Six-Day Fire at Heathrow Substation Finally Out
A massive blaze ripped through a high-voltage electrical substation near Heathrow Airport, sparking chaos and sparking a massive emergency response. The fire, which broke out just before midnight on 20 March, was finally extinguished six days later.
Epic Battle with Oil-Fuelled Transformer Blaze
The London Fire Brigade (LFB) confronted a tough firefight. The transformer contained highly flammable insulating oil, making the fire extremely dangerous. Firefighters first subdued the flames by 6.28am on 21 March but had to tackle lingering hotspots for days. They used foam, misting jets, and indirect cooling to safely bring the inferno under control.
At its peak, the emergency operation involved:
- 10 fire engines
- 2 Bulk Foam Units
- 1 High Volume Pump
- About 70 firefighters
The Brigade’s drone unit was also key, using thermal imaging to find hidden flames in hard-to-reach spots.
Safety First: Evacuations and Major Incident Declared
A safety cordon stretching 200 metres forced roughly 150 locals from their homes. Luckily, no injuries were reported despite the tense situation.
Deputy Commissioner Jonathan Smith praised the crews:
“Our firefighters worked tirelessly in challenging and hazardous conditions overnight to bring the fire under control as swiftly as possible. I would like to take this opportunity to thank firefighters, Control officers and staff for their courage and professionalism in bringing this incident under control.”
Investigation Finds Electrical Failure to Blame
The Metropolitan Police declared a major incident just after midnight on the night the fire began, given the risk posed by the flammable materials and critical infrastructure nearby.
Fire crews stuck around, waiting for the oil fire to subside before launching a final offensive with water monitors on 26 March.
A joint probe by LFB and Met Police rules out foul play. Electrical equipment failure is the suspected cause. LFB will continue investigating with Fire Safety Officers under the Regulatory Reform (Fire Safety) Order 2005.
Local residents have now returned home and normality should soon resume once the investigation wraps up.
