More than 50 firefighters have been tackling a large blaze at a car repair and furniture workshop in Hampshire.
One eyewitness described seeing "a huge explosion" and a "fire ball at least 50 to 60ft high" coming from the building in Denmead, near Waterlooville.
Emergency services were called to Sheepwash Lane shortly after 16:00 GMT.
Hampshire Fire and Rescue said everyone had been accounted for. Two men were treated for minor burns and left in the care of the ambulance service.
The blaze, which involved gas cylinders, was brought under control by 18:00. A cylinder valve was later found in a nearby field.
A spokesman said the service received lots of calls and large plumes of black smoke were visible from surrounding areas. Yup - we could see a huge plume of black smoke from our house. Thank God that no-one was hurt.
