SCDF Utilised Thermal Imaging Cameras to Detect Heat Spots

The Singapore Civil Defence Force (SCDF) employed thermal imaging cameras as a key technology to identify and pinpoint areas of residual heat during firefighting operations. These cameras were instrumental in guiding firefighters to direct their water jets precisely at affected zones, ensuring a targeted and effective approach to extinguishing fires.
Guiding Firefighting Efforts with Thermal Imaging

During the firefighting and "damping down" operation at the Jurong East flat on August 17, SCDF firefighters deployed thermal imaging cameras. This technology allowed them to visually identify "heat spots" within the affected unit. The data provided by these cameras enabled the crew to accurately target their water streams at the specific locations where heat was concentrated, thereby maximising the efficiency of their efforts.
Assessing Debris and Temperature Levels

The use of thermal imaging cameras was part of an extensive eight-hour "damping down" operation. This process was deemed necessary to manage the challenging conditions within the unit, which contained a large volume of closely packed debris. Firefighters used the cameras to monitor the temperature of the debris. Operations concluded when the thermal imaging cameras indicated that the debris had returned to normal ambient temperature levels and no further heat spots were detected.
Investigating Potential Causes of Re-ignition

Despite the measures taken, including the use of thermal imaging cameras, a fire re-ignited in the master bedroom the following day. The SCDF spokesperson indicated that the cause was likely due to deep-seated embers that were not detected by the thermal imaging cameras. This incident prompted an internal review by the SCDF to assess if additional measures are required for similar future incidents, while ensuring the fire scene was preserved as intact as possible for investigation.
