Hong Kong fire: Better public education on emergencies needed, says housing researcher

Key Concepts

• Scaffolding Materials: Bamboo, metal, mesh, safety nets.
• Fire Retardancy: Materials that are slow to ignite and burn slowly.
• Construction Standards: Regulations and codes governing renovation and building practices.
• Accountability: Holding individuals and companies responsible for safety failures.
• Supervisory Role: The responsibility of consultants in overseeing construction projects.
• Housing Management: The systems and bodies responsible for maintaining residential buildings.
• Emergency Preparedness: Training and education for residents on how to respond to emergencies.

Hong Kong's Deadliest Fire: Scrutiny on Construction Standards and Accountability

A devastating fire in Hong Kong, the deadliest in decades, has ignited intense scrutiny on the city's construction standards and raised critical questions about accountability. The blaze originated on the external scaffolding of one of the towers in the Wong Folk Court complex in the Taipo district, rapidly engulfing seven of the eight residential buildings. These blocks had been undergoing renovations since July of the previous year, encased in bamboo scaffolding and mesh.

Scaffolding Materials: The Bamboo Debate

For many years, bamboo has been the preferred scaffolding material in Hong Kong due to its affordability, abundance, and flexibility. However, this recent fire has intensified a pre-existing debate regarding its continued use. In March, Hong Kong officials had already mandated that 50% of new public works contracts must incorporate metal scaffolding.

The ongoing investigation is examining whether the construction materials used in the renovation adhered to safety standards. One expert suggested that the bamboo scaffolding might have acted as a conduit for flames to spread vertically. Conversely, others argue that bamboo is naturally slow to ignite due to its moisture content.

Focus Shifts to Mesh and Flammable Materials

Attention has also shifted to the mesh encasing the buildings. Any covering material is required to be fire retardant, meaning it should be slow to ignite and burn slowly to prevent rapid flame spread during a fire. Authorities are also investigating highly flammable styrofoam boards discovered outside the windows of multiple apartments.

Impact on Residents and Housing Shortage

As investigators meticulously sift through the debris to determine the cause of the fire, the undeniable reality is that hundreds, if not thousands, of residents have lost their homes in a city already struggling with a severe housing shortage.

Expert Analysis: Professor Yao Yang

Professor Yao Yang, Professor and Associate Dean from the School of Graduate Studies at Lingnan University, provided insights into the fire's contributing factors.

Potential Causes and Contributing Factors

Professor Yao identified several factors contributing to the significant fire. While some attribute the blaze to the use of bamboo scaffolding, he suggested that the green safety mesh or net used to cover the scaffolding might have been a more significant factor. He observed from news reports and social media that the fire spread rapidly along the mesh rather than the bamboo itself. Therefore, he emphasized the need for the government and public authorities to investigate whether the material used for the safety net met approved standards.

Company and Consultant Accountability

Professor Yao highlighted that if investigations reveal that the contractor failed to adhere to the "cooper practice" (likely referring to a code of practice) for scaffolding, which now clearly mandates the use of non-combustible materials for scaffolding, including safety nets and mesh, then the contractor should be held liable.

He further explained the role of an engineering consultant in renovations of this nature. The consultant typically acts as a supervisor, overseeing the contractors' work and ensuring compliance with laws and legislative requirements. This supervisory role makes the consultant significantly important in ensuring adherence to regulations.

Subsidized Home Ownership Scheme Housing

The Wong Folk Court complex falls under the subsidized home ownership scheme, constructed by Hong Kong authorities for sale rather than rental. Professor Yao noted that the management of such housing is similar to private housing in Hong Kong, involving owners' corporations and private property management companies. He did not foresee significant urgency or room for tightening controls on the management of this particular type of subsidized housing due to this incident.

Emergency Preparedness and Education

Professor Yao stressed the importance of proper education in emergency preparedness, particularly for the elderly and domestic helpers. He suggested that the government should do more to teach residents, especially the elderly who may be trapped, what to do in case of emergencies like fires. He also pointed out that domestic helpers, many of whom come from countries with fewer high-rise buildings, may not be fully aware of the specific procedures required in a high-rise context.

Conclusion and Key Takeaways

The fire at Wong Folk Court has exposed critical vulnerabilities in Hong Kong's construction and renovation practices. The investigation's focus on the fire retardancy of materials, particularly the safety mesh, and the adherence to updated codes of practice is crucial. The incident underscores the importance of robust oversight by consultants and the need for clear accountability for contractors. Furthermore, it highlights a pressing need for enhanced emergency preparedness education for all residents, especially vulnerable groups like the elderly, to mitigate the impact of future incidents. The event also exacerbates the existing housing crisis, leaving many displaced.
