 million (US$42.9 million) renovation project.
