16 London firefighters were injured and two were taken to hospital yesterday during the busiest day for the Brigade since WWII.

The London Fire Brigade received 2,670 calls, rather than the 500 they receive on a regular busy day.

The hot weather, which reached 41C in some places, meant firefighters dealt with more than 1,146 incidents across London in one day.

This included a number of fires across south London, including a major warehouse fire in Erith where 28 people had to be rescued.

The London Fire Brigade has revealed that 16 firefighters suffered heat-related injuries and two went to hospital, but have now been released.

They added that, although the major incident is now over, they will be starting investigations into the causes of the fires.

There were no fatalities across any of the incidents, thanks to the “heroic” action by firefighters.

Jonathan Smith, the Assistant Commissioner, said: “I am immensely proud of the firefighters and their dedication in such unprecedented heat.

“Yesterday’s fires are another example of how we are increasingly being challenged by new extremes of weather as our climate changes and we’re developing long-term strategies to deal with more incidents like this in the future.”

A spokesperson for the London Fire Brigade said: “London Fire Brigade had its busiest day since World War II yesterday as record temperatures led to hundreds of fires across the city.

“The scale and frequency of the fires caused the Brigade to declare a major incident yesterday afternoon to allow for resources to be focused.

“There were more than 1,146 incidents throughout London yesterday, and thanks to the heroic work of firefighters, there were no fatalities.

“More than 40 houses and shops were destroyed after a number of significant grass fires spread to nearby buildings, including in Wennington, Dagenham and Kenton.

“Crews worked tirelessly to tackle fires which also engulfed garages, farm buildings, vehicles, outbuildings, a car wash and a church hall.

“A total of 16 firefighters suffered heat-related injuries, and two of them were taken to hospital.

“Control Officers also worked relentlessly throughout the day, taking 2,670 calls between 0800 yesterday and around 0630 this morning.

“The Fire Investigation team was also exceptionally busy, mobilising to fires around London.

“Efforts will continue in the coming days to attend scenes and determine causes where possible.

“In the aftermath of the fires, Borough Commanders and their stations will be engaging with people in communities affected by the fires to offer our ongoing support.

“The Brigade declared the major incident over this morning.

“Firefighters remain ready to respond to incidents throughout today and the Brigade is continuing to monitor the weather conditions and the forecast for the coming days, with additional resource in place today.

“It is likely to be another warm day, with a yellow weather warning in place from the Met Office of storms and thunderstorms for London.

“After a month with little rain, much of the land in the capital is dry which means that heavy rain could lead to surface water flooding.”

The Brigade’s Assistant Commissioner, Jonathan Smith, said: “Firefighters across London worked in very difficult conditions to protect Londoners and their heroic actions mean no lives were lost.

“I am immensely proud of them and their dedication in such unprecedented heat.

“We declared a major incident and worked with emergency service partners who have also been working hard to continue to run services in these difficult and challenging conditions.

“By taking action, we were able to focus and prioritise our resources, recall staff from training, call on support from other local fire and rescue services and attend every incident as needed.

“Yesterday’s fires are another example of how we are increasingly being challenged by new extremes of weather as our climate changes and we’re developing long-term strategies to deal with more incidents like this in the future.

“Despite some rain in parts of London overnight, the ground is still likely to be dry, so as well as fires there is also a risk of surface water flooding.

“If you are at risk of flooding, you can take action now to prepare.

“Please continue to pay attention to weather alerts and prepare a flood kit or grab bag.”
