More than 100 firefighters have been deployed to field fires across Orpington over the last two days.

London Fire Brigade is urging the public to follow “crucial safety advice” that will help protect themselves, others, the environment and their property.

Below are the four fires which have occurred in Orpington since Monday:

Charmwood Lane field fire

At 12.23pm on Monday (July 30), four fire engines and 25 firefighters were called to a fire in a field on Charmwood Lane in Orpington.

Around four hectares of straw was damaged by fire.

Crockenhill Road cornfield fire

At 4.30pm on the same day, six fire engines and around 40 firefighters were called to a fire in a field on Crockenhill Road in Orpington.

Around four hectares of cornfield were damaged by fire.

Part of a tractor and a small part of two electricity pylons were also damaged by fire.

Hawstead Lane waste material fire

On Tuesday (July 31), five fire engines and around 30 firefighters were called to a fire in a field on Hawstead Lane in Orpington at 4.36pm.

A range of non-hazardous waste material was damaged by fire.

Charmwood Lane hay and stubble field fire

At 12.52pm today (August 1) 30 firefighters were called to another fire in a field on Charmwood Lane in Orpington.

The fire has partially damaged an area of hay and stubble field with the cause of fire yet to be confirmed.

Firefighters have been supported at these incidents by the Brigade's All-Wheel Drive (AWD) vehicle.

Permanently introduced earlier this year, the AWD vehicle, which is based at Biggin Hill Fire Station, can do many of the same tasks as a standard appliance, such as pump water with a capacity of around 1,000 litres.

The vehicle's four-wheel drive capability also means it is easier to reach incidents in more remote locations than standard fire appliances, helping to support the Brigade all-year round, including at grass fires.

Station Commander for Orpington Mark Niblett said: "These fires have come as London experiences high temperatures with a yellow Heat Health alert issued by the UK Health Security Agency.

"During this type of weather, the risk of grass fires increases and we’re asking those in the local areas to help the Brigade prevent further fires.

“Only this week we’ve been called to several fires in fields in the Orpington area."

Borough Commander for Hillingdon Paul Eastland said: "All firefighters have received enhanced training for grass fires.

"The welfare of operational crews working in hot weather conditions is a key priority and firefighters are provided with additional hydration packs, sun cream and protective headwear for personal protection on the incident ground."

London Fire Brigade is also trialling new wildfire response vehicles this summer, which have off-road capabilities and technology that allows firefighters to pump water while driving, enabling them to tackle an outdoor fire more quickly and safely.

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."
