Smoke is still emanating from the remains of a warehouse in Newport Pagnell which was almost completely destroyed by fire yesterday.
An investigation into the cause of the fire will begin in this morning.
At its peak, 60 firefighters from as far as Dunstable were needed to tackle the blaze in Renny Park Road, which was first reported at 1.50pm.
A total of 77 calls were made to the emergency services to report the fire.
Two turntable ladders and two water tankers were brought in and the fire was eventually said to be under control at around 5.15pm.
Everyone in the building was able to get out safely when the fire was discovered and there have no reports of injuries to staff, the public or firefighters.
North Crawley Road and Renny Park Road were closed for several hours and relief fire crews were working at the scene overnight.
Bucks Fire & Rescue area manager Mick Osborne said: “Crews worked extremely hard to bring the fire under control while preventing it from spreading to adjacent premises, and protecting the environment.”
Group manager Steve Wells, the incident commander, added: “Firefighters worked extremely hard, in very difficult conditions, to bring a rapidly-developing fire under control in a little under four hours, while also preventing it from spreading to adjacent premises, and protecting the environment.
“I would also like to thank all the other agencies who worked with us to bring this incident to a safe conclusion, including Thames Valley Police, Milton Keynes Council, the Environment Agency, Public Health England, the British Red Cross and the gas, water and electricity companies, as well as the media for their prompt help in spreading important safety messages while the incident was ongoing.
“Thanks, too, to adjacent businesses who made their facilities available to us.”
