Core Points - The fire at Hong Kong's Hongfu Garden resulted in significant casualties, with 75 confirmed dead and 76 injured, including firefighters [2][4] - The existing firefighting equipment in Hong Kong, particularly the main "turntable ladder" with a maximum operational height of 56 meters, is inadequate for high-rise buildings like the 32-story Hongfu Garden [6][8] - The physical limitations of the firefighting equipment and the building's design hindered effective rescue operations, leading to a reliance on ground personnel for firefighting efforts [5][10] Group 1: Fire Incident Overview - The fire at Hongfu Garden, which has a height exceeding 90 meters, posed challenges for firefighting due to the limitations of existing equipment [6][8] - The rescue operation involved over 1,200 firefighters and paramedics, with more than 200 fire trucks and 100 ambulances deployed [4][5] - The fire's intensity and the building's height created a "vacuum zone" where traditional firefighting equipment could not reach [8][9] Group 2: Equipment Limitations - The main firefighting equipment, the "turntable ladder," can only reach up to 56 meters, which is insufficient for the 32-story building [6][8] - The narrow internal roads of the building complex restricted the deployment of heavy firefighting vehicles, preventing them from fully extending their support legs [9] - Water pressure loss over long distances further complicated firefighting efforts, limiting the effectiveness of water streams on high floors [10] Group 3: Emerging Solutions - New emergency rescue vehicles utilizing high-pressure jet technology are being developed to address the limitations of traditional firefighting equipment [11][12] - These new vehicles can reach heights of up to 160 meters, theoretically covering most residential buildings [12] - The introduction of such technology is still in its early stages, with limited deployment in existing firefighting systems [12] Group 4: Drone Utilization Challenges - The use of drones for firefighting has been questioned, with current models unable to effectively combat high-rise fires due to environmental conditions and payload limitations [14][16] - Existing drones are primarily used for reconnaissance rather than direct firefighting, highlighting a gap in technology for high-rise fire scenarios [15][19] - The need for a coordinated drone operation involving multiple units is emphasized, but such systems are not yet established in the industry [19][20]
