The Warning from the Hongfu Yuan Fire in Hong Kong: A Tragedy Caused by the Failure of Three Key Fire Prevention Measures
Three lines of defenseThree lines of defense
On November 26,2025, a devastating fire erupted at Hongfu Garden in Tai Po, Hong Kong. As of December 9, the incident had claimed 160 lives, with approximately six people still missing. This deadliest fire disaster in Hong Kong in recent years has not only caused profound grief but also prompted deep reflection on building fire safety design. From a professional fire safety perspective, the tragedy exposed systemic failures in three critical aspects of fire protection design. Had any one of these three safeguards been effective, the severity of the tragedy could have been significantly mitigated or even entirely prevented.
The first line of defense: the ineffective fire barrier provided by exterior wall windows
◇ Preliminary fire investigation results indicate that flames rapidly spread through exterior window openings into the interior, serving as a key factor in the fire's out-of-control progression. In modern high-rise building fire protection design, windows function not merely as lighting and ventilation components but also as critical elements of fire compartments. Fire-resistant windows, as specialized fire safety products, maintain their fire resistance integrity for a specified duration, effectively delaying flame propagation from both external and internal sources.
However, many units in Hongfu Yuan are equipped with ordinary glass windows, which rupture rapidly under high temperatures, providing a pathway for flames to enter the interior. Once the exterior windows lose their fire-resistant function, the entire building becomes akin to a well-ventilated furnace, with the fire spreading rapidly between floors and creating what is known as the "chimney effect."
If the exterior windows of Hongfu Yuan are equipped with fire-resistant windows that meet standard specifications, the fire can be contained within the initially affected unit or localized area, providing crucial time for evacuation and firefighting efforts. This has been demonstrated in numerous successful fire incidents both domestically and internationally: when a building's external envelope possesses adequate fire resistance, the fire is typically confined to a limited scope.
The second line of defense: the lack of indoor fire safety shelters.
◇ In residential fire safety design, the concept of a "refuge room" is crucial. Ideally, each residential unit should have at least one room whose doors consist of fire-resistant materials and walls, creating a relatively safe refuge space. When the entrance door is blocked by flames, residents can retreat to this room and await rescue; such a room typically requires adequate fire resistance, proper ventilation, and external access facilities. In the tragedy at Hongfu Yuan, many victims were trapped in environments fully exposed to flames and dense smoke precisely because their homes lacked such a safe space, rendering escape through the entrance impossible. Fire doors serve not only as isolation barriers but also as vital life-saving devices. They effectively block high-temperature flue gases, providing trapped individuals with a survival window ranging from several minutes to several hours.
If each suite includes a room equipped with qualified fire doors and corresponding structural features, forming an effective "fire refuge," it can provide residents with a final safe haven even if the fire spreads to their homes. This design has been mandated in building codes across many countries, particularly for high-rise residential buildings.
The third line of defense: the compromised fire separation in the stairwell
◇ As a vertical evacuation route, the fire resistance of stairwells is paramount. An ideal stairwell should be completely isolated from other floors by fire doors, forming a "safe evacuation pathway." However, during the Hongfuyuan fire, the fire doors in the stairwell failed to function properly, allowing flames and dense smoke to rapidly spread upward through the space, transforming what should have been a lifeline into a deadly hazard.
The failure of fire doors may stem from various causes:
▪ The product itself is non-compliant and fails to meet the specified fire resistance duration;
▪ Improper installation with gaps present;
▪ Inadequate daily maintenance, including damage to the door closer or illegal fixation of the door leaf for opening. Regardless of the cause, the outcome is catastrophic—a complete collapse of the fire separation system.
If the fire doors in stairwells function effectively by interrupting the spread of flames through vertical passages, residents on other floors still have a significant chance of safe evacuation via the stairs even in the event of a fire on a particular floor. This represents one of the most fundamental and critical principles in fire safety design for high-rise buildings.
Comprehensive Reflections and Improvement Suggestions
The tragic lessons from the Hongfuyuan fire demonstrate that building fire safety is a systematic endeavor, where any oversight in any aspect can lead to the collapse of the entire defense system. The three lines of defense—fire protection of the external envelope, provision of indoor refuge spaces, and fire separation of vertical passages—must work in concert to form an effective fire prevention framework. From this tragedy, we can draw the following insights:
▪ Strengthen comprehensive lifecycle supervision of fire protection products
From production and sales to installation and maintenance, a stringent quality control system must be established to ensure that fire protection products function effectively during a fire emergency.
▪ Revise and implement stricter building fire safety regulations
For the renovation of existing buildings and the construction of new buildings, fire safety standards should be elevated, particularly by imposing mandatory requirements for fire-resistant windows, indoor fire doors, and fire compartments in stairwells.
▪ Strengthen public fire safety education and emergency drills
Residents should be aware of the locations and usage methods of fire protection facilities within buildings, master fire escape techniques, and minimize erroneous decisions caused by panic.
▪ Establish a regular inspection system for fire protection facilities
The building management shall regularly inspect and maintain fire safety facilities to ensure they remain operational.
As a high-density city, Hong Kong faces particularly severe challenges in building fire safety. The Hongfu Yuan fire should serve as an opportunity for reflection and action across the entire industry and society. Behind every fire door and fire-resistant window lies a commitment to human life. Only when these commitments are diligently fulfilled can the city truly be considered safe.As a high-density city, Hong Kong faces particularly severe challenges in building fire safety.

While mourning the deceased, we must transform our grief into concrete actions to ensure such tragedies do not recur. Fire safety is no trivial matter; the refinement of every detail may save countless lives in the future.
