A fire simulation investigating last November’s devastating Tai Po apartment complex fire, which resulted in 168 fatalities and displaced thousands, has identified substandard scaffold netting as a key factor in the blaze’s rapid spread. The simulation revealed that the use of non-fire-retardant materials in the scaffolding likely caused “secondary ignitions,” intensifying the fire. Testimony at a public inquiry detailed these findings, suggesting the netting contributed significantly to the inferno’s escalation. Investigators are examining how the flammable materials allowed the fire to quickly engulf the building’s exterior. The hearing aims to determine the precise cause of the disaster and prevent similar tragedies. The findings raise questions about building safety regulations and material standards in Hong Kong. Further investigation will focus on enforcement of fire safety protocols for construction sites.
