A man had to run through the flames to escape a fire which broke out at an industrial unit in Setchey earlier today..
At its height, more than 50 firefighters from across Norfolk were called to tackle the blaze at the WN Surfacing site on Garage Lane this lunchtime.
The fire is thought to have started in a shipping container before spreading to a workshop rented by Pocknell Engineering.
The injured man is believed to have been cleaning tools in the unit at the time.
Director Lucy Pocknell, who was on site at the time, said: “I heard him shout for help and we came running round as he came out.
“He had to run through the flames to get out.”
The man was treated for burns at the scene by paramedics before being taken to the Queen Elizabeth Hospital. His injuries are not believed to be life-threatening.
Miss Pocknell said the fire had spread to the wall of her firm’s workshop and destroyed three containers of equipment.
But she said the damage to the workshop would have been worse without the asbestos in its wall, which reflected the heat of the fire for some time.
At the height of the blaze, crews from as far afield as Wymondham and Thetford were called in to work alongside colleagues from Lynn, Downham, Hunstanton, Terrington, Sandringham and Fakenham.
The area was also evacuated because of safety concerns about a number of gas canisters and a quantity of fuel on the site.
The Norfolk Fire and Rescue Service said the incident was not believed to be suspicious.
