Two men have been taken to hospital after four hectares of a corn field in Orpington were on fire.

The large fire broke out in a field on Crockenhill Road yesterday (July 30), causing a major response from the London Fire Brigade.

Six fire engines and about 40 firefighters were called to fight the blaze, which damaged around four hectares of cornfield.

The fire also damaged part of a tractor and two electricity pylons.

One man was treated at the scene, and two others were taken to the hospital by London Ambulance Service.

The fire brigade was called at 4.30pm, and the fire was under control by 6.10pm.

Crews from Orpington, Erith, Sidcup, and nearby fire stations, along with firefighters from Kent Fire and Rescue Service, were at the scene.

The firefighters used a special All-Wheel Drive (AWD) vehicle from Biggin Hill Fire Station, which can carry about 1,000 liters of water and reach difficult areas.

Firefighters were well-trained for grass fires and wildfires, and a Wildfire Support Officer was there to help the Incident Commander.

Firefighters were given extra water, sun cream, and protective hats to keep them safe in the hot weather.

The London Fire Brigade is also trying out new wildfire response vehicles this summer, which can pump water while driving to put out fires faster.

The fire happened during a heatwave, with temperatures over 30 degrees Celsius and a yellow Heat Health alert in place.

The Brigade warned that grass fires are more likely in this weather and asked the public to be careful.

London Fire Brigade Assistant Commissioner for Prevention and Protection, Craig Carter, said: "We know many Londoners will want to enjoy the nice weather by visiting a park or open space.

“However, we’re asking people not to take disposable barbecues with them as they can cause grass fires, especially in hot weather when the ground is dry. These fires are unpredictable and can spread rapidly, causing a significant amount of damage.

"Don’t be tempted to barbecue on your balcony either. Balconies can contain combustible materials which can pose a risk to those barbecuing and others living nearby.

"If you are having a barbecue, never leave it unattended and be careful where it’s positioned. Aim for level ground and keep barbecues well away from anything flammable like sheds, fences, trees or tents."
